2. Introduction
The Vision Microette is a programmable precision syringe-pump sampling instrument that handles a
wide variety of diffusion applications and requirements. The basic instrument consists of 6 sampling
syringes driven by a stepper motor, with internal valve interfacing, in one compact ergonomic
instrument package. Teflon tubing harnesses connect diffusion cell groups to AutoFill™ collectors
for completely automated diffusion sampling.
The Vision Microette can be directed to withdraw an aliquot from a diffusion cell group at a preprogrammed time. The sample is dispensed into a collection rack that contains vials or test tubes.
The Vision Microette can be programmed to repeat this process multiple times.
The AutoFill is an automated fraction collector designed for seamless integration with the Vision
Microette. The AutoFill includes sample collection capability from six sources, home port array for
waste, all-inert tubing and dispense probes, and reduced tubing lengths to minimize rinse volume
and save time. Collection racks include 16 x 100 mm test tubes for UV, 13 x 100 test tubes for UV,
12 x 32 vials for HPLC, and 12 x 32 vials for UPLC (the UPLC rack holds three trays for Waters
Acquity UPLC).

5.1 How the Vision Microette Works
Before beginning operation of the Vision Microette, the operator should have a thorough
understanding of how sampling is performed and how this may affect method development.
While dissolution sampling involves withdrawing a sample and then possibly adding
replacement media, the Hanson vertical diffusion cell is sampled by pushing the sample out
with new media. This is done under specific conditions in order to avoid diluting the sample.
1.
The stirrer is stopped 30 seconds prior to the sample point. The syringes also load fresh
receptor media from port D.
2.
New media is slowly pumped into the cell through the replace port at a rate of 1.2
mL/min.
Page 39 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
3.
This results in the diffusion cell becoming pressurized.
4.
The sample is pushed out the sampling port to the AutoFill.
Because the fresh receptor media is pumped in slowly, it does not mix with the existing media.
In order to ensure sample volumes are accurate, Rinse and Collect delays are used, which
keep the needles in place to allow time for the pressure within the cell to equilibrate. The
sample will always follow the path of least resistance. In a properly working system with
sealed diffusion cells, this will be the sample port out to the AutoFill. If the diffusion cell is
leaking, the sample will find another way out.
Page 40 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
In some cases, it will be obvious that diffusion cells are leaking. In other cases, the leak may
be harder to find. The typical symptoms of a leak are:



Fresh media appearing around the diffusion cell during a test
Sample vials are empty or not filled to the correct volume
AutoFill needles drip between sample points
Typical causes of diffusion cell leaks are:




Irregular or rough membranes, which prevent the cell from sealing
Membranes that flex during sample points, resulting in leaking
Insufficient amount of material on top of membrane, which causes the receptor media
to be pushed into the donor chamber
Clogs in the tubing between the sample port and AutoFill needles
NOTE: Anything that increases the pressure inside the diffusion cell can potentially
cause a leak. This includes increasing the delivery speed of the Vision Microette.
With this style of sampling, it is also important to maintain control of the volume entering the
diffusion cell. If the cell is overfilled during a test, fresh media may be pushed into the AutoFill
lines, which will dilute the sample. The following table lists the volumes of media which can
be pumped into the diffusion cell without unintended dilution of the sample.
Cell Volume
4 mL
7 mL
12 mL
Maximum Amount Pumped
Without Dilution
2.0 mL
2.5 mL
5.0 mL
Figure 5.1 Maximum Amount of Volume Without Dilution Table
NOTE: A 2 ft tubing harness is included to reduce the rinse volume requirements. It is
strongly recommended to use this between the diffusion cells and the AutoFill.

If a diffusion cell group or media is not configured to a particular port, then it will not be
possible to utilize it using the Automatic Syringe Controls. If material must be transferred
to an unconfigured port, refer to the Transfer command under Manual controls. The
following tabs are available for Automatic Syringe Control.
Sample: This allows the user to sample the specified volume from the specified cell
group. The source for this function is always port D.
Collect Volume: The sample volume to transfer (0.0- 99.9 mL). The recommended
maximum capacity of 16 x 100 test tubes is 15 mL and 12 x 32 HPLC vials is 1.5 mL.
Target: The diffusion cell group from which the sample is collected. This can be set to
A, B, or C.
Target Row: The collector row to which the sample is delivered. This is a numeric
value that depends on the type of collector rack used.
Dispense Speed: The speed at which the syringes dispense the media. Slow
(default) dispenses the syringes at 1.2 mL/min and is appropriate when working with
assembled diffusion cells. Fast will dispense the syringes at 9.9 mL/min and is
appropriate when working with diffusion cells when the cell tops are removed.
Prime: Allows the user to prime the lines and fill the diffusion cells before starting a test.
This function should only be used when the cell tops are removed. The system will pump
at the fast speed (9.9 mL/min) and is likely to cause leaks in an assembled diffusion cell.
Page 57 of 101
59-108-001 Rev. B

Prime Volume: The amount of volume to be transferred. This can be set from 0 mL to
99.9 mL using the numeric keypad.
Source: Toggles the port from which the material is pulled. This will typically be set to
D for clean media.
Target: Toggles the port to which the media is delivered. This can be set to A, B, C or
ALL diffusion cell groups.
Repeat: Allows the user to enter the number of additional times to implement the
transfer. This can be set from 1 to 9999. For example, if a volume of 10 mL from
Source D to Target A with a Repeat of 2 was selected, the Vision Microette will
transfer 10 mL from D to A twice, for a total of 20 mL.
Rinse: Allows the user to rinse the sample lines in preparation for collection of a sample.
The system will pump at the slow speed (1.2 mL/min) and is safe to use on sealed
diffusion cells.
Rinse Volume: The amount of volume to be transferred. This can be set from 0 mL to
99.9 mL using the numeric keypad.
Target: Toggles the port to which the media is delivered. This is typically set to A, B
or C for diffusion cell groups.
NOTE: The source for the Rinse function is always D for fresh receptor media.
The Manual Syringe Control screen is accessed by touching the Manual button at the
bottom of the screen. The Manual Syringe Control screen allows the user to execute
basic controls over the Vision Microette syringes. These functions are primarily used for
maintenance and troubleshooting of the system.
Transfer: Allows the user to transfer a programmed volume of media from a source port
to a destination port regardless of whether the port has been configured. The transfers
are executed at the full pumping speed of 9.9 mL/min. It is recommended to only use this
Page 58 of 101

with open diffusion cells, as sealed diffusion cells may leak due to the sudden increase in
pressure.
Volume: The amount of volume to be transferred. This can be set from 0 mL to 99.9
mL using the numeric keypad.
Source: Toggles the port from which the material is pulled. This will typically be set to
D for clean media.
Target: Toggles the port to which the media is delivered. This is typically set to A, B
or C for diffusion cell groups.
Repeat: Allows the user to enter the number of additional times to implement the
transfer. This can be set from 1 to 9999. For example, if a volume of 10 mL from
Source D to Target A with a Repeat of 2 was selected, the Vision Microette will
transfer 10 mL from D to A twice, for a total of 20 mL.
Load: Allows the user to load the specified volume from the specified source. After this is
executed, the Vision Microette will stop and await the next command. Volume for the load
command is restricted to the maximum amount the syringe can hold, 2.5 mL.
Dispense: Allows the user to dispense the material in the syringe to the selected target.
If dispensing to Target A, B or C, the needles of the AutoFill are automatically lowered, but
the user must ensure that the needles are located over the proper row in order to avoid
spillage. Dispense is executed at the full pumping speed of 9.9 mL/min. It is
recommended to only use this with open diffusion cells, as sealed diffusion cells may leak
due to the sudden increase in pressure.
Valves: Allows the user to open and close the valves located within the unit. Touching
the red button located next to each port letter will open the valve for that port.

It can also be accessed from the home screen by touching [Select Protocol] (or protocol
name) displayed in the upper left corner of the screen.
Protocols are a list of parameters and events that are required to perform a diffusion test.
These parameters can be modified to accommodate user needs. Up to 100 different
protocols can be stored.
The Recent tab displays the protocols which were used most recently.
The Page # tabs display the protocols in alphabetical order based on protocol name.
The protocols are listed alphanumerically by protocol name in groups of 5 (4 groups per page)
over 5 pages within the interface.
Buttons on the right of the Protocol screen are:
Checksum: This button generates a unique checksum for the protocols. This can be
used to ensure a restored set of protocols is identical to the original set. When touched,
the Protocols check pop-up is displayed, which first informs the user the value is being
calculated, then displays the calculated value.
Page 62 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
For example, an operator touches the Checksum button and obtains a value of 0EA4.
The operator then changes a protocol label by 1 character. When the operator
touches the Checksum button again, it will generate a different value.
This feature can be used to ensure that backups and restorations of protocols are
identical to the originals. The feature can also be used by managers to ensure that
protocols have not been changed without authorization.
Archive: Allows Backup and Restore functions.
Backup: This button allows all existing protocols to be saved on the flash drive,
which must be inserted into the USB port to the left of the touchscreen. When this
button is touched, the Protocol Backup pop-up is displayed, which prompts the
user to insert a flash drive into the USB slot if it is not inserted. If the flash drive is
already inserted, it writes the protocols to the drive and the pop-up disappears. All
protocols will be saved to a file named mproto.bak.
Restore: This button allows protocols to be restored from the flash drive inserted
into the USB port. All protocols will be restored from the mproto.bak file.
NOTE: The restore function will produce an exact copy of the protocols on
the flash drive. All existing protocols will be overwritten.
If the mproto.bak file does not exist, then a pop-up error message is
displayed and the message is also written to the error log. The message
asks the user to confirm protocol restoration. If the user touches No, then
the protocols will not be restored. If the user touches Yes, all the protocols
will be overwritten.
Import: This button allows the user to import all previously exported protocols from a flash
drive inserted into the USB port. Protocols must have been previously exported to the
flash drive in order to import them. Only protocols with differing protocol names will be
added. Existing protocols may be overwritten if the user confirms an overwrite; otherwise,
the existing protocols will remain.

Protocol Name: This is the name of the protocol and must be unique. The
Protocol Name is how the protocols are organized on the protocol selection
screens.
Comments: Allows the user to add any notes specific to the protocol.
The following field names can also be edited by the user though the Configuration
settings, in the Edit Titles screen.
Drug Name: The name of the drug the protocol is designated to test (e.g.,
hydrocortisone).
Dosage: The dosage size of the drug to be tested (e.g., 300 mg).
Protocol ID: A secondary ID for the protocol; this does not need to be unique.
Membrane: Lists the type of membrane used for the diffusion protocol (e.g.,
polysulfone, mouse skin).
Media Type: Lists the type of receptor media used for the diffusion test (e.g., water,
30% ethanol).
Media Volume: Lists the approximate volume of the diffusion cells used for the test
(e.g., 4 mL, 7 mL, 12 mL).

Stirring Speed: The target drive speed for the diffusion test. The parameter is
rpm, and the range is 0, 100-2000 rpm. The stirring control only recognizes
increments of 10.
NOTE: Only set points in increments of 10 will be recognized by the stirring
control. If a speed is entered that is not in an increment of 10, it will be
rounded lower. For example, if a user entered 326, the stirrer would run at
320 rpm.
Temperature: The target temperature of the diffusion cells. Range is 0, 25.00 55.00 °C.
Test Length: The total time of the diffusion test. Range is 0-999:00 (hh:mm).
Print Interval: The interval at which the diffusion test system status (speed,
temperature, etc.) will be printed. The range is 0 to 999:00 (hh:mm). If the user
does not wish the status to print the Print Interval should be set to 00:00.
Temperature Tolerance: The tolerance for the temperature in the waterbath. The
recommended value is ± 0.5 °C. Range is 0 (off), 0.10 to 5.00 °C.
The Sampling tab allows the user to select the sampling mode and specify all the parameters
related to sampling.
Rack Type: The type of rack used for sample collection during the test. 16 x 100, 13 x
100, 12 x 32 (default), and 12 x 32 UPLC.
Rinse Volume: The amount of volume pumped before collection occurs. This value
should be large enough to remove old sample from the sample lines, but not so large as to
dilute the new sample within the diffusion cell. The range is 0-99.9 mL.
NOTE: Refer to section 5.1 on the amount of media volume that can be removed
from a diffusion cell without diluting the sample.
Page 67 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
Collect Volume: The volume collected into test tubes or vials during a sampling cycle.
The range is 0-99.9 mL. The maximum for 16 x 100 test tubes is recommended to be no
more than 15 mL; for 12 x 32 vials, no more than 1.5 mL.
Cell Group Offset Time: This determines the offset between the diffusion cell groups
when running multiple diffusion test systems. The minimum recommended value is 0:05
minutes. The range is 0:00 to 1:40 (H:MM).
Pre-Start Rinse Time: Allows the user to set the Vision Microette to start the pumping
ahead of the scheduled sampling time to allow for fine-tuning sample points. The range is
1 to 3600 seconds (1 second to 1 hour).
The Events tab allows the user to add events or modify the Event Table.
The Event Table is a sequence of up to 50 events that will take place at user-programmed
times. There are two types of events: sampling and remote commands. Sampling events
must have a time assigned. Remote command events may occur during the test, pre-run
(before the test), or post-run (after the test).
NOTE: Pre-run and post-run events cannot be sampling events.
Pre-Run: Events programmed as a pre-run event will occur before the test begins. For
example, an operator programs a pre-run event of Stirrer Speed for 200 rpm. Prior to the
test starting, the stirrers will spin at 200 rpm. When the test begins, the motor will go to
the speed programmed on the Diffusion tab.
Post-Run: Events programmed as post-run will occur after the test has completed. For
example, an operator programs a post-run event of Bath Temp for 40 °C. Once the test
completes, the circulating waterbath temperature will be set to 40 °C.
To edit or delete an event, touch the field in which it appears; this will open the Edit Event
screen.
To add a new event, touch the Add Event button; the following screen is displayed:
Page 68 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
The Add Event screen allows the user to add an event or events to the event table.
Start Time: This defines the start of the first event. The range is 0:00 to 999:00
(hh:mm). Preset buttons are Pre-Run and Post-Run.
Event Type: This defines the type of event that is to occur. By default, all events
are sampling events. Many of these options require the entry of an Event Time.
Here are the event types:
Sample: Collects a sample.
Bath Temp: The parameter is a temperature value. It allows the user to set a new
circulating waterbath temperature.
Collect Volume: This allows the user to set a new collection volume for the test.
Delay: This allows the user to set a delay of specified amount of time. Range 1 to
12,000 sec. Valid for Pre-Run only.
Dispense Flow Rate: This allows the user to speed up, or slow down the dispense
rate of the syringes during a rinse or sample collection. The range is 0.6 to 23.8
mL/min. The default speed when dispensing during a test is 1.2 mL/min.
NOTE: Increasing the dispense rate beyond the default speed will increase the
chance of a diffusion cell leaking during sampling. 9.9 mL/min. should not be
exceeded, or the Vision Microette could be damaged.
Load Flow Rate: The parameter is speed of the syringes while loading. This changes
the speed at which the Vision Microette syringes load material. The range is 0.6 to
23.8 mL/min. The default setting is 9.9 mL/min.
NOTE: 9.9 mL/min. should not be exceeded, or the Vision Microette could be
damaged.
Post Collect Delay: This allows the user to adjust the delay between when the Vision
Microette stops pumping, and the needles of the AutoFill move up out of the vials.
Page 69 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
This delay is intended to allow excess pressure in the diffusion cell to bleed off for an
accurate sample volume. The default value is 10 seconds. The range is 0.01 to 30.00
seconds.
NOTE: Decreasing the Post Collect Delay from the default value may result in the
needles dripping, and/or an inaccurate sample volume.
Post Rinse Delay: This allows the user to adjust the delay between when the Vision
Microette stops pumping, and the needles of the AutoFill move up out of the waste
lines. This delay is intended to allow excess pressure in the diffusion cell to bleed off
for an accurate rinse volume. The default value is 10 seconds. The range is 0.01 to
30.00 seconds.
NOTE: Decreasing the Post Rinse Delay from the default value may result in the
needles dripping, and/or an inaccurate sample volume.
Print Interval: The parameter is the interval between printing. This changes the print
interval for printing the status of the diffusion test systems.
Print Statistics: This prints the current statistics for the test. There are no
parameters for this command.
Prompt: The message that will pop up at the event time. Up to 11 characters.
Rinse Volume: This allows the user to set a new sample rinse volume (0 to 99.9 mL)
during the test.
Status: This allows the user to get an automatic status at the specified time.
Stirrer Speed: This allows the user to change the stirring speed in the middle of a
test. The parameter is rpm, and the range is 0, 100-2000 rpm. The stirring control
only recognizes increments of 10. If a speed is entered that is not in an increment of
10, it will be rounded lower. For example, if a user entered 326, the stirrer would run
at 320 rpm.
Temperature Tolerance: This changes the diffusion test system temperature
tolerance for the protocol. The options are 0 (disabled), or 0.1 to 5.00 °C.
Transfer: The parameters are Volume, Source, Target, Position. It allows the user
to transfer a specified volume of solution from a specified source to a specified target.
The following sources/targets are available when using a Transfer command in the
event table of a protocol.
U: This source/target keeps the needles of the AutoFill up. It is useful as a
source to pull air into the syringes to dry out the lines.
W: This source/target lowers the needles into the Wash port of the AutoFill. This
can be used if an operator wants to run a protocol for a custom wash configuration.
H: This lowers the needles into the Home/Waste port of the AutoFill.
Page 70 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
1-25: This can be used as a target only. This target will lower the needles into the
corresponding row of the rack. For example, if “10” was entered, the needles
would lower in the 10th row of the installed rack.
A, B, or C: Will keep the collector in the current position when the transfer will
occur. To control which position is used on the collector, add a W, H, or row
number after the target.
NOTE: Using A, B, or C will not lower the needles of the collector when
performing transfers!
Example 1: To perform a 1 mL transfer from source D to group A, row 5 of the
collector – 1.0,D,A,5
Example 2: To perform a 5 mL transfer from source D to group B with the needles
in the Home port – 5.0,D,B,H
Number of Events: This allows the user to set the number of times this event will
occur. By default, only one occurrence of the event is created. For multiple
occurrences, the first event begins at the start time.
Interval Between Events: This allows the user to set the interval between the
events occurring when multiple events are being added to the event table, in the
format hh:mm, where hh is hours and mm is minutes. The range varies depending
on the number of events and the sampling times.

©2014 Hanson Research Corp.
6.
Install the new syringe by screwing it in counterclockwise.
NOTE: When the syringe contacts the manifold, turn no more than 45 degrees in
order to ensure a good seal and not damage the valve.
7.
Using the autosampler controls, open the valves for any lines.
8.
Gently pull the syringe plunger down and align it with the drive bar.
9.
Reinstall the shoulder screw.
NOTE: The shoulder screw should be able to be installed finger tight until it is
flush with the syringe plunger. If the screw cannot be turned with only your
fingers, adjust the plunger and try again. Once the screw is flush with the syringe
plunger, it may be tightened with a screwdriver.
8.4 Sample Volume Calibration
Use DI-grade or better quality water at room temperature.
1.
Weigh empty sample collection vials or test tubes and record (tare weight). Caps are
required in order to ensure accuracy.
2.
Program the autosampler to collect the required the sample volume.
3.
Weigh the filled sample collection vials and subtract the empty (tare) weight from the fill
weight. Make any necessary calculations to account for water density.
Volume (mL) 
Fill Weight (g)  Tare Weight (g)
Density (g/mL)
If the volume does not fall within the specifications in section 3.5, contact Hanson Research
Technical Support.
8.5 Needle Replacement
It is recommended to replace the PEEK needles of the AutoFill annually or as needed.
1.
Remove the AutoFill rack.
2.
Using collector controls, move the AutoFill to the service position.
3.
Gently pull forward and down on the top of the dispense head cover to remove it.
4.
Disconnect each of the PEEK needles from the needle block.
5.
Secure the dispense head cover.
6.
Using the Vision Microette controls, return the AutoFill dispense head to the home
position.
8.6 Cell Volume Calibration
Proper determination of diffusion cell volume is critical for ensuring accurate results. It is
recommended to determine the diffusion cell volume to 3 decimal places.
Page 90 of 101
59-108-001 Rev. B
©2014 Hanson Research Corp.
1.
Obtain a sufficient quantity of room temperature water to perform the cell evaluation on all
of the diffusion cells. Measure and record the temperature of the water with an NIST
traceable thermometer. Determine the density of the water.
2.
Wrap the circulator tubing around the individual cells and connect the ends together as
shown in figure 8.1.
3.
Figure 8.1 Diffusion Cell with Volume Determination Kit Plug Installed
Cut pieces of Parafilm to form small squares that are just large enough to cover the open
orifice in the top of the diffusion cell. If the Parafilm square is too large, or too small,
leaking may occur.
4.
If necessary, dry the inside of each diffusion cell, the helix, and the stir bar using lab
wipes, air, heat, or any other appropriate means to dry the surfaces completely.
5.
Insert the plug from the cell volume kit into the replace port of the first diffusion cell as in
Figure 8.1.
6.
Obtain and record the tare weight of the first diffusion cell.
7.
Fill the syringe from the cell volume kit with room temperature water. The syringe should
be filled with at least 1 mL more water than the theoretical volume of the diffusion cell. For
example, when testing a 7 mL diffusion cell, use a syringe that holds at least 8 mL.
8.
Remove the plug and attach the syringe to the sampling port for the cell. While holding
the cell upside-down, begin to fill the cell with water. If necessary, rotate the cell during
the filling process so that the air is expelled from the replace port. Fill the entire cell but do
NOT fill the bubble trap.

9. Moving and Storage
If the Vision Microette will not be used for a short period of time (3 days or more), the instrument
should be cleaned and the power should be turned off. If the Vision Microette will not be used for
an extended period of time (30 days or more), the instrument should be cleaned, covered, the
circulating waterbath drained, and all instruments unplugged from the power source.
The instrument is heavy and great care should be taken when moving it. If the instrument is moved
to a new location, revalidation should be considered.
Two people are required to lift the Vision Microette and/or AutoFill. Lifting should be done with one
person situated on each side of the instrument. Remove the collection rack before moving the
instrument. Lift the equipment by the base (applies to both Vision Microette and AutoFill).
NOTE: Lifting without assistance may cause injury.

Remove all liquid sources and program the Vision Microette to pump 20 mL of air to
each target to clear as much liquid from the system as possible.
2.
Turn the power off. Disconnect all tubing, communication, and electrical connections
from the unit.
9.2 AutoFill
1.
Turn the power off and remove the rack.
2.
