Differences between the cartridge holders
Compared to the standard FlexStand cartridge holder (FS-01S) the low-void-volume
FlexStand (FS-03LVS) cartridge holder has smaller inside diameter manifold ports and
tubing. The standard system uses 1.5-inch sanitary connectors and the low-void-volume
system uses fractional sanitary connectors.
The main components of a FlexStand cartridge holder are:
• Supporting rods, base, and manifolds
• Pressure gauge
• Backpressure control valve
• Tubing connector kit
The following sections describe these and other key components.
Instructions 18-1174-61 AC
7
Supporting rods, base, and manifolds
The stand consists of a base plate, supporting rods, and two adjustable slider assemblies
with manifolds. The base plate holds the supporting rods which in turn support the slider
assemblies and manifolds.
The slider assemblies move up and down along the support rods and lock into positions
that enable you to mount various length cartridges between the manifolds.
The manifolds serves several functions: they direct the flow of process solution into and out
of the cartridge and they enable the attachment of the pressure gauges and process
tubing.
Pressure gauge
The FlexStand cartridge holders includes one, 0 to 4 barg (0 to 60 psig) pressure gauge to
monitor feed pressure. The mechanically dampened pressure gauge connects to the feed
and retentate ports using sanitary connectors.
You can order and mount optional pressure gauges to monitor retentate and permeate
pressure.
Backpressure control valve
The FlexStand cartridge holders include a heavy duty pinch valve that enables operators
to control the backpressure in the filtration system. The retentate tubing is placed in the
clamp and a hand knob enables operators to tighten or loosen the clamp, affecting the
backpressure on the system.

hollow fiber cartridge after use, you simultaneously flush and clean the FlexStand cartridge
holder, thus no further flushing is needed.
If the last operation you perform with the cartridge holder is to flush the cartridge with a
storage solution, you must then flush the holder with DI water or WFI to remove the storage
solution. Position an old cartridge or a short piece of flexible tubing with sanitary adaptors
in the cartridge position to flush the system with water.
After use, you should wipe down the exterior components of the FlexStand cartridge holder
with water to remove dirt and residual process/cleaning solutions. Wipe the system dry
with a clean, lint-free cloth.
Storing the holder
To store the holder for more than a few days, clean it as described in the maintenance
section. Drain all rinse water from the system. Remove the cartridge from the FlexStand.
Blank off open lines or ports in the system and reservoir. Store the cartridge in accordance
with the instructions in the cartridge user guide (in general, well-sealed with ultrafiltration
membranes kept wet in storage solution) and stored at cool or ambient temperature.
System disposal
When the service life of the system is reached, flush the system to remove hazardous
