Multiwave PRO
Master of Sample Preparation Methods
HPA–S
Unrivaled Performance
4The Multiwave PRO microwave reaction system delivers the sample
preparation solutions you need to obtain excellent trace analysis
results, even with complicated, demanding samples.
The High Pressure Asher HPA–S is the reference instrument for wet
chemical pressure decomposition. The instrument is TÜV certified
and can prepare even the most difficult samples for reliable AAS,
ICP-AES, ICP-MS and voltammetric analysis.
4Multiwave PRO masters high temperatures and provides
comprehensive reaction control features.
4Its wide range of accessories allows digestion, leaching, oxygen
combustion, solvent extraction, drying, evaporation, and UV
digestion with one single system.
The HPA-S enables the maximum decomposition parameters and
the largest sample weight in hermetically sealed reaction vessels
made of quartz glass or glassy carbon. Uniform heating and exact
temperature control guarantee the highest level of reproducibility.

Highest
decomposition quality
Digestion rotors with up
to 64 vessels eliminate
the bottleneck in sample
preparation while being fast
and easy to operate without
compromising safety.
Operating pressures and
temperatures up to
80 bar and 300 °C result
in matrix-free solutions
without contamination or
loss of analytes, even for
samples which are difficult to
decompose or react violently.
Simple operation and a comprehensive library of
applications make the Multiwave PRO a powerful tool for
sample preparation.
Everything under control
Integrated cooling
Continuous pressure monitoring of all eight sample vessels allows
for safe and precise reaction control, even with critical samples.
Information about reaction parameters is delivered by installationfree pressure and temperature sensors from a reference vessel.
The reaction vessels can be operated at maximum operating
pressure and maximum temperature simultaneously. The
integrated vessel cooling prevents overheating and ensures a
higher sample throughput due to short cooling times.
An external IR sensor monitors the temperature of all reaction
vessels at the base of each vessel.

Multiwave PRO
Special Applications
Multiwave ECO
Routine Digestions - Simple and Quick
Microwave-assisted extraction
Multiwave ECO is a quick and convenient microwave digestion
system equipped with the lightweight Rotor 16HVT50. This rotor
has a superior design for controlled release of overpressure.
Multiwave ECO simplifies your routine handling of environmental,
food and many other samples. The low investment and operating
costs of Multiwave ECO and low costs for consumables make it a
good investment.
Extraction above the solvent's boiling point for unmatched
speed and safety.
Oxygen combustion
Microwave-induced combustion is a unique option for analysis of
halogenes or metals in combustible samples.
UV digestion
Microwave-powered UV lamps completely destroy organic matter in
liquid samples with little reagent and low analytical blanks.
Hydrolysis
Protein hydrolysis can be performed from milligram to gram scale in
less than one hour, even under inert gas atmosphere.
Evaporation
Acids or silicates are removed under clean room conditions without
changing the reaction vessel.
Drying
Samples are dried prior to digestion quickly and without bad smells.
