Microwave Digestion System:
Multiwave

One microwave digestion system for all samples

With Multiwave 7101/7301/7501, digest all kinds of samples – such as food, environmental, polymer, cosmetic, pharmaceutical, geological, chemical, and petrochemical ones – in the same run with the same method. Low blank values and low residual carbon content facilitate elemental analysis. With high temperature and pressure specifications (300 °C and 199 bar), there’s unlimited digestion performance while the magnetron output is automatically adjusted for reactive samples. Powerful stirring aids the digestion of floating samples (optional).

Demanding samples, easy digestion

The PDC (Pressurized Digestion Cavity) revolutionizes your sample preparation workflow:

• Place the vials on the balance 
• Transfer sample weights directly to the instrument
• Add digestion reagents and cover the vials with plug-on caps
• Safely transfer the filled PTFE-TFM rack in a closed PTFE liner (<1 kg)
• Use software-guided, mainly automated opening and closing procedures 
• Rely on automated pressurization, pressure release, and acid fume removal
• Pressure sealing of the vessels avoids cross-contamination

The microwave digestion systems come with ready-to-use methods and customized application support, so method development has never been easier. 

A microwave digestion system fit for any analytical task

Multiwave 7101/7301/7501 microwave digestion systems can accommodate different PTFE-TFM racks so you can perform microwave digestion of up to 28 samples in one run. Up to 4g of sample can be digested in one position. A wide selection of vials is available: Use thin-walled quartz vials that have low blank values or disposable borosilicate vials for routine tasks. PTFE-TFM vials are available for special applications. Use sealed quartz vessels, when working with volatile analytes.

Space-saving and safe

With their compact footprint, these microwave digestion systems save you lab space. With their integrated water coolers, Multiwave 7301 and 7501 save you even more space. There are multiple safety features, including redundant safety systems, fault-tolerant software, window shield, and drip cup, that make Multiwave 7101/7301/7501 the safest microwave digestion system of its kind on the market.

Communicative and compliant

Stay connected and up-to-date with your digestions with several smart features, including automated email notification of completed runs and events. Control the instruments via PC, smartphone, or tablet from a distance with VNC. Various standard methods are already available on the instruments, such as USP <232/233>, ICHQ3D, and European Pharmacopoeia 5.20. The software complies with CFR 21 part 11 and a comprehensive Pharma Qualification Documentation package is also available.
