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 materials – 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:

• Weigh your samples into vials
• Add digestion reagents and cover the vials with plug-on caps
• Load the vials into a rack and put it into the PTFE-TFM liner
• Safely transfer the closed liner (<1 kg) into the PDC
• Use software-guided, semi-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 41 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 for hydrofluoric acid applications. Use sealed quartz vessels, when working with very volatile analytes.

Space-saving and safe

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

Communicative and compliant

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