Multiwave 7101/7301/7501: A Microwave Digestion System

When over 40 years of experience in pressurized acid digestion meets sophisticated microwave technology, a high-performance microwave digestion system is created. The Multiwave 7101/7301/7501 series takes performance to the next level, functioning at temperatures up to 300 °C and up to 199 bar.

This provides thorough digestion of all samples, including food, environmental, polymer, cosmetic, pharmaceutical, geological, chemical, and petrochemical samples, even in the same run. With a variety of accessories, consumables, and racks with up to 28 places, sample preparation has never been simpler.

Key Features

One Microwave Digestion System for All Samples

Digest a wide range of samples, including food, environmental, polymer, cosmetic, pharmaceutical, geological, chemical, and petrochemical ones, in one run using the same technique with Multiwave 7101/7301/7501. Elemental analysis is made easier by low blank values and low residual carbon content.

There is unlimited digestion performance due to the high temperature and pressure parameters (300 °C and 199 bar), and the magnetron output is automatically adjusted for reactive samples. Strong stirring facilitates the digestion of floating materials (optional).

Demanding Samples, Easy Digestion

The sample preparation workflow is revolutionized by the PDC (Pressurized Digestion Cavity):

• 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 transport the filled PTFE-TFM rack in a closed PTFE liner (<1 kg)
• Utilize software-guided, primarily automated opening and closing operations
• Count on automated pressurization, pressure release, and acid fume removal
• Pressure sealing of the vessels avoids cross-contamination

Microwave digestion systems provide ready-to-use techniques and customized application support, making method development easier than ever.

A Microwave Digestion System Fit for Any Analytical Task

Multiwave 7101/7301/7501 microwave digestion devices can handle various PTFE-TFM racks, allowing users to microwave digest up to 28 samples in a single run and up to 4 g of sample in a single position. A variety of vials are available.

Users can employ thin-walled quartz vials with low blank values or disposable borosilicate vials for everyday activities. PTFE-TFM vials are offered for specialized applications. When working with volatile analytes, use only sealed quartz vessels.

Space-Saving and Safe

Because of their small size, these microwave digestion devices save users lab space. The 7301 and 7501 Multiwaves save even more room since they include built-in water coolers. Multiple safety features, including fault-tolerant software, window shield, drip cup, and redundant safety systems, make Multiwave 7101/7301/7501 the safest microwave digestion system available.

Communicative and Compliant

With the help of several smart features, such as automated email notifications of completed runs and events, users can stay informed and connected with their digestions. Using VNC, users can remotely control the instruments from a PC, tablet, or smartphone.

The instruments can access several standard procedures, including European Pharmacopoeia 5.20, ICHQ3D, and USP <232/233>. In addition to being compliant with CFR 21 part 11, the software comes with a comprehensive package of Pharma Qualification Documentation.

Multiwave 7501: For Demanding Samples
