MOD-8 rotor

The ETHOS EZ is easily converted into an open vessel digestion system with the MOD-8 rotor. The MOD-8 can hold up to 8 samples in 250mL glass or quartz vessels, with IR temperature control on every vessel for maximum reaction control and reproducibility. The entire rotor is composed of ultrapure PTFE, to minimize contamination. Each vessel is individually connected to an automated dispensing system, giving precise control over the addition of acid to each sample, and is fitted with a separately connected vacuum exhaust line, preventing any cross contamination.

The vessel exhaust lines are connected to the VAC-4000 high efficiency acid scrubber module, which collects and neutralizes acid vapors during the digestion run via an all-PTFE vacuum pump. A vacuum sensor built into the ETHOS EZ ensures microwave heating is only applied when the exhaust system is in operation. A water cooled PTFE condenser collects the condensed acid vapors into a PFA/PTFE collecting bottle (with up to 90% efficiency).

Typical application: Food and feeds, plus easy to digest organics.Can handle large sample weights (up to 2g).
