The unique MOD-8 Rotor

Simultaneous digestion of up to 8 samples

The MOD-8 rotor allows for the simultaneous open-vessel digestion of up to eight samples, in 250 ml glass or quartz vessels. The entire rotor is composed of ultra-pure, chemically inert PTFE and PP polymers, to minimize contamination.
The individual vessels are isolated, each with its own separately connected vacuum exhaust line, so there is no risk of cross contamination. Furthermore, each vessel is also individually connected to the automated dosing system, to ensure precise control over the distribution of acid to each sample.

The VAC-4000

High-efficiency acid scrubber module

The VAC-4000 performs exhaust and neutralization of acid vapours during the digestion run. A vacuum sensor built in to the START MOD unit ensures that proper exhaust of vapours is carried out.

1. Water-cooled PTFE condenser (recovers up to 90% of the acid vapors).
2. PFA/PTFE collecting bottle.
3. Neutralizing solution.
4. Acid-resistant, all-PTFE vacuum pump.

Maximum Flexibility

Open and closedvessel digestion in a single microwave unit !

The START system is the most flexible sa m p l e preparation platform available. Just by adding in-vessel temperature control and one of the pressure-capable rotors available from Milestone, it allows the chemist to perform both open and closed-vessel digestions in a single microwave unit.
Closed-vessel digestion allows chemists to work at higher temperatures and pressures, completing digestions faster and minimizing acid volume and sample contamination.
