The MMR modular microwave rotor

The MMR rotor is a device for conveniently heating materials in a microwave field under controlled vacuum conditions. When connected to an external vacuum supply (VAC-100 or VAC-2000 modules), and depending on the specific configuration, the MMR rotor can be used for vacuum assisted sarnple drying, acid removal, volume reduction, and solvent evaporation.
The MMR Rotor is a specially engineered fixture for accommodating either 8 or 12 microwave vessels. When inserted into the rotor, each vessel fits snugly into an adapter which seals the vessel for maximum vacuum or positive pressure applications. An adjustable valve with in-line filter provides positive air flow (from either the atmosphere or from an external inert gas supply), to assist and speed up the evaporation process. Each vessel is isolated from the others, so there is no cross contamination.
All rotor materials in contact with samples are made from TFM. Samples are processed in a clean, inert environment.
The unique design provides an idea1 platform for predigestion of large quantities of organic materials in near atmospheric conditions, followed by closed vessel digestion at elevated temperature.

The advantage of the Milestone MMR Technology

• Low-temperature, safe evaporation and concentration of acids and organic solvents.
• No sample transfer: evaporation takes place in the same vessel used for digestion.
• Evaporation of polar and non-polar organic solvents (e.g. Hexane) after organic solvent extraction.
• Rapid evaporation and concentration: 200 mL of acids (HC1, HF, HN03, etc.) evaporated in 30-90 minutes.
• Sample drying before extraction or digestion
• Available as an eight (8) or twelve (12) position fixture.
• Accommodates al1 Milestone's TFM vessels of al1 digestion rotors.
