MB-SPS Solvent Purification System

The MBraun Solvent Purification System (SPS) (M.Braun, Inc) removes oxygen and moisture from organic solvents. To remove oxygen from the HPLC grade solvent, the solvent reservoir is purged by the compressed Nitrogen of 99.99% purity. The moisture is removed when the solvent is forced through the circuit of two gas tight stainless steel dessicant columns. Purified solvent which is free of oxygen and moisture is dispensed into a collection vessel under anaerobic conditions by means of the valves located on the front of the system.

Dispensing solvent is a three step process. On the first step, the collection vessel is evacuated to create an anaerobic environment. The second step is the actual dispensing. On the third step the solvent line is cleaned, so solvent does not remain stored there while the system is not in use.

The following solvents are available:

  • Acetonitrile
  • Benzene
  • Chlorobenzene
  • Chloroform
  • Dichloromethane
  • Diethyl ether
  • Dimethyl sulfoxide
  • Hexane
  • Pentane
  • Tetrahydrofuran
  • Toluene

The solvent purification system is located in the room LS 1141.
