Vacuum for Concentrators
Requirements:
- chemical resistance
- tolerance to condensates
- appropriate ultimate vacuum (depending on solvent)
Notices for Pumpchoosing:
| Ultimate vacuum down to 7 mbar: | For organic solvents and/or small amounts of water |
| Ultimate vacuum down to 1.5 mbar: | For water-based samples and low temperatures, e.g. DMF for T > 20 °C DMSO for T > 50 °C |
| Ultimate vacuum 10-1 mbar: | For quick “drying”, low temperature |
| Ultimate vacuum 10-3 mbar: | For high-boiling-point solvents to be evaporated at low temperature; drying with minimal residues |
