Rotary Evaporator
 |
The rotary evaporator is used to remove solvent from reaction mixtures. The rotary evaporator uses heat, vacuum and expanded surface area for rapid, but gentle evaporation. To select the perfect pump for a rotary evaporator process requires understanding the partial pressure of the solvents to be evaporated, chemical compatibility and flow rates sufficient for a rapid process.. Chemtech can assist you in selecting the rotary evaporator and pump match to best suit your needs. Matching the vacuum pump to your needs will be very important for trouble free operation of your system. Please contact your Chemtech Scientific expert for the best selection. |
