Models 2034 / 2044 Research Two stage PTFE diaphragm pumps provide tunable vacuum to 9 torr – perfect for evaporation of solvents with atmospheric boiling points to 110 °C. Select Model 2044 (35 l/min) for evaporations up to 10 L flask.

• Powerful vacuum pumps for rotary evaporators • Tunable vacuum to control evaporation rate • 2 torr (2.7 mbar) models strip DMF fast at 35 °C 9 torr (12 mbar) models strip most common solvents • Rugged chemical duty PTFE and fluorinated   plastic construction


Tunable Vacuum For Fine Evaporation PTFE dry vacuum pumps for rotary evaporators include essential features to ensure efficient rotary evaporation. The DryFast tunable vacuum adjustment allows the user to optimize the vacuum for the solvent being evaporated - see Application Note below. The tunable vacuum adjustment can also be used to stop accidental bumping/foaming.


Use 9 torr (12 mbar) DryFast models for common solvent  evaporations. DryFast Ultra models offer 2 torr (2.7 mbar)  ultimate vacuum to strip DMF fast along with other high boiling point and low boiling point solvents. The rugged low maintenance oil free pumps have PTFE heads, perfluoroelastomer valves, and fluorinated plastic wetted surfaces, making DryFast a durable choice for solvent, acidic and basic vapors.
