The Welch DryFast Ultra Pump (PTFE Diaphragm) is made from protected internal components, including Kalrez valves, PTFE heads and diaphragm, fluorinated plastics, and more.

All parts are oil-free, which sets this unit apart from others in the class. This unit’s small footprint makes it a fantastic fit for any lab. Welch DryFast Ultra Pump units have an Advanced Vapor Management System which allows for the faster evaporation of organics.

An easy to use, no-nonsense vacuum pump.

The Welch DryFast Ultra’s two-head diaphragm design makes it easier than ever to connect and disconnect vacuum lines. The result is a pump that’s highly effective and still very easy to use.

Varying flow rates, adjustable vacuum knob.

These pumps come in varying flow rates, all the way up to 70 L/min. They also come standard with an adjustable vacuum knob, giving the user control over vacuum pull all the way down to 2 Torr. This family of pumps has a wide variety of uses, such as distillation, rotary evaporation, vacuum ovens, concentration, and more.

Note: Welch DryFast Ultra Pumps work especially well at removing high boiling-point compounds and solvents such as Dimethylformamide.
