Welch BTpro70
Welch’s BTpro vacuum pump series has a flow and vacuum level to provide fast performance for your size of rotary evaporator, glass reactor, purge oven, or winterization filtration apparatus.
These chemical duty PTFE diaphragm pumps are oil-free. The pumping action and deep vacuum comes from the movement of PTFE diaphragms within PTFE heads. All wetted services in the flow path are made of fluoroplastic making the BTpro pump highly chemically resistant. As a result, the BTpro vacuum pump series is near-zero maintenance. A cold trap placed in-line with BTpro pump is needed if terpenes are part of the flow path.
The BTpro40 and BTpro70 models employ patented valve and diaphragm technology that generates a deep 15 Torr vacuum pressure with each PTFE head. In addition, both pump models have built-in tuneable vacuum to control evaporation rate. The tunable vacuum adjustment can also be used to stop accidental bumping/foaming.
