Similar to the Welch 2052, the Welch BTpro100 offers additional flow and vacuum level adjustments to control your vacauum, as well as patented valve and diaphargm design that allows for deep vacuum level. Vacuum control allows this pump to be used more versatilely for preventing pumping and foaming during distillation, rotovaping, and more.
the Welch 2052 chemical-resistant diaphragm pump is the workhorse of the laboratory! The four-head diaphragm pulls a deep, consistent vacuum while the oil-free design provides clean operation and easy maintenance.
Welch pumps are made in Germany, include 3' of 3/8" high quality silicon vacuum tubing, and are backed by a 1-year warranty.
Maintenance is as easy as allowing the pump to cycle ethanol through itself. Replacement diagrams are also available and an easy job that can be done in house.
