Workhorse of the Research Laboratory

Clean, oil-free diaphragm pumps are the the workhorse of the research laboratory because PTFE chemical resistant diaphragms stand up to many aggressive compounds. Diaphragm pumps can be used for a variety of purposes and work on vacuum ovens, rotary evaporators, winterization/filtration systems, short-path distillation, freeze dryers, glove boxes, etc. Cascade Sciences carries Welch diaphragm pumps for a variety of applications.

To prolong the life of your diaphragm pump perform regular maintenance. Regularly replace the diaphragm and conduct pump rebuilds.
