The chemically resistant LABOPORT diaphragm pumps are single-head and double-head dry-running devices used in a wide range of laboratory applications. They transfer and pump down without contamination. The heart of these very compact pumps is a KNF structured diaphragm. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm. The pumps are available with various flow path material options, flow rates, and ultimate vacuum levels.

"We purchased a number of these pumps for rotary evaporation of organic solvents. The pump are incredible durable and stand up to endless hours of abuse. They are also easy to maintain. KNF serviced some older pumps we had and they are as good as new."
