Our research is concerned with finding and synthesizing novel therapeutics for various cancers. We routinely extract compounds in corrosive, organic solvents and pump them under vacuum to obtain the pure molecules. As such, a high performance pump is an essential tool. Previously, we used oil-lubricated pumps, but these needed significant amounts of maintenance due to corrosive solvents mixing with the oil. We had heard that KNF manufactured a chemically-resistant pump that needed less maintenance and that held the vacuum seal better. After two years, the LABOPORT® pumps have proved very reliable. In fact, they have lasted three times longer than any other pump we have used.
