Description

The Welch Self-Cleaning Dry Vacuum System manufactured by Cole-Parmer is suitable for use with rotary evaporator. This two-stage flexible diaphragm pump is resistant to corrosive gases and the accumulation of solid residues or liquids on the diaphragm. The glass inlet separator captures the liquid and particles in the steam before the steam enters the pump. When pumping a large amount of steam, you only need to adjust the gas ballast or exhaust switch to suppress the condensation of steam inside the pump head.
