Welch freeze dryer vacuum systems provide deep vacuum and excellent chemical resistance in demanding applications. Based on direct-drive rotary vane technology, the Welch freeze dryer system has an integrated oil purification module that continually neutralizes oil pH and removes particulates. This side-mounted purification module also extends pump oil volume to 1.3 liters for superior contaminent dilution and longer oil life. Achieves vacuum levels down to 1×10-4 torr (0.1 micron) with flow of 173 L/min. Use Welch Gold Oil for maximum resistance to chemical attack. Handles harsh chemicals such as TFA, acetonitrile, HBr.
