Welch Freeze Dryer Pump System
Fast solvent sublimation
Durable, chemical resistant performance
Portable and powerful
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 1x10-4 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.
