This Welch DryFast Model 2025 self cleaning vacuum system is perfect for rotary evaporators. It is resistant to chemical attack, even from the most aggressive vapors and containg fluorinated plastics on all wetted surfaces.

Residue accumulation on the diaphragms & valves is reduced is reduced by a glass inlet separator that inhibits the ingesting of liquid & particulate contaminates which can impede performace. A gas ballast/vent switch acts to minimize vapor condensation inside the pump, and an automatic self-cleaning purge rids the pump of unwanted residue after every run. Very clean.
