Labconco Welch Vacuum Pump, 158 L/min 115V or 133 L/min 230V,  PTFE Coated, 0.002 mBar Maximum Pressure

The Labconco Welch PTFE-Coated Vacuum Pump is a vacuum motor designed to withstand the most aggressive solvent vapors, acids, and chemical byproducts encountered during critical lyophilization processes, offering the ultimate resistance to corrosion. Featuring full PTFE (Teflon) internal coatings on all critical components within the vapor path, this heavy-duty, two-stage pump is fully protected against harsh chemicals—such as TFA, HCl, and acetonitrile—thereby preventing pitting on internal surfaces and premature mechanical failure. The unit delivers an impressive pumping capacity of 158 liters per minute (5.6 CFM) at 115V (60Hz) or 133 liters per minute (4.7 CFM) at 230V (50/60Hz), while also achieving an exceptionally deep ultimate vacuum of 0.002 mbar (1.5 Microns) to ensure flawless ice sublimation. Developed for pharmaceutical production lines, peptide synthesis, and agricultural technology research laboratories, this robust Labconco-Welch hybrid system maintains uncompromising high-vacuum stability, even under the most demanding chemical loads.

Features
