Disposable filter removes oil mist and odor from vacuum pump exhaust May be exhausted into work area without ducting Includes filter assembly,...

Use Welch ProBoost in conjunction with a backing pump like the CRVpro to get deeper vacuum and higher flow. High Vacuum to 10 - 5 torr Use with high vacuum and Schlenk lines Employs air cooled diffusion pump Easy Attachment to backing pump Welch ProBoost is an air-cooled gas jet pump (commonly...

High contamination tolerance Vital parts corrosion resistant Reduced frictional wear Nitrogen purge standard Easy attachment of accessories Recommended for use with gases such as HCl, HBr, Br_2, Cl₂, O₃, HOAC, F₃CC0₂H, CH₂0,...

The Laboport® vacuum pumps feature a solid-PTFE pump head, FFPM valves, and PTFE-coated diaphragm for excellent protection against the most aggressive corrosives. Easily transfer and evacuate most laboratory gases and vapors without contamination. The pumps are ideal for filtration,  with...

Humboldt Aspirator Filter Pumps offer excellent performance for vacuum filtrations under both high and low water pressure conditions. The pumps feature a ball-type, positive-action valve in the suction tube which prevents water backflow if the pressure is reduced.

Combination vacuum pumps integrate a high performance rotary vane pump with a chemical-resistant diaphragm pump to create a low maintenance, longer-lasting pump. The diaphragm pump removes the condensable vapors in the rotary vane pump before they can contaminate the oil, thus extending the life of...

Microsart Membrane Pumps: Microsart maxi.vac and mini.vac are electric neoprene membrane pumps (oil and maintenance free) with a low noise level and with precise control.

Standard Duty Handy Welch pump is perfect for basic lab vacuum operations. Dry or aqueous vapors only, portable, vacuum or pressure, 115V

Scroll Vacuum Pumps are dry pumps that use two spiral scrolls to compress air and vapors and move them toward the exhaust. While they can have higher up-front costs, the lifetime operation costs are much lower because they don’t require oil and very little maintenance is needed. It is...
