Diaphragm Vacuum Pump
Oil-Free · Chemically Resistant · Rotovap-Ready
Nitrile Rubber Diaphragm · Oil-Free Operation · Adjustable Pressure · 130°C Overheat Auto-Shutoff · Continuous Duty
The vacuum pump that pairs with your rotary evaporator, filtration setup, or SPE manifold — without the maintenance headache of an oil-sealed pump and without the cross-contamination risk of a water aspirator. The RVP01 runs oil-free, produces clean vacuum from an anti-corrosive nitrile rubber diaphragm, and shuts down automatically at 130°C to protect the motor during long duty cycles. Built for continuous around-the-clock operation on the bench next to your rotovap.
Why Oil-Free Diaphragm Beats the Alternatives
The two common alternatives to a diaphragm vacuum pump both have problems. Oil-sealed rotary vane pumps pull a deeper vacuum, but they require oil changes, they back-stream oil vapor into your sample, and any aggressive solvent vapor that reaches the pump degrades the oil and kills the seals. Water aspirators are cheap but produce tons of contaminated wastewater, lose vacuum quality whenever water pressure drops, and can't pull below about 20 torr.
The RVP01's oil-free diaphragm design eliminates both categories of problem. No oil means zero back-streaming contamination into your sample, no fluid to change, and no disposal cost. The nitrile rubber diaphragm is durable against corrosive vapors — solvents, acids, alkalis — and the friction-free operation means no abrasion or heat buildup in the diaphragm itself. Combined with the automated cooling and exhaust system, the RVP01 runs continuously around the clock without the maintenance cycle of an oil pump.
Oil-Free Operation
No pump oil required — no back-streaming contamination, no oil changes, no disposal cost. Clean vacuum for rotovaps, filtration, and SPE manifolds.
Chemical-Resistant Diaphragm
Nitrile rubber diaphragm — durable, anti-corrosive, and friction-free in operation. Takes corrosive vapors without abrasion or heat buildup.
130°C Overheat Protection
Pump auto-shuts off at 130°C to prevent motor damage during long-duty operation. Resumes once the unit cools. Continuous around-the-clock capable.
Adjustable Pressure Valve
Adjustable pressure valve gives you manual control over the vacuum level — critical for rotovap work where the right vacuum depth controls evaporation rate and prevents bumping.
"No oil. No water. No contamination. No downtime." — The RVP01 is what a laboratory vacuum pump should be — clean, quiet, chemical-resistant, and ready to run on the same bench 24/7.

Ideal Applications
Rotary Evaporation
Primary vacuum source for rotovap systems — adjustable pressure valve controls evaporation rate precisely and prevents bumping on volatile solvents.
Filtration & SPE
Buchner-funnel filtration, SPE manifolds, gel drying, blotting post-electrophoresis — clean vacuum without aspirator water waste or oil contamination.
Corrosive-Vapor Work
Any application where chemical resistance and oil-free vacuum are the requirements — centrifugal evaporation, vacuum drying, and solvent-rich chemistry benches.
