Laboratory Feedback
An excellent portable lab vacuum pump. We use it daily for Buchner filtration in our undergraduate teaching labs. The fact that it's oil-free means the students can't ruin it, and the 10 L/min flow rate is spot on for our needs.
Arrived next day in perfect condition. The included rubber hose is a nice touch, meaning we could set it up on the benchtop immediately. Very quiet operation compared to our old rotary vane pump.
As a QA/QC manager, I need reliable equipment that doesn't introduce contamination. This oil free diaphragm vacuum pump has been fantastic for our solvent filtration workflows. Highly recommend for any clean lab.
Solid little benchtop vacuum pump. It pulls a good vacuum at 0.075 MPa and is very compact. I knocked off one star just because the power cable could be slightly longer for our specific fume hood setup, but otherwise brilliant.
We were looking at a KNF pump but couldn't justify the cost for basic water filtration. This unit performs exactly as required for a fraction of the price. The UKCA certification gave our procurement team peace of mind.
Great maintenance-free vacuum pump. We use it for degassing small resin samples. It handles the job well, though you definitely need a catch pot in line to protect the diaphragm, which is standard practice anyway.
Technical FAQs
At OilFreeDia, we understand the daily frustrations faced by laboratory technicians, university research staff, and QA/QC analysts. Traditional rotary vane pumps are heavy, noisy, and require constant oil maintenance, while premium brands like Welch and KNF often stretch departmental budgets beyond reason for routine benchtop tasks.
We established OilFreeDia in the UK to bridge this gap. Our mission is to provide dependable, portable, and entirely oil-free diaphragm vacuum pumps that deliver consistent suction for everyday laboratory filtration. By focusing on essential performance metrics-such as a reliable 10 L/min flow rate and a 0.075 MPa vacuum capability-we ensure your workflows remain clean and uncontaminated.
Every pump we supply is UKCA and CE certified, rigorously tested for benchtop reliability, and dispatched directly from our UK warehouse. Whether you are outfitting a university teaching lab, a biotech startup, or a stringent quality control facility, OilFreeDia delivers the quiet, maintenance-free performance your scientific environment demands.
