Efficient, oil-free vacuum pump ideal for evaporation and distillation tasks.
The KNF N 920 KT.29.18 G diaphragm vacuum pump is a high-performance laboratory device engineered to provide consistent and efficient vacuum operations. It boasts a maximum flow rate of 21 liters per minute and achieves an ultimate vacuum of 2 mbar (abs.). Operating at a maximum pressure of 0.5 bar (rel.), this pump is suitable for fluid temperatures ranging from 5 to 40°C. Constructed with FFPM valve material, a PTFE-coated membrane, and a PPS pump head, this pump is tailored for corrosion resistance.
Applications of this vacuum pump include use with rotary evaporators, distillation processes, centrifugal concentrators, and fluid aspiration, making it a versatile addition to any lab. Its operation is entirely oil-free, ensuring clean processes, while its high suction speed excels in the low vacuum range. With adjustable speed control, quiet operation, and a maintenance-free design, this pump is both user-friendly and reliable.
The package includes a power cord, operator's guide, manufacturer's documentation, and a 1-year warranty. For additional details and accessories, download the product data sheet. If assistance is needed in selecting the appropriate vacuum pump, consult KNF's comprehensive guides on laboratory vacuum pumps.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
