Original Heidolph ventilation valve for Hei-VAP benchtop rotary evaporators and vacuum pressure equalization.
The Heidolph ventilation valve 11-002-591-37-0 is an original spare part for the Heidolph Hei-VAP benchtop rotary evaporator. It provides controlled ventilation of the vacuum system after evaporation, supporting pressure equalization and helping protect the system from vacuum-related backlash.
This rotary evaporator accessory is suitable for laboratory evaporation, solvent recovery, biotechnology workflows, and other applications requiring controlled vacuum release.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
