4 mL vacuum-insulated borosilicate glass Dewar for small-volume cryogenic liquid transport.
The KGW Isotherm Type 29 B is a compact 4 mL cylindrical transport Dewar designed for the storage and transport of small quantities of cryogenic liquids, including liquid nitrogen, oxygen, and argon. It is suitable for laboratory research, industrial handling, and precise cryogenic applications requiring minimal sample volumes.
The vacuum-insulated double-wall construction provides thermal isolation in a compact format. The carrying ring supports secure handling during transport. This cryogenic Dewar flask may be used in biotechnology, molecular biology, bioprocessing, and other laboratory workflows involving small-volume cryogenic liquids.
The vessel is described as being in very good condition, with no cracks or chips reported. The vacuum insulation is stated to be intact and functional.
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.
