The Limpsfield LPN3/2051 is a Natural Gas Burner with an energy output of 2051 KW/hr (7.0 MBtu/hr), designed for efficient and precise heating applications.

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.
