Stainless steel female 1/4"NPT to NW25 vacuum pipe adapter for laboratory vacuum pump systems.
The Welch 506122 vacuum pipe adapter is a stainless steel female 1/4" NPT fitting designed to interface with ISO NW25 vacuum flanges. Primarily used as a laboratory vacuum system accessory, it enables secure and leak-resistant connections between vacuum pumps and ancillary vacuum components. This adapter is compatible with common vacuum pumps such as Welch and Edwards, making it invaluable in setups requiring precision vacuum line assemblies.
Key features include:
Ideal for researchers and laboratory technicians working in vacuum technology, this adapter is a fundamental component in biomanufacturing vacuum systems and is widely used in disciplines requiring controlled vacuum environments, such as live-cell imaging sample preparation and fluorescence analysis instrumentation.
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.
