Thermo Scientific Viton O-ring seals, part numbers 75003020 and 15894907, supplied as sets of 2 (6x).
Thermo Scientific Viton O-Rings, part numbers 75003020 and 15894907, are replacement sealing components for compatible laboratory instruments and systems.
These laboratory equipment spare parts are suitable for maintenance and seal replacement in research, biotechnology, and other laboratory workflows. Exact compatibility should be verified against the equipment model and service documentation before installation.
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.
