Robust Welch Chemstar C426V1 vacuum pump with 3/4 HP motor, 208-230/460 V, 60 Hz, thermally protected for lab use.
The Welch Chemstar C426V1 vacuum pump is a robust and reliable pump optimized for laboratory and industrial vacuum applications, including biotechnology workflows such as molecular diagnostics and bioprocessing. Equipped with a 3/4 HP Century AC motor, it operates on a voltage range of 208-230/460 V at 60 Hz frequency, ensuring stable performance. The pump is thermally protected and pre-lubricated, eliminating the need for additional maintenance lubrication and enhancing operational reliability in continuous duty cycles.
Key technical features include:
This vacuum pump is essential for applications requiring consistent vacuum pressure such as live-cell imaging preparation, synthetic biology setups, and analytical instrumentation degassing. Its rugged construction and stable electrical characteristics make it widely adopted in molecular biology research and clinical diagnostics environments. The pump’s reliable vacuum source also supports workflows in biopharmaceutical production pipelines and biomanufacturing processes that demand steady suction and contamination-free operation.
Designed for use in laboratory settings requiring durable vacuum equipment, the Welch Chemstar C426V1 is an efficient choice for scientists and researchers working in cell imaging, fluorescence analysis, and neuroimaging 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.
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.
