Angstrom ONXY-3 3" diameter electron emission cathode for vacuum laboratory applications.
The Angstrom ONXY-3 Cathode is a 3-inch diameter electron emission cathode designed for use in laboratory vacuum devices. This component serves as a critical part of electron beam generation systems widely used in applications such as molecular diagnostics, bioprocessing instrumentation, and biomedical engineering research.
Key features include:
This cathode is fundamental in setups requiring precise electron beam generation in fields such as molecular cloning workflows and live-cell imaging where vacuum tube components ensure optimal performance. For detailed compatibility and technical specifications, further consultation with the manufacturer or supplier is recommended.
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.
