Applications
Cryogenic Associates has long produced specialty vacuum vessels and cryostats for laboratory and research use, and compact units like the R-141212-75 are used in low-temperature physics and materials research — anywhere a sample needs to be held in a high vacuum environment, often at cryogenic temperatures achieved with liquid nitrogen or liquid helium. The optical viewport is a key feature for experiments that require spectroscopic, photometric, or visual observation of the sample without breaking vacuum. Typical applications include optical transmission and reflectance measurements at low temperatures, detector characterization, thin-film property studies, and semiconductor or photovoltaic material testing. The compact footprint makes it suitable for bench-top setups and small research cryostats.
This Cryogenic Associates R-141212-75 High Vacuum Container has been inspected and is in good used condition. The teal-painted body shows normal handling wear consistent with lab use, and all visible ports, fittings, and the optical viewport flange appear intact and undamaged. The valve assembly and side fittings are present and show no obvious damage. Please review our full photo set and contact us with any questions before purchasing.
