Liquid Helium, Liquid Nitrogen Research Dewars

Research Dewars

Janis Research designs and manufactures a line of superior quality research dewars. With a wide range of styles and options available, there is sure to be a dewar to suit your application.

Dewars are available with a demountable bottom flange for the easy addition of an optical or non-optical tail set. If this option is not required, then dewars are available with a welded bottom flange. All joints are leak-checked warm and cold to ensure that Janis Research's standard of high quality is maintained.

Both liquid nitrogen and vapor-shielded dewars are available, and all dewars have been designed to minimize liquid helium consumption. Mounting flanges are available, with the style of flange depending on the size of the dewar.
