Helium-Nitrogen Dewar System

A matched set of Dewar's which can be ordered separately. Strip silvered.

EPR-ESR Helium Dewar System

This Dewar system is perfect for examinations at liquid helium temperatures for less than 60 minutes. May be ordered without stopcock, hand-pumped, and Heli-Dewar® processed to lessen helium permeation into the vacuum space by a factor of ten. Can be used with any instrument with a like chamber measurement.

Optical Studies Spherical Helium Dewar System

This spherical Dewar system features pure U.V. grade quartz windows and considers usage over long periods of time by allowing greater capacity with practical height consistency. Used primarily for Raman-spectroscopy and emission observations in semi-conductors at liquid helium temperatures and below. Additional window materials may be ordered upon request. These alternative materials will expand the capability of the system to a greater variety of testing and emission studies.
