Testing chambers are connected to a bulk supply source of Liquid Nitrogen (LN2). The submersion chamber is flooded with LN2. A chamber controller perpetually keeps the sample testing chamber flooded and monitors and records the temperature and liquid (Nitrogen) level in the sample testing chamber.

For “internal” vacuum testing of components in the -196.7 submersion chambers: you will need to fabricate a container with a ¼” or ½” internally or externally threaded connection point. If you want us to do a dry nitrogen purge on your sample, then you would need to fabricate a tube with a threaded fitting at both ends. If you like we can monitor the “internal” vacuum inside the sealed sampled to see if pressure is leaking through the sample wall into the sealed container. This chamber is permanently on line, and there is no time limit to how long test subjects can be in submerged in Liquid Nitrogen. We could can leave samples in for months or even years if needed.
