Cryo Industries’ Sample in Vapor Variable Temperature Inserts (VTIs) fit into the bore of superconducting magnets and provide variable temperatures from <1.4 to 300 K. Samples are cooled by insertion into flowing helium gas exiting from the vaporizer (also known as the diffuser or heat exchanger).


A small amount of liquid helium is drawn from the magnet’s ‘bath’ into the vaporizer located at the bottom of the sample tube. The liquid helium is vaporized and heated to your pre-selected temperature. The gas enters the sample zone and the sample is cooled to temperature of the flowing gas.






Systems are available with choice of many standard sample tube sizes from 0.50" to greater than 4 or more inches. Inserts can be ordered to fit your existing magnet systems.
