Mini-pulse tube cooler
A low vibration cryogenic cooler providing a base temperature of below 50 K. This advanced pulse tube cooler has been developed with a 'split' configuration which allows the user to locate the cold tip remote from the Compressor, this significantly reduces the coupled micro-vibrations from the principal source of cooler vibration.
