Gas samplerHeliox series

vacuum for frozen products

A 3He sample-in-vacuum insert system compatible with 4He variable temperature inserts. • High performance • Easy to use • Quick sample change This sample-in-vacuum ³He refrigerator achieves less than 300 mK for more than 40 hrs and achieves 50 µW of cooling power at 350 mK for over 6 hrs. The HelioxVT uses a cold gas environment with a 50 mm access, therefore no need for a 1 K pot on the insert. This provides two key benefits: 1. The sample temperature range of a new or existing VTI can be extended below 280 mK 2. There is no liquid helium in the horizontal sample plane making the HelioxVT ideal for neutron or X-ray scattering experiments A complete system consists of: • HelioxVT insert • Temperature controller to operate the refrigerator • A variable temperature insert (VTI) with pump
