Transfer tubes play an important part in the overall helium consumption and base temperature capability of helium cooled cryostats.
Oxford Instruments Low Loss Transfer tubes (LLT) allow for the lowest helium consumption of cryostats. Our LLT range use the cold gas exiting the cryostat to cool the shields surrounding the incoming liquid within the transfer tube. As a result, the consumption of our cryostats is the lowest on the market, dramatically reducing your running costs.
There are two types of transfer tubes:
LLT600: Transfer tube for horizontal feed cryostats
LLT700: Transfer tube for vertical feed cryostats
There is also an automated needle valve control option (model LLT650 and LLT750): with this option the temperature controller is able to drive the motorised needle valve, resulting in more stable temperature control and lower cryogen consumption.
