Lake Shore continuous flow cryostat transmission line

      these FHT-ST replace SuperTran or SuperTran-VP The high-efficiency transmission line of the low-temperature thermostat includes a built-in flow valve and a charcoal low-temperature pump . These transmission lines are optimized , It can be used with continuous flow low temperature thermostat , Not suitable for transporting large amounts of liquid helium .

      Three available models

      FHT-ST-25-56

      Continuous flow flexible liquid helium transmission line , be used for ST-500 Low temperature thermostat and based on ST-500 Probe table , Include ：

      20 Inches long ,0.25 Inch diameter conveying leg

      56 Inches long ,0.5 Inch diameter pull-out leg

      72 in Flexible sections and 0.06 in OD Internal helium line

      Pull out your legs 33 Vent at the end , To prevent Taconis Oscillate

       FHT-ST-38-56

        With all the others ST and STVP Low temperature thermostat （ Include ST-500-UC） Continuous flow flexible liquid helium transmission line used together , Include ：

      20 Inches long ,0.375 Inch diameter conveying leg

      56 Inches long ,0.5 Inch diameter pull-out leg

      72 in Flexible sections and 0.06 in OD Internal helium line

      Pull out your legs 33 Vent at the end , To prevent Taconis Oscillate

      FHT-ST- customized

      Customize SuperTran Line . Vacuum insulated flexible pipeline , Used to transfer liquid from storage Dewar bottle to equipment .

      all FHT-ST Specification of transmission line model

      General

      Bending radius of flexible part ： Minimum radius 12 Inch
      Including flow control valve , Used to control helium flow

      Traffic

      stay 5 psi Next , All transmission lines have been tested , The gas flow rate shall be at least 700 cc/min

      vacuum

      On all transmission line configurations NW25 Evacuation exit

      Recommended maintenance ： When you notice performance degradation , Use can achieve 10 -6 Torr The turbine pump evacuated the transmission line at least 12 Hours
      Be careful ：  The use of liquid nitrogen will make any vacuum drop more obvious , Need more frequent maintenance
