2 Ultra High Vacuum Flow Cryostats: Models RC-102 and RC-110 Cryo offers Models RC-102 and RC-110 Ultra High Vacuum continous flow cryostats, which feature rotatable Conflat interface flanges, your choice of 2.75, 4.50 or 4.62 etc.. Distance from chamber interface to cold finger can be selected to fit exactly your chamber. Constructions is all welded stainless steel with low vapor pressure silver brazed copper joints. The Model RC-110 offers the most advanced technology, resulting in better temperature stability. This is achieved with the addition of an internal metallized phase seperator which eliminates all temperature fluctuations. The Model RC-110-UHV has a heater assembly built on the end of the transfer line. This heater is not exposed to vacuum and is instantly accessible. (Note: The phase seperator is not installed in this model). An optional heater that mounts directly to the inside of the sample mount is available for the model RC102; this heater is accessible through a mini Conflat flange. The standard variable temperature continuous flow ultra high vacuum cryostat Models RC-102 and RC-110 feature the following: Operates with either Cryogen-10K Cryogenic Generator or Liquid Helium dewar Sample in ultra high vacuum (UHV) 4.5 inch rotateable conflat flange 1.00 inchy diameter copper sample mount with (6) #4-40 tapped holes on 0.75 diameter BC Vapor cooled radiation shield Hi Power (50 Ohm) heater installed on sample mount 0.62 inch O.D. helium vent/return port Temperature Range: Cooldown Time: Cooldown Consumption: Cryogen Consumption: Refrigeration Capacity: Temperature Stability: Orientation: Specifications (2-4) 1.33 inch mini conflat feedthrough ports (depending on style) Evacuation valve with NW25 interface flange Safety pressure relief on vacuum space Flexible stainless steel transfer line with flow control valve for operation with LHe dewar Silicon Diode Temperature Sesnor- bolt on style installed on sample mount < K (600 K optional) 10 minutes typical from 300 to 4.2 K (helium) 8 minutes typical from 300 to 77 K (nitrogen) 0.20 liters liquid helium from 300 to 4.2 K 0.55 liters/hour (helium) at 4.2 K for RC liters/hour (helium) at 4.2 K for RC-110 Lower at higher temperatures liters/hour (nitrogen) at 77 K Over 2 watts at 4.2 K 0.05 K for RC K for RC-110 Any Position
