Parasitic ³He Insert for use with VTI’s
Product Code: ³ICE^VT32

A repeat of the VT20 except with a 32mm outer diameter for use in a larger VTI. Allows a larger sample space, potential for lower base temperatures and longer hold time. To load into a 2K or below environment.

Specification:

• Base Temperature <280 mK
• Cooling Power 50mW for >3 hours @ 350mK
• Diameter 32 mm
• Length 450 mm
• Hold Time > 4 Hours

For more details please call ICE. (all specs. and dimensions can be adjusted to suit users needs)

Sample in Liquid 3He Insert
Product Code: ³ICE^TL

Top Loading 3He System, sample on probe (^PRICE³) loads into the Insert, down to the liquid 3He or just above. Thermal contact to the cold source, surface of the liquid, can be done with the use of a thermal link made of copper, or a low eddy current cold finger if needed.

Fast and easy sample changing using a top loading probe (see ^PRICE³)ICE are able to offer a range of probe wiring and manipulator options. Please contact us with your requirements.

The system below compromises a special telescopic probe for use in labs with restricted head room.

Specification:

• Diameter To suit LHe Storage Dewar or Magnet System
• Length To suit System
• Base Temperature <260 mK for >50 hours (no heat load applied)
• Cooling Power <300 mK for >6 hours with 400mW applied heat load
