Parasitic 3He Insert for use with VTIs
Product Code: 3ICEVT20

A small, fast turnaround insert with 20mm outer diameter. Designed to be top-loaded into any manufacturer's variable temperature insert or continuous flow system (size permitting), and uses this insert's capability of reaching 1.5K in order to condense the self contained ³He charge.

Specification:

  • Base temperature <320 mK
  • Cooling power 50mW for >2 hours @ 350 mK
  • Diameter 20 mm
  • Length 350 mm
  • Hold time > 4 Hours

All specifications and dimensions can be adjusted to suit a user's needs. For more details please contact us.


Parasitic 3He Insert for use with VTI's Parasitic 3He Insert for use with VTI's and continuous flow cryostats
Product Code: 3ICEVT32

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

All specifications and dimensions can be adjusted to suit a user's needs. For more details please contact us.

Sample in Liquid 3He Insert
Product Code: 3ICETL

A top loading ³He system, the 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), ICEoxford® is 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 headroom.
