Traditional VTI Systems

Variable Temperature Insert Product Code: ⁴ICE

These Variable Temperature Inserts (VTI) operate in a transport dewar or magnet cryostat picking up Helium from within this bath temperatures of below 1.5K can be achieved together with high cooling powers Both are top loading with a variety of Top loading sample holders available.

We have also undertaken many custom VTI's such as a 2" sample space VTI to fit a 3" cold bore magnet

Specification:

• Temperature Range 1.5 - 300 K with 30 mm sample space
• Temperature Range 1.5 - 200 K with 37 mm sample space
• Stability ±0.1 K
• Base Temperature 1.5 K
• Sample Change Time 5 min
