The Entropy cryostat with Joule-Thomson stage offers continuous operation at temperatures around 1 K and a cooling power of a few Milliwatt.
Entropy JT cryostats are available as M- and L-series based on pulse-tube coolers with a cooling power of 0.5 W or 1.0 W at 4.2 K and various sample space.
JT stage with turbo pump:
- Base temperature: < 0.9 K
- Cooling power: a few mW at 1.0 K
JT stage with fore pump only:
- Base temperature: < 1.2 K
- Cooling power: a few mW at 1.3 K
Sample space at 4K:
- Ø 230 x 300 mm (M-series)
- Ø 300 x 400 mm (L-series)
- Or completely custom-made
