MBBC-N20106 Mössbauer N2 Cryostat

The Bath Cryostat MBBC-N20106 is designed for low-temperature Mössbauer spectroscopy with the Mössbauer source at ambient temperature. The cryostat is entirely made of stainless steel. A silicon diode DT-670 inside the cryostat is used as temperature sensor for the temperature controller TR-50.
Features
- Liquid nitrogen operation
- Temperature range from 56 K (by pumping off N2 gas) up to 330 K
- Temperature gradients less than 0.3 K (sample in N2 atmosphere)
- Long stand times due to low cooling liquid consumption
- Top-loading Mössbauer cryostat
- Easy sample change in cold condition
- Sample holder with a cylindrical hole of Ø = 20 mm for sample insert
