MBBC-N20106
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
