Definition of cryostat in English:



  • 1An apparatus for maintaining a very low temperature.

    • ‘Temperature was controlled by a gold-chromel thermocouple at the base of the cryostat and monitored with an identical thermocouple immersed directly in the sample (approximately 3 mm above the illuminated volume) during measurement.’
    • ‘To achieve temperatures of 77 K, we used a liquid nitrogen cryostat.’
    • ‘The spectrometer was modified to incorporate an Oxford cryostat at the sample compartment.’
    • ‘The sample was then mounted in a cryostat and cooled down rapidly.’
    • ‘Using cyromolds that have been chilled on dry ice or in the cryostat, use a layer of OCT embeding compound and press the tissue to the bottom of the flat surface.’
    1. 1.1 An apparatus for taking very fine slices of tissue while it is kept very cold.
      • ‘The cross section of the cervical tissue containing both the epithelium and stroma was exposed by shaving off layers of the embedding medium and tissue using a cryostat.’
      • ‘A post-doc was working on a cryostat, cutting microscopically thin sections of tissue.’
      • ‘Smooth muscle area was determined in 8-m-thick cryostat lung sections.’
      • ‘Twelve-micrometer serial sections of head or body were cut in a cryostat at - 18°.’
      • ‘Heads and bodies of wild-type flies were cut into 12-m sections using a cryostat and hybridized with the relevant probe.’
