The CryoStar NX50 Cryostat follows in the footsteps of the popular CryoStar NX70 Cryostat by offering standard features well suited to the routine clinical histology laboratory.

The NX50 and NX70 utilize a rapid response cooling system that actively cools all areas of the cryochamber that come in contact with the sample, including the specimen clamp, cryobar and blade. The result is precise temperature control and half the energy consumption of other routine cryostats. Low energy LED lighting with user-adjustable intensity is also included.

Ergonomic/Safety features

  • Touch screen interface and intuitive software allows the user to view and adjust the following parameters: temperature, section thickness, remaining blade holder travel, sectioning and trimming thickness and all other instrument settings
  • Standby mode for energy savings and noise reduction
  • “Green instrument” 0.30kW/hr measured during a regular day running mode (7.2kW/day)
  • Specimen retraction
  • Optional Height adjustment design allows the user to work in either a standing or sitting position
  • Body contoured design positions the user closer to the chamber and the microtome
  • Optional on-demand Cold D disinfection system
  • Optional Vacutome system collects and contains sectioning waste within a filter bag
  • Manual handwheel lock secures the upper position of specimen head
