Exceptional Sectioning Quality

Stable, actively cooled knife holder delivers homogenous and consistent section thickness

Specimen head moves in vertical orientation only, for improved cutting accuracy

Rapid response temperature controlled object head maintains accurate specimen temperature to deliver high quality sections

18 position cryobar with additional fast freeze station rapidly cools specimens to -57°C ± 3°C (-71°F ±5.4°F) maintaining tissue morphology by restricting ice crystal


Optional vacutome aids in delivering high-quality sections by stretching the sections to remove wrinkles

Superior Section Quality

Achieved by minimizing vibration to deliver a smooth movement of the specimen across the blade.

Stable blade holder for mounting blade

Dedicated low and high-profile blade holders

Steady controlled horizontal advance of blade to specimen

Convenience and Ease of Use

Touch screen interface with intuitive software is the single point of control for the

Thermo Scientific™ CryoStar™ NX50 cryostat delivering quick and streamlined


Standby mode reduces energy consumption and background noise

Choice of immediate or scheduled defrost cycle

Optional vacutome cleaning mode and hose extension supports safe and speedy

removal of debris and sectioning waste

1 Litre disinfectant reservoir sufficient for up to 13 Sanosil® disinfection cycles

User Comfort

Body contoured design positions the user closer to the chamber maintaining

comfortable posture during times of heavy use

Optional motorized height adjustment allows each Operator to customize the CryoStar

NX50 height to suit their needs and comfort level whether seated or standing

Large open work chamber with adaptable LED directed lighting for enhanced visibility

Light touch handwheel requires minimal force to operate, limiting associated repetitive motion discomfort

Operator Safety

Manual handwheel lock secures the position of the specimen head

Optional proprietary Cold-D disinfection of the cryochamber which has been certified

as an effective method against an extensive range of biological pathogens

Magnetic blade transfer tool supports safe removal of the blade from the holder,

reducing risk of injury

Protective blade guard shields the operator’s hands from the blade

Optional vacutome collects and contains sectioning waste within filter bag
