    • It is designed under overall engineering and ergonomic concept. All the components are processed with computer numerical controlled machine.

    • Specimen retraction function, protects specimen from blade injury.

    • Trimming/Cutting button makes it easy to switch from trim and section mode.

    • Equip with counter to calculate total pieces and thickness.

    • Dual compressors, which are made in Germany, freeze the Cryostat chamber, freezing shelf, knife holder and specimen Clamp separate with pro-environment refrigerant R404.

    • Temperature can drop to working condition in 60 minutes after switching on.

    • Adopt to UVC sterilize for 35 minuts every time.

    • Peltier may be on or off manually.

    • Heated, removable sliding window.

    • Two defrost methods: definite time and manual.

    • The high-precision microtome is enclosed outside the cryostat chamber to protect it from thermal expansion and contraction and keep minimum service and maintenance.

    • Self-explanatory symbols for all functions and displays, easy to learn and operate.

    • LCD screen can display date such as sample travel, thickness, function controlling ,day, time, temperature,
      timed on/off and so on.

    • Stand by mode, after initializing, the temperature in cryostat chamber can be controlled between -4 C and -9 C by computer automatically; when stop initializing, the temperature in freeze chamber will arrive to working temperature within 10 minutes.

    • Control panel with locking function to avoid wrong operation.

    • Handwheel locking.

    • Sensor self-diagnosis function.

    • Wide freezing shelf may put 10 specimen cassettes.
