◎ The MH1800 has been designed with all ergonomic considerations in mind. All the components are processed with computer controlled numerical machining centers

◎     The specimen retraction function, protects the specimen from blade damage.

◎     Electronic Trim/Cut function makes it easy to switch from trim and section mode

◎     The MH1800 is equipped with a rotation counter function in order to calculate total section pieces and total thickness.

◎     The refrigeration system contains one compressor, which is made in , and freezes the cryostat chamber and shelf separate with environmentally safe refrigerant (R404)

◎     The chamber temperature can drop to working condition within 60 minutes after switching the unit on.

◎     Sterilization can be accomplished with UV light within 35 minutes after use. 

◎     Peltier may be switched on or off manually.

◎     Unit contains heated, removable sliding window.

◎     Unit contains 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 make the unit easy to learn and operate.

◎     LED screen can display data such as sample travel, thickness, function control, day, time, temperature and time on/off.

◎     Stand by mode, after initialization, the temperature in cryostat chamber can be controlled between -4℃ an -9℃ by computer automatically; once stopped initializing, the temperature in freeze chamber will arrive to working temperature within 10 minutes

◎     Control panel with locking function to avoid improper operation.

◎     Multi position handwheel lock.

◎     Sensor self-diagnosis function.

◎     Wide freezing shelf may put 10 specimen cassettes

◎     Specimen orientation on X/Y axes 8°and specimen rotation on Z axes 360°
