Model AST550 -Fully-automatic Cryostat Microtome
It is designed under overall engineering and ergonomic concept. All the components are processed by computer numerical controlled machine. Retraction function prevents specimen damage from blade . Total thickness calculation. The low temperature refrigeration system with environment friendly refrigerant R404. Adopt UV and 03 sterilize for 30 minutes every time. Peltier specimen clamp refrigeration may be turned on or off manually. Two defrosting methods: manual and automatic. Two running ways: manual and automatic. Emergency stop function : Press the red button to stop running when any emergency happens. The high precision unit is enclosed outside the cryostat chamber to prevent it from thermal expansion and contraction, and keep minimum maintenance requirement.
- Artificial intelligent interface is easy for user to learn and operate.
- LCD screen can display all information including thickness, thickness sum. controlling time, temperature, timed on/off and so on.
- Sleep Function. After activating this function, the temperature in cryostat chamber can be kept between -1BC and -10°C; After stopping this function, the temperature in freeze chamber will arrive to working temperature within 30 minutes.
- Control panel with locking function could avoid wrong operation.
- Handwheel locking function.
