Description of AST550 Fully-automatic Microtome Cryostat
- It is designed under engineering and ergonomic concepts. All the components are processed by computer numerical control.
- Retraction function prevents specimen damage from blade.
- Total thickness calculation.
- Low temperature refrigeration system with environment friendly refrigerant R404.
- Adopt UV and O3 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 -1℃ and – 10℃; After stopping this function, the temperature in freeze chamber will rise to working temperature within 30 minutes.
- Control panel with locking function could avoid faulty operation.
- Handwheel locking function.
- Wide freezing shelf load 8 specimen cassettes simultaneously, and two of them are equipped with peltier to meet different temperatures.
