AST 550 is a fully-automatic cryostat microtome whose specimen forward and backward movement are controlled by motor . So it can get high quality section and easily operated .
● 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 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 arrive to working temperature within 30 minutes.
● Control panel with locking function could avoid wrong operation.
● Handwheel locking function.
● Wide freezing shelf load 8 specimen cassettes simultaneously ,and two of them are equipped with peltier to meet different temperature .
