AST 500 Semi-automatic Cryostat Microtome

Product Description

Irtroduction:
AST **0 is a semi-automatic cryostat microtome whose specimen forward and backward movement are controlled by motor . So it can get high quality section and easily operated .

Designed Features:
●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 enviroment friendly refrigerant R**4.
● Adopt UV and O3 sterilize for *0 minutes every time.
● Peltier specimen clamp refrigeration may be turned on or off manually.
● Two defrosting methods: automatic and manual.
● 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 **0℃; After stopping this function, the temperature in freeze chamber will arrive to working temperature within *0 minutes.
● Control panel with locking function could avoid wrong operation.
● Handwheel locking function. 
● Wide freezing shelf can load 8 specimen cassettes simultaneously , and two of them are equipped with peltier to meet different temperature .
