Rotary microtome cryostat AST 550

automatic

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 .
