AST 550 Fully-automatic Cryostat Microtome

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 .

  • ● Freeze chamber minimum temperature : -35℃±2℃
    ● Freeze shelf minimum temperature:-45℃±5℃
    ● Lowest temperature of Peltier unit on freeze shelf:-55℃±5℃
    ● Lowest temperature of Peltier unit on Specimen Clamp:-50℃±5℃(working time of Peltier is 15 minutes.)
    ● Maximum specimen size:35×35mm
    ● Specimen vertical stroke:48±1mm
    ● Specimen horizontal stroke:15±0.2mm
