• Semi-automatic Cryostat Microtome

Semi-automatic Cryostat Microtome


ST 500 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. 

 

  • 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 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: 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 -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 can load 8 specimen cassettes simultaneously , and two of them are equipped with peltier to meet different temperature.
