LS-2900 Semi-automatic Cryostat Microtome

Design Features

◎     It is designed under overall engineering and ergonomic concept. All the components are processed with computer numerical controlled machine

◎     Specimen retraction function, protects specimen from blade injury

◎     Trimming/Cutting button makes it easy to switch from trim and section mode

◎     Equip with counter to calculate total pieces and thickness.

◎     In the mandatory refrigeration structure, one compressor, which is made in Germany, freezes the cryostat chamber and shelf separate with pro-environment refrigerant R404

◎     Temperature can drop to working condition in 60 minutes after switching on.

◎     Adopt to UVC sterilize for 35 minutes every time. 

◎     Peltier may be on or off manually.

◎     Heated, removable sliding window.

◎     Two defrost methods: definite time and manual

◎     The high-precision microtome is enclosed outside the cryostat chamber to protect it from thermal expansion and contraction and keep minimum service and maintenance.

◎     Self-explanatory symbols for all functions and displays, easy to learn and operate.

◎     LED screen can display data such as sample travel, thickness, function controlling, day, time, temperature, timed on/off and so on

◎     Stand by mode, after initializing, the temperature in cryostat chamber can be controlled between -4℃ an -9℃ by computer automatically; when stop initializing, the temperature in freeze chamber will arrive to working temperature within 10 minutes

◎     Control panel with locking function to avoid wrong operation.

◎     Handwheel locking

◎     Sensor self-diagnosis function.
