Features:

•  This model has an ergonomic design and is manufactured using numerically-controlled machine tools;
•  A specimen retraction function protects the specimen from blade damage;
•  A trim button allows for easy switching between trim and sectioning mode;
•  Includes a counting function for the number of sections and the total thickness;
•  The cryogenic refrigeration system utilizes a forced cooling structure. The refrigeration chamber, freezing shelf, blade holder, and specimen holder are cooled independently by a   German double compressor to enhance cooling  performance andincrease cooling speed.
•  Imported R404A non-CFC refrigerants that are environment-friendly;
•  Achieves the desirable sectioning temperature within 20 minutes after turning on the unit when using the fast cooling mode;
•  UV option enables surface disinfection of harmful bacteria, viruses, and spores by using 35 min after each use; It also has low-voltage DC shadowless lamp;
•  Semiconductor cooling function can be turned on and off;
•  Hearable and removable glass door;
•  Two defrosting modes: time defrosting and manual defrosting;
•  Microtome is outside of the refrigeration chamber to avoid the effect of heat-expansion and cold-contraction, thus minimizing the need for maintenance;
•  User-friendly intelligent operational interface is easy to learn and operate;
•  LCD screen displays the number of sections and the total thickness, section thickness, specimen retraction value, temperature setting, date, time, temperature and on/off timer are all included on the main display;
•  Auto sleep function results in longer compressor life: the cryo-chamber temperature automatically stays in a range of -1 to -9℃ under the sleep mode, and returns to the sectioning temperaturewithin 15 minutes after canceling the sleep mode;
•  Keyboard locking function to avoid accident misoperation;
•  A mechanical hand-wheel lock ensure safe chamber access, 16 position for locking;
•  The red bar on the blade holder covers the whole length of blade to protect the user and the push bar enables easy changing of the blade;
• A large-size quick-freezing shelf allows for the preparation of 17 specimens at the same time; Two holes for semiconductor refrigeration;
•  It has cleaning device, easy help customer to clean the unit;
•  Specimen Orientation: XY – 8°; Z–360° adjustable at any orientations to ensure preciseplacement;
•  Self-detection function for the temperature senor, can help to warn the failure on temperature senor.
