The Leica CM3050 S is an advanced cryostat system designed to enhance user comfort and to meet the demands of cryosectioning in a broad range of research applications. Featuring excellent safety standards for practically all types of cryosectioning applications, the CM3050 S is the perfect solution for precise specimen orientation and output quality.

Among the many superior features of the CM3050 S system is its powerful, quick freezing shelf. The actively cooled quick freezing shelf (-45 °C) with its heat extractor allows extremely fast specimen freezing. A truly flexible system, this Leica cryostat allows for hydraulic cabinet height adjustment to give the user freedom to work comfortably while sitting or standing. All functional keys are easily accessible in any position.

The Leica CM3050 S cryostat provides the most important settings such as cutting speed range, cryo chamber and specimen temperature, defrost time and duration, coarse feed and object temperature can be conveniently and accurately preselected by simply pushing a button. A new feature that has been added is the section thickness selection from outside the cryochamber – now conveniently located at the control panel.
