Leica CM3050S Cryostat


The Leica CM3050S Cryostat is suitable for the demanding needs of cryosectioning in biomedical, neuro-anatomical and pharmaceutical research. The Leica CM3050 S cryostat features superior user comfort with excellent safety standards for practically all types of cryosectioning applications. The precise specimen orientation and the specimen feed system guarantees reproducible, thin, serial sections of maximum quality, especially when working with delicate specimens. The precise specimen orientation and the specimen feed system via step motor allow reproducible thin sections of maximum quality when working with large specimen.


The Leica CM3050S cryostat is very versatile and easy to operate. Its key features include:
  • Precision – The precise specimen orientation and the specimen feed system via step motor allow reproducible think sections of maximum quality when working with large specimens.
  • Efficiency – Highly efficient insulating materials to enhance durability of the refrigerating system and support stable cryochamber temperatures; independent refrigeration system ensures powerful specimen temperature control and rapid temperature changes.
  • Spacious – The easily accessible cryochamber provides large space for convenient handling and specimen storage.
  • Functional – The lateral displacement feature of the knife holder CE for disposable blades allows the use of the entire blade.
  • Convenient – A preselected number of sections can be carried out in both sectioning and trimming mode with the reverse section counter. Section thickness totalizer and counter with reset button facilitates target preparation, promoting fast trimming between levels.
