Leica CM3050 S – Cryostat

Processing multiple specimen and performing serial cuts can result in high section numbers. Nevertheless, reproducibility can’t be compromised. Permanent attention to detail and many hours in front of the cryostat can be exhausting for the user. The Leica CM3050 S cryostat is designed to help with exactly these time-consuming jobs.

The low working height and available knee space of the Leica CM3050 S cryostat allow the user to work comfortably while sitting. Motorized drive and section counter improve productivity for multiple serial sections.

  • Precision Sectioning

When working with large samples, accurate specimen orientation and feed are crucial. The precise specimen orientation system with zero position provides for x/y adjustment of up to 8°. The specimen feed system with 25mm horizontal feed allows for reproducible thin sections.

  • Precision Cooling

An independent refrigeration system for the object head provides for temperature changes and efficient specimen temperature control to adjust for difficult samples such as brain or fatty tissue.

  • Stay Organized

With critical items at hand, you can focus on your sectioning job. Freezing stage and tool tray in a large cryochamber, as well as an easily accessible storage area on top of the cryostat help you staying organized. The motor drive with foot-pedal enables you to have both hands free for sample handling.

  • Stay Focused

Section thickness totalizer and counter with reset button facilitate target preparation and promote fast trimming between levels. With the reverse section counter, a preselected number of sections can be carried out in both sectioning and trimming mode.

  • Comfortable Sitting Position

The Leica CM3050 S cryostat with its low working height and available knee space allows the user to work comfortably while sitting.
