Leica® CM1860 Cryostat

The Leica CM1860 is the ideal cryostat for creating high-quality sections. A 1 year parts and labor warranty is included.


Leica® CM1860 Cryostat

The Leica® CM1860 is your perfect assistant for high-quality, fast and safe sectioning. This high-throughput cryostat delivers diagnostic confidence by reliably producing quality sections to help provide an accurate diagnosis – even with the most complicated tissue types. Personnel near the cryostat are protected by the antimicrobial nano-silver coating, AgProtect, which provides outstanding safety by reducing exposure to surface pathogens. AgProtect covers the cryostat’s external upper surfaces and constantly protects individuals in the work area by penetrating the membranes of microbes to prevent replication. The unique premium blade holder safety features combined with the ergonomics of a designated finger guard, blade ejector and palm rest for brush technique users improve safety and comfort while sectioning.
