Leica CM1950 Platform
Protect
THE cryostats for high quality sectioning, user safety and efficient workflow
The Leica CM1950 platform is the latest innovation in a long line of distinguished
cryostats manufactured by Leica Microsystems. Leica designed and developed the
new family of cryostats based upon users’ feedback and their requirements for
high quality sections, user safety, and efficient laboratory workflow.

ple specim
Learn quickly and work confidently using the externally located, self-explanatory controls
with easily recognizable symbols.
For an extra measure of safety, the inside of
the instrument features an ozone-free UVC
disinfection system that is certified to be
effective against most bacteria, virus, and fungi, even at cold temperatures.
Increased safety for the user and others in the
immediate work area: Leica’s AgProtect™
antimicrobial nanosilver surface coating
deters the propagation of infectious agents on
the outside of the instrument.
To protect the laboratory environment from
contamination, a multi-filter system (including
HEPA filter) removes particulates and cleans
the air exhausted from the optional Section
Waste Removal System
Liquid condensate
collected in an eas
ble waste container

Store tools, glass slides, staining containers, etc. in a
recessed area on top of the
cryostat to have these items
immediately at hand.
For extra ease of use and consistent sectioning of all specimen types, an optional sectioning motor drive is available.

THE cryostats
for high quality sectioning
Obtain high quality sections through:
NEW: CryoZone™ blade holder and anti-roll guide cooling
•
Maintaining the ideal object temperature for specific specimens
•
Great stability of the microtome and blade holder system
•
Extreme accuracy of the stepper motor object feed
•
Consistent, motor-driven cutting stroke (optional)
•
Vacuum-assisted sectioning aid (optional)
•
High precision microtome with exact stepper motor object feed.
•
CryoZone™ – the cool way to improve section quality
The CryoZone™ system controls a zone of uniformly cool air in the critical areas of the cryochamber. This
cool air circulates around the specimen, knife and anti-roll guide to create the optimal conditions for consistent, high-quality sectioning.

Efficient specimen loading is achieved via single lever
operation that provides maximum clamping force independent of individual user strength.Direct contact cooling
through the (optional) actively cooled object head facilitates rapid changes of specimen temperatures to provide
the best conditions for sectioning various specimen types.
High specimen stability is achieved by adherence to deeply
grooved specimen discs. Specimens freeze quickly
because the pre-cooled discs feature a large back surface
that fully contacts the freezing shelf with integrated Peltier
element.
Superior sectioning of routine, hard, and/or large samples is
achieved using a choice of knife/blade holders as well as the
new dove tail mounting system that provides increased stability and extended working distance. The new CE holder for
high and low profile disposable blades evenly distributes
clamping pressure across the entire length of the blade,
which provides vibration-free sectioning.
The new CN and CNZ knife holders are available for steel
or tungsten carbide knives (optional accessories).
The optional vacuum sectioning aid achieves time-saving section preparation and reduces section curling.
