THE Disinfecting Clinical Cryostats

Leica CM1950 Platform 

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

NEW: CryoZone blade holder and anti-roll guide cooling

Consistent, motor-driven cutting stroke (optional) 

Vacuum-assisted sectioning aid (optional) 

High precision microtome with exact stepper motor object feed. 

THE cryostats 

for high quality sectioning 

Obtain high quality sections through: 

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. 

5

Histology laboratorires continue to express major concerns 

about biohazard exposure and non-ergonomic work practices. 

As a result of their feedback, the Leica CM1950 family of 

cryostats is designed to provide maximum protection from these 

risks at all stages of the sectioning process. 

6 

Certified UVC disinfection of exposed surfaces and air 

within the cryochamber at cold temperatures 

AgProtect antimicrobial nanosilver coating on the 

outside surfaces of the cryostat 

Optional Section Waste Removal System with a series of 

three filters 

Ergonomic exterior cabinet design with rounded edges 

and comfortable working height 

Optional ergonomic chair and foot rest 

THE cryostats 

for the highest user safety 

Leica’s built-in UVC disinfection system provides 

certified protection from infectious material and 

minimizes the risk of contamination in the cryochamber. 

Scientific studies prove that surface 

disinfection from bacteria, viruses, and fungi can 

be achieved with UVC light. Certification proving the effectiveness 

of UVC disinfection against a range of microorganisms can be 

downloaded from www.leica-microsystems.com/cm1950_safety, 

which includes detailed information on the test procedure and the 

efficacy of UVC disinfection. 

To efficiently reduce the propagation of infectious agents on 

the outside surfaces of the cryostat, the Leica CM1950 family 

features an antimicrobial nanosilver surface coating, called 

AgProtect. Silver (Ag) ions are well documented 

for their ability to reduce bacterial growth. 

Protect 

Section waste is easily removed by using Leica’s optional 

Section Waste Removal System during trimming with the 

magnetized nozzle, or during extensive cleaning with the 

flexible hose. Solid waste is collected in a concealed primary 

filter system and air is filtered through a HEPA filter for 

added safety in the laboratory environment. Liquid condensate 

is collected in a condensate bottle for safer disposal.

The ergonomic design of the Leica CM1950 protects the user 

from sharp edges and helps prevent work-related musculoskeletal 

disorders (MSD) and repetitive strain injury (RSI). 

Rounded edges allow the user to adopt a comfortable working 

position. Bright, glare-free illumination helps reduce eye 

fatigue. 

The new disposable blade holder CE with integrated, colored 

safety guard and blade removal aid makes blade handling 

safer. For users who prefer using the brush technique during 

sectioning, the palm rest can be used instead of the anti-roll 

guide. 

For individual user comfort, the Leica chair and height 

adjustable foot rest are available as optional accessories.

Simple specimen identification using the optional, color-coded specimen discs 

Fast, efficient specimen orientation with clearly defined zero position 

Disposable blade holder for both high and low profile blades 

Frost-free, enclosed microtome assembly 

Optional motor drive for specimen sectioning 

THE cryostats 

for highly efficient workflow 

The best workflow for efficient operation is achieved by: 

Certified UVC disinfection at low temperatures – does not produce condensation or 

contaminated waste, is effective at low temperatures, and can be terminated at any 

time to process urgent cases 

Easy for the multi users: the selfexplanatory, 

single-function keys and 

easily readable LEDs help prevent 

operating errors, facilitate cryosectioning, 

and make scrolling through 

multiple menus unnecessary. The 

control panels are comfortably positioned 

in the armrests to eliminate 

the need to reach into the cold chamber 

to use or adjust settings. 

Tools, glass slides, staining containers, 

etc. can be stored in a recessed 

area on top of the cryostat to keep 

them immediately at hand.

Sectioning tools/aids etc. can be conveniently placed on 

the optional, movable shelf. 

The specimen discs can be pre-cooled in the optional 

internal storage container, and then easily organized and 

transported. 

Optional color coded specimen discs help identify specimens 

coming from multiple sources. The specimen disc 

features a visual specimen orientation aid to enable precise 

orientation. 

A clearly defined zero-position allows faster 

specimen alignment prior to sectioning and 

easy realignment if the specimen is removed 

from the object head. 

With the new disposable blade holder CE blade 

exchange is simple and fast. The holder’s lateral 

displacement function allows the use of the full 

length of the blade. Small and large sections are 

easily lifted from the large, horizontal pressure 

plate.
