9 Leica CM1950 – Cryostat
2.3 General safety notes
The CM1950 is a cryostat with an encapsulated microtome and separate specimen cooling.
It is primarily used for work in the area of fast-cut diagnostics.
The displays and instrument controls are easy to operate due to their largely self-explanatory
symbols. LED displays make it easy to read. The cryochamber is made of seamlessly welded,
high-quality stainless steel that is free of difficult-to-access corners and thus easy to clean and
disinfect.
2.4 Unpacking and installation
To ensure proper function of the instrument, it must be set up with a minimum distance on all
sides from walls and furniture ( see Chap. 6, 6.1 "Site requirements" ).
• The instrument may only be transported in an upright or slightly inclined position.
• To ensure a safe transport with a fork lift 3 people are required: one operating the fork lift,
and the other 2 holding the instrument on either side to prevent it from sliding down.
• Before connecting to the power supply system, please observe "Technical Data" !
• Never connect the instrument to a power socket that does not have a protective conductor
terminal.
Length of the power cable: up to 3.5 m extension possible: No
2. Safety and Design
After transporting, wait at least 4 hours before turning the instrument on. This waiting period
is necessary to allow the compressor oil, which may have been displaced during transport, to
return into its original position. Any condensation on electrical parts that has formed due to
temperature differences during transport must be allowed to dry completely. Failure to comply
with this can cause severe damage to the instrument!
Flammable substances may not be used in the Leica CM1950 when it is turned on and plugged
in. Do not place staining solutions or other liquids on top of the instrument.
The instrument has been designed and constructed with the latest state-of-the-art technology
and according to recognized standards and regulations with regard to safety technology. Oper-
ating or handling the instrument incorrectly can place the user or other personnel at risk of in-
jury or can cause damage to the instrument or other property. The instrument may be used only
as intended and only if all of its safety features are in proper working condition. Malfunctions
that impede safety must be remedied immediately.
