2.3 Instrument parts
The Leica CM3600 consists of a sliding microtome in a large-volume
cryochamber. The instrument is designed for cryosectioning large speci-
mens or for processing specimens with the so-called cryo-planing
technique.
The large-scale heavy-duty microtome is made for sectioning large
biomedical and industrial specimens such as whole animals or large
tissue specimens by applying the sectioning techniques for large-surface
sections. The sturdy construction of the instrument also permits section-
ing very hard specimens such as undecalcified bones.
The microtome is housed in a convection-cooled large-volume
cryochamber.
The large chamber in connection with the special cooling system enables
dehydration of sections within a very short time.
The low temperatures are achieved and maintained by cold air circulating
inside the cryochamber. A fan controls the air circulation speed.
The large specimens are frozen onto metal specimen stages which are
subsequently clamped in the specimen sledge.
Optionally the instrument can be operated with an extraction system
which largely prevents the cryochamber being soiled with section waste.
2.4 Function
The motor-driven specimen sledge moves horizontally underneath the
knife, either producing a section (cryosectioning) with each stroke or a
high-quality specimen surface (cryo-planing technique).

2.
Characteristics of the Leica CM3600
Prior to each sectioning stroke, a stepper motor feeds the microtome
knife downwards towards the specimen by a selected amount of microns
(section thickness).
During each return stroke of the specimen sledge, the stepper motor
automatically carries out a knife retraction movement, programmable
between 50 and 250 μm. This protects both the knife edge and the speci-
men surface from being damaged.
Before starting the next sectioning stroke, the motor lowers the knife
towards the specimen surface by the selected sectioning feed plus the
set value for knife retraction.
Trimming is programmable; the desired section thickness can be
preselected.
The number of sections to be preformed during trimming can be pro-
grammed via the section counter. When the programmed number of
sections has been carried out, the microtome will stop automatically.
Once the desired specimen block height has been reached, those sec-
tions that will actually be used for further examination are collected
manually via the knee lever.
The Leica CM3600 is operated via PC and/or manually via the knee lever.
All data entries are made via the PC.
The Leica CM3600 features two automatic defrost cycles.
Defrost cycle duration is software-controlled. If the evaporator surface is
already completely deiced before the programmed defrost time is up, the
defrost cycle will be aborted. In addition, manual defrost cycles can be
set as needed.

Safety
As you work through the instruction manual, familiarizing
yourself with the instrument, do not yet install a knife or
specimen.
Below you find a summary of all warnings contained in this instruction
manual.
Any use of the instrument not described in this instruction
manual is considered improper.
Always swing the knee lever upwards before leaving the
instrument.
When opening the chamber lid, the lid retainer must engage.
Prior to exchanging the fuse in the socket panel, switch the
instrument mains switch off and unplug the instrument from
mains. Only use fuses of the same type and characteristics as
originally supplied (see chapter 2.2 ‘Technical data’ for fuse
specification).
The control PC as well as all peripherals connected to it
(printer, monitor, etc.) are set to an input voltage of 230V/50Hz.
For reasons of compatibility (CE Directives, UL Approval) they
may only be connected to the socket panel of the instrument,
using the connecting cables supplied.
Prior to any work involving the knife, microtome or inside the
cryochamber, activate the emergency stop switch. For further
information, refer to chapter 3.4.1.

3. Safety
Prior to any work involving the knife, microtome or inside the
cryochamber, swing the knee lever upwards.
For any work involving the knife, microtome or inside the
cryochamber always wear special protective gloves.
For reasons of safety and accuracy, the maximum trimming
thickness should not exceed 100 μm per section.
When trimming biological material (particularly bone), sec-
tion thickness should not exceed 50 μm.
Never try to catch or grab a knife.
Never introduce your hands into the space between specimen
and knife.
Radioactive specimen waste must be disposed of according to
the local radiation safety regulations.
For removing the microtome (approx. 190 kgs) from the
cryochamber, a ceiling crane capable of carrying that weight
should be available.
For safety reasons, we strongly advise you against lifting the
microtome (190 kgs) from the cryochamber without appropri-
ate lifting gear. Do not attempt to lift the microtome from the
chamber manually, even if several persons are there to help.

Site requirements
4.1 Site requirements at place of installation
If possible at all, the room should be air-conditioned.
Relative humidity≤ 60 %.
Room temperature should not exceed 22 °C.
If ambient conditions are not maintained as specified, instrument perfor-
mance may be negatively affected (lowest specified temperature may not
be reached, frost may accumulate).
All transportations paths for the Leica CM3600 must at least be 1.5 meters
wide, especially doorways must have that width. 1.5 m is wide enough for
the instrument to pass through the doorway at an angle (if the instrument
can pass straight through the doorway, a width of 95 cm will be suffi-
cient).
The Leica CM3600 has a total length (refrigeration and control unit plus
cryochamber) of 2.7 meters or 2.8 meters including the connecting cables
on the left side of the refrigeration and control unit, i.e. a minimum wall
length of 2.9 meters is required to install the instrument. Ideally the wall
should measure 3.5 meters or more to provide easy access to the left side
of the unit for technical service work. The required minimum distance
between the back panel of the instrument and the wall is 30 cm, the
recommended distance is 50 cm.

Proceed as follows:
1. On the computer screen, open the „Main window“, select „MANUAL“
mode of operation. Subsequently, select the desired section thickness
and the cutting window. For further information, refer to chapter 6.4.
7.8.1 Sectioning the specimen
For the sectioning procedure, you need brush, sectioning tool and spe-
cial section collecting tape and - depending on the application - a dehy-
dration frame.
The required accessories should be stored in the cryochamber
for some time prior to sectioning to make sure they have the
same temperature as the specimen.
Proceed as follows:
1. Activate the knee lever - for further steps, please see chapter 3.4.2.
7.8.2 Collecting the sections
Prior to removing a section, an appropriately sized piece of tape must be
attached to the specimen block surface. When doing so, please comply
with the following safety instructions:
Wear protective gloves.
Never try to catch or grab the knife.
Never introduce your hands into the space between specimen
and knife.

7. Operating the Leica CM3600
Proceed as follows:
1. Select manual mode of operation and the desired section thickness.
2. Activate the section documentation function.
3. Use the knee lever to move the sledge to the right-side reversal point
(left edge of the specimen block just about clears the knife).
4. Cut the section and clean the specimen surface with the brush.
5
Cut off a desired length from the tape roll. The width of the tape should
not be larger than the specimen block; the length should be long
enough to easily hold the tape with your left hand while sectioning and
to attach the completed section to a dehydration frame.
6. In case the tape has been kept outside the cryochamber, let the tape
length rest a few seconds inside the cryochamber before attaching it
to the specimen block - this will ensure that tape and specimen block
have the same temperature.
7. Use the sectioning tool to aid in pressing the tape onto the block
surface.
8. Fix the tape first in the middle and then press out to both ends. This
method prevents air bubbles from being trapped between tape and
block surface.
9. Rub with a precooled brush, paper towel or cotton wool to assure
good contact of the tape with the specimen surface. Never touch the
specimen block face with your hands.
10. Hold the left end of the tape in your left hand. Drive the microtome
gently until some of the embedding medium is apparent on the left
edge of the tape.
11. Use the sectioning tool to aid in pressing the tape onto the block
surface. To do this, press the sectioning tool firmly on the block close
to the knife edge.
12. Shift the knee lever to start sectioning - keep the sectioning tool
pressed on the specimen block.
Carefully guide the tape to the upper left (away from the specimen) -
do not pull tightly!
13. Completely remove the section and stop the sledge behind the knife.
Be sure to leave the section in the cryochamber.
It must not be exposed to room temperature.
14. Check the section.
15. Add the section data to the documentation.

7.
Operating the Leica CM3600
16. Attach the section to a dehydration frame which has already been
kept in the cryochamber for a while.
17. To speed up the dehydration process once you are done with the
sectioning work, the automatic or manual dehydration function of the
instrument can be activated.
7.9 Dehydrating the sections
To be able to store the sections or use them otherwise outside the
cryochamber, they must be properly dehydrated. For this purpose, the
instrument has a automatic as well as a manual dehydration function.
During dehydration, the fan speed is increased, thus speeding up the
removal of moisture-saturated cold air. The moisture is separated at the
evaporator.
During the course of a dehydration cycle, the automatic defrost cycles
are skipped and carried out immediately after the dehydration procedure
is completed.
Proceed as follows:
1. Open the „Main window“ on the computer screen and select auto-
matic dehydration. For further information, refer to chapter 6.4.

Cleaning and maintenance
8.1 Cleaning
For cleaning and disinfection of the stainless steel cryochamber and the
microtome, use commercial alcoholic disinfectants or alcohol.
The outer surfaces of the cryochamber and the control unit can be
cleaned with mild household cleaners or with alcohol-based disinfectants
or pure alcohol.
Do not use any other cleaning products. The enamel is neither
resistant to acetone nor to xylene.
Radioactive specimen waste must be disposed of according to
the local radiation safety regulations.
8.1.2 Removing the microtome from the cryochamber
Normally it is not necessary to extract the microtome from the cryocham-
ber. However, if you wish to do so, i.e. for thorough cleaning, it is strongly
recommended to use an overhead crane which has to be installed on the
ceiling above the instrument.
For safety reasons we strongly advise you against lifting the
microtome (190 kgs) from the cryochamber without appropri-
ate lifting gear!
Also, do not attempt to lift the microtome from the chamber
manually, even if several persons are there to help.
For removing the microtome (approx. 190 kgs) from the
cryochamber, a ceiling crane capable of carrying that weight
should be available.
Tools required:
•
Allen key (size 6).
Proceed as follows:
1. Comply with the safety instructions provided in chapter 8.1.2.
