2.2.6 General parameters

2.3 Instrument parts

2. Characteristics of the Leica CM3600

Protective class: I
Pollution degree: 2
Overvoltage installation category: II

The Leica CM3600 consists of a sliding microtome in a large-volume
cryochamber. The instrument is designed for cryosectioning large speci­mens 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 section­ing 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).

Leica CM3600 – Cryomacrotome

17

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 speci­men 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 pro­grammed 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 sec­tions 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.

Never leave the instrument unattended when
the knee lever is folded out (1) to prevent the
microtome from being set in motion acciden­tally.

Always swing the knee lever
upwards before leaving the instru­ment.

The window is heatable and equipped with a
lock button (2). To open the window, lift lock
button (2) slightly upwards and turn it by 180°.

3. 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).

24

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.

Instruction manual V 6.0 - 08/2006

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), sec­tion 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.

Leica CM3600 – Cryomacrotome

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 appropri­ate lifting gear. Do not attempt to lift the microtome from the
chamber manually, even if several persons are there to help.

4. 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 perfor­mance 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 suffi­cient).
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.

should be available.

If no ceiling crane is installed yet, we recommend the special
Leica crane „KR-CM3600“.

Telephone connection

For remote failure diagnosis, a telephone connection must be available to
hook up the modem. The phone connection must be direct, i.e. must not
be controlled by an additional computer (server).

Compressed air supply

If you want to use the optional extraction system:
Compressed air supply for the extraction system (p = 5 - 8 bar) must be
available.

7.5 Specimen stages

This chapter provides instructions on how to insert the knives.

There are three different types of specimen stages:

• Special holder, orientable, with ball-and-socket joint,

• Specimen stage, orientable, with ball-and-socket joint,

90

• Specimen stage, non-orientable.

Instruction manual V 6.0 - 08/2006

7. Operating the Leica CM3600

When inserting the specimen stages, bear in mind the following:

• Prior to sectioning, the specimen stage should have been stored

inside the cryochamber for at least 24 hours, to make sure it has the
correct sectioning temperature (ca. -20° C).

• To mount the entire block (specimen block on specimen stage) onto

the sledge, first bring the knife holder to its upper limit position. For
further information, refer to chapter 6.4.5.

• The total height of the specimen stage plus specimen block must not

exceed 70 mm.

Since there is a considerable risk of injury when inserting the specimen
stage/block, please observe the following safety measures:

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.

Leica CM3600 – Cryomacrotome

Prior to any work involving the knife, microtome or inside the
cryochamber, swing the knee lever upwards. For further
