1. INTENDED USE
The vacuum tissue processor MTM II is intended for automated fixation, dehydration
and paraffin infiltration of histological samples for professional use in routine and
research laboratories in the fields of biology, medicine and industry.
MTM II is equipped with an enhanced heat exchanger (EHE) that allows conventional
overnight tissue processing, semi-rapid processing of larger samples and fast processing
of biopsies.
The MTM II tissue processor recycles the air utilized to move the reagents to and from
the processing chamber. An effective charcoal filter on the external air-outlet reduces
the exhaust fumes to acceptable and safe levels. The wax and reagent bottles can be
rapidly removed and easily reinstalled in their housing slots. The control devices
(hardware and software) are based on the most up-to-date processing control
technologies. Up to 18 different programs can be permanently stored and be easily
modified. The 18th program is a special “REVERSED” program that is used to de-process
samples that have not had good infiltration.
During a run, every step and action is displayed on the screen, such as current step and
function (emptying, filling, etc.), processing chamber and wax heating chamber
temperatures, processing chamber pressure, completion time and date, and any other
parameter necessary to simplify the use of the instrument. In the event of power
failures, the computer saves all the data necessary to restart the process exactly where it
was interrupted. If the interruption happens during the wax stages, particular
precautions are taken to guarantee melting before any wax filling or emptying begins.

3. SAFETY NOTES
The institution which owns the unit and the persons working with the unit, servicing or
repairing it have the responsibility for a hazard-free use.
•
Severe damage can result if the instrument is connected to a
power supply different from the rating stated in the identification
tag placed on the rear of the instrument.
•The instrument must NEVER be used without being connected to
an appropriate and fully efficient ground connection.
•If damages due to transport occur, DO NOT use and DO NOT
connect the instrument to a power source. Contact our technical
service.
•This instrument has been designed to work 24/7; for this reason
and for operative precautions, the power switch is placed on the
rear of the instrument.
•Access to the instrument’s internal components is reserved only to
specialists trained in the service of the instrument.
•Always disconnect the processor from the electrical main source
before accessing the electronics and internal parts.
•BEFORE replacing fuses, disconnect the instrument from the power
source.
6 Manual_MTM_II_2021-10-010.00_EN.docx
•
Always make certain to correctly engage the reagent bottles.
•DO NOT open the processing chamber lid when the instrument is
working without following the instructions contained in this
manual.
•Use specific precautions in handling flammable reagents such as
ethanol (wear protective gloves and eyeglasses).
•Use specific precautions in handling liquid waxes as they can cause
burns.
•The emptying and filling of reagent bottles must only be done only
by qualified technicians.
•Due to the presence of flammable substances inside reagents
bottles, it is recommended to:
oAvoid smoking near the instrument
oAvoid using open flames near the instrument (e.g. Bunsen
burner)
oDO NOT wear clothes that can create electrostatic charges
while handling reagents (wool, synthetic fibers, etc.)
•Contaminated reagent waste must be disposed off in accordance
with all applicable local laws, ordinances and safety standards.
•Use only original spare parts supplied by the manufacturer or by
authorized dealers.
•DO NOT extract bottles, replace reagents or do other maintenance
operations when the instrument is operating.
•To complete the knowledge on the instrument safety please read
also the chapter SAFETY DEVICES near the end pages of this
manual.

3.1ELECTRICAL POWER CONNECTION
Do not use any extension lead.
Make sure that electric power is constant:
•
This should be examined during installation of the unit by a
competent person.
•Use a dedicated fuse for the unit.
•Do not connect another unit to the same power circuit.
•Before turning on the instrument, check if the voltage of the mains
supply is identical with the name plate of the unit.
