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.
