Recently in the histopathological examination, as for specimens of
particularly large area or hard materials as well as for special
purposes, very thin specimens such as of 1-3 microns or other sections
of various kinds have been increasingly demanded. Large Sledge Microtome
has been fabricated by improving hitherto used Microtomes providing
their inherent characteristics to meet the above requirements. as such
this model is highly recommended for all biological and reasearch
laboratories for sectioning of soft tissues and also hard materials such
as stem, root or other Botanical objects etc. It is very suitable also
for Ear, Nose and Throat Departments where sections of fairly large
specimens are required. If incorporated a Freezing attachment, this
microtome can be as a Freezing Microtome.
Introduction
This
Microtome consists of Main body (Slide-Way), Object Clamping Stage,
Feeding Device and Knife Clamping Block. The body of the Microtome has 3
tracks of 400mm horizontal slide for knife clamping block and 3 tracks
of inclined slide for object clamping stage and feeding device. The
shape of the knife block and its contact with 9 tracks eliminate riding
up or tilting of the Microtome knife during the cutting.
The
knife Clamping Block has a ball for clamping the knife holder and a
handle. The knife Holder is fitted with two screws serving to eliminate
vibration of the knife. The clearence angle of the knife can be adjusted
by means of a screw drive.
The object Clamping Stage has a
sliding stage and object clamping holder, THe object clamping holder is
equipped with two rack and pinion swivelling device which can be
oriented for adjustment of cutting object. It can be raised or lowered
by rack and pinion for the approximate height adjustment of the object.
The specimen blocks upto 30x30mm can be held in it.
The Feed
Device can be adjusted for section thickness between 1 to 10microns by
increment of 0.5micron by hand, with settling drum calibration scale.
The specimen rises accurately by a micrometer screw fitted with a
ratchet gear and lever transmission. The feeding screw is 40mm. in
effective length and of open-and-close half-nut type, it returns to the
initial position when the handle is opened.
Thin and accurate paraffin sections can be readily obtained. This may also be applied for preparing celloidin specimens..
