1.6 Brief Description of Use, Function, and Sequence
Use
The CUT 4060E rotary microtomes are manually operated instruments for use in all
work involving paraffin wax and solid cut microtomology within the disciplines of
biology and medicine, and within industry at large.
Function and Sequence
Manually rotating the handwheel on the rotary microtome translates into vertical
movement of the fixture holding the specimen. To produce the cut, resharpenable
knives or throw-away blades are used, which are adapted and attached to the various
knife holders.
A microtomic cut is made during the downward motion of the specimen (cutting action).
By continuing to rotate the handwheel further in a clockwise direction the specimen
starts to rise again in its return motion.
Owing to the different types of operation, cuts may be carried out manually by means
of the handwheel, semi-automatically by means of the hand control panel, and by
means of the foot switch, that will have to be separately ordered.
The selected feed for the thickness of cut is instigated at top dead center.
Rapid advance of the specimen towards the knife is achieved by means of the coarse
feed mechanism.
A universal clamping fixture for holding a variety of specimens is provided.
As a result, simple alignment to the plane of cut is possible using the facility for
orientating the specimen.
The various knife holders enable trouble-free use of a variety of knife types and
thereby provide facility for making adjustment to suit the application in question.
