An Inexpensive Vibrating Microtome for Sectioning Fixed Tissue

Biotechnic & Histochemistry, 1980
A tissue sectioner which uses a vibrating razor blade and a simple mechanism for the elevation of the tissue can be constructed for less than fifty dollars. The razor blade in fixed to the vibrator of a hair clipper and a nut and bolt serve as the tissue advance mechanism. A metal disc attached to the nut is used for the stage.

Simple microtome for sectioning cellular foam

Journal of Applied Polymer Science, 1967
AbstractA simple, inexpensive microtome was developed for sectioning polystyrene foam prepuff. The cell structure is well defined and wall thicknesses can be measured easily from photomicrographs prepared with the microtome.

Improved Paraffin Sectioning with Etched Microtome Knife Edges

Biotechnic & Histochemistry, 1969
Carbon steel microtome knives etched with 0.1 N HNO3 for 2 min display a very sharp cutting edge. Over a period of 3 yr no damage to the steel has been detected. The effect on paraffin sectioning was observed by comparing acid-treated knives with nonetched but well-sharpened ones. Sections of whole eyes cut with an etched blade showed approximately 15%

Cutting Frozen Sections on a Paraffin Microtome

Stain Technology, 1956
Into a hole drilled in a block of dry ice, a metal microtome object disk is placed to cool. A drop of water is placed on the disk, and the specimen to be cut is fixed in place. By setting the dry ice in a well-insulated box, the specimen is thoroughly frozen.

A technique for microtome sectioning of charcoal

Journal of Microscopy, 1973
SUMMARYSectioning of charcoal is extremely difficult since the knife usually shatters the section into minute fragments. In order to prevent such shattering it is necessary to both infiltrate the charcoal with a hard wax and to support the section during cutting with adhesive cellulose tape.

Plastic Deformation in Microtomed Sections

Proceedings, annual meeting, Electron Microscopy Society of America, 1971
The output of the ultramicrotomy process with its high strain levels is dependent upon the input, ie., the nature of the material being machined. Apart from the geometrical constraints offered by the rake and clearance faces of the tool, each material is free to deform in whatever manner necessary to satisfy its material structure and interatomic ...

A new microtome for thin-sectioning for electron microscopy

Biochimica et Biophysica Acta, 1953
Abstract A new microtome is described for the cutting of thin sections for the electron microscope. The specimen is mounted on an arm attached to a constantly rotating shaft. The advance mechanism for the knife consists of a stiff member supporting the knife which is bent by stretching a relatively flexible spring attached to it.
