Influence of microtomy on measurements of orientation

Polymer Testing, 1994
Abstract The correct measurement of orientation and crystallinity on thin sections microtomed from larger specimens requires a knowledge of the influence of sectioning on these properties. In this work, the measuring technique used is FTIR, using dichroism to determine the orientation and regular FTIR to determine the degree of crystallinity.

Mastering the art of sectioning: a comprehensive guide to slide-microtome technology and histological applications

Frontiers in Veterinary Science
The well-known technique of microtomy, which is an essential cutting tool, was first developed for light and transmission electron microscope uses, but it is currently also utilized to prepare specimens for atomic force microscopy (AFM), ion microscopy ...

Limits of Vibrating Microtomy

Journal of Histochemistry & Cytochemistry
The Vibratome, or vibrating microtome allows sectioning of the mouse brain with a reliably established thickness from 50 µm, but they have a strong limitation on the size of the sample suitable for cutting. Herein is described the construction with publicly available element base (from parts for a 3D printer) a so-called 3D-vibrating microtome capable ...

CODEX Microtomy Tracking Sheet v1 [PDF]

, 2019
Microtomy Tracking Sheet for CODEX Specimens The process of sectioning CODEX specimens presents tediously at the tissue block trimming and microtomy stage. As you begin to cut into a new or already used tissue block, you must keep track of how many microns of tissue are removed from the section during trimming, and also during microtomy. Attached is a

Low Speed Microtomy for the Electron Microscope

Experimental Biology and Medicine, 1949
The beam of a 50-kv electron microscope does not penetrate specimens that are thicker than 0.1 μ. Thus, in order to study biological specimens with this type of microscope we have further developed the technic described by Pease and Baker,1 who altered a Spencer Rotary Microtome (model 820) by adding a wedge to the mechanism for forward movement.

Modified embedding procedure for microtomy of large particle zeolites

Journal of Electron Microscopy Technique, 1990
AbstractA method is described to strengthen the binding of organic resin to inorganic zeolite, allowing large particles to be microtomed. For FeZSM‐5 aggregates the particle size limit increased from 3 μm to greater than 20 μm in diameter by application of this method.
