Sample preparation equipment refers to equipment used for the preparation of physical specimens for subsequent microscopy or related disciplines - including failure analysis and quality control. The equipment includes the following types of machinery: Precision cross-sectioning saws; Precision lapping & polishing machines; Selected Area ...
Struers provide cutting, mounting, grinding, polishing, microevaluation, hardness testing equipment [6] and consumables [4] for the analysis of metal samples. Government departments, [ 7 ] universities, [ 8 ] NASA [ 9 ] and the International Metallographic Society use Struers equipment in the analysis metal or material samples.
Mechanical preparation is the most common preparation method. Successively finer abrasive particles are used to remove material from the sample surface until the desired surface quality is achieved. Many different machines are available for doing this grinding and polishing , which are able to meet different demands for quality, capacity, and ...
The preparation of ceramic specimens for microstructural analysis consists of five broad steps: sawing, embedding, grinding, polishing and etching.The tools and consumables for ceramographic preparation are available worldwide from metallography equipment vendors and laboratory supply companies.
The selection of microtome knife blade profile depends upon the material and preparation of the samples, as well as the final sample requirements (e.g. cut thickness and quality). Design and cut types

The box was beautifully organized, with the Culture Guide and a thank you/welcome note from founder Danny Taing on top, and an artfully arranged selection of savory and sweet snacks underneath.
Sample preparation may involve dissolution, extraction, reaction with some chemical species, pulverizing, treatment with a chelating agent (e.g. EDTA), masking, filtering, dilution, sub-sampling or many other techniques. Treatment is done to prepare the sample into a form ready for analysis by specified analytical equipment.
