Mechanical Disruption Methods: Grinding

CryoGrinder™ for Small Sample Grinding: As small samples are difficult to recover from standard mortar and pestles, the CryoGrinder™ serves as an alternative tool for cryogenic grinding. Small samples, which are pulverized cryogenically using a mortar and pestle, are spread as a fine powder over the mortar surface. This is difficult to collect. The CryoGrinder™, which is essentially a miniature mortar and pestle, possesses a small well and associated pestle designed for samples

Processing Small Tissue or Cell Samples using Sample ...

Sample Grinding Kit is designed to disrupt cell or tissue samples. It utilizes an abrasive grinding resin and grinding pestle to rupture cells for protein extraction. Intracellular organelles are also disrupted, resulting in the liberation and extraction of all proteins soluble in the extraction solution. Samples of 100 mG or less can be processed in as little as 10 min.

Safe and Efficient Cryogenic Grinding of Food Samples ...

01/03/2018  Most sample materials can be ground to the required analytical fineness at room temperature. However, there are limits, for example when even a small temperature increase affects the sample in a negative way; or when the material is very elastic and will only be deformed. Moreover, food samples which are fatty or sticky may block the mill. Therefore, cryogenic grinding is the best way to pulverise food samples

Metallographic grinding and polishing insight Struers

Plane grinding with diamond is the best choice to ensure flat samples from the very beginning of the preparation. Fine grinding with either MD-Largo or MD-Allegro will provide the best possible planeness. To avoid relief, preparation time and the type of polishing cloth used are the most important parameters.

Guide to the Disruption of Biological Samples - 2012

On the small size, garnet, cut wire, silica gel, and similar sharp grinding media can effectively slice resilient samples, particularly when used in conjunction with a larger grinding ball. Satellites (shaped like Saturn) and cylinders can also be effective breaking up tough samples due to the sharpness of their edges. We routinely use a combination of garnet (a hard, sand-like mineral) and ...

Small samples are generally mounted in plastic for convenience in handling and to protect the edges of the specimen being prepared. Compression-type molding is commonly applied to encase specimens in 1 to 1.5 inch diameter plugs of a hard polymer. Compression molding materials are classified as either thermosetting or thermoplastic: 1) Bakelite is a low cost, relatively hard thermosetting ...
