For calibration of magnifications in electron microscope studies. Used in particle counting devices, e.g. the Coulter Counter. For determination of unknown specimen
concentrations. If the concentration of latex particles, of uniform size, in a known volume is added to a sample of suspended matter of the same volume, a close approximation of the unknown concentration may
then be determined. When used for magnification determinations, care must be taken to protect the latex particles from the heat of the electron beam which deforms them. This is done by evaporating a light
carbon coating on the specimen prior to electron microscopy. Store at room temperature. Do not open vial until ready to use. When diluting the latex suspension use distilled, deionized water. Sold 10 ml of
each latex solution in a special plastic dispenser. 0.2% (w/v) solids. |
