Now Available!! In addition to the standard latex spheres listed below, we now offer NIST traceable polystyrene latex spheres in various sizes. Certificate of Compliance available. Please call us for details.
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.
Note: Particle sizes may vary somewhat from those listed. Exact size listed on each vial.
