Ready-to-use standards for validating optical particle counters with no dilution and handling. The products are suspensions of monodisperse polymer microspheres in water with a concentration of 2000 particles per mL. A magnetic stir bar is included in each bottle for clean
convenient and direct sampling by instruments. Designed for regular use in liquid particle counters to verify instrument calibration before each use. Their certified diameters are traceable to NIST. They are packaged as 100mL screw-cap bottles
sufficient for four or five calibration procedures on most counters. Typical applications as pharmaceutical
food processing
beverage
and wastewater.Ezy-Cal Count Precision Standards
