The Endecotts Calibration Samples are microspheres formed of soda-lime glass that range from 3.35mm down to 20 micron sizes. Because of the precise nature and extent of the range of spheres, samples can be supplied to enable the accurate calibration of individual sieves. The Endecotts Calibration Samples will enable you to calibrate your test sieves to an accuracy of approximately 1 um. [Single Shot Vials.]
