Dry Polystyrene Microspheres
Diameters of 200 to 1000 μm are made from dry polystyrene microspheres cross linked with divinylbenzene (PSDVB). 240 μm Mean diameter has been calibrated with NIST™ traceability using Thermo Fisher Scientific™ microscopy methods. The Dry particles are quite accurate in size diameter and lot-numbered for convenient technical service and support after the sale. Each Bottle includes a Certificate of Calibration and Traceability to NIST, which includes a description of the calibration method and its uncertainty; Table of chemical and physical properties and (MSDS) Material Safety Data Sheet. Typically sold in 1 gram volume per bottle, but can be special ordered at higher volume per bottle.
