4000 Series Dry Monosized Beads
- Particle spheres are used instead of irregularly shaped particles.
- Mean diameters have been calibrated with Applied Physic's NIST™ traceable microscopy methods.
- Size distribution and uniformity are measured by electrical resistance analysis or optical microscopy.
- 4000 Series particles from 200 to 1000μm are made from polystyrene crosslinked with divinylbenzene (PSDVB).
Diameters of 200μm and larger are packaged as dry spheres. Packages are lot-numbered for convenient technical service and support after the sale.
Applied Physic has its own engineering, production, and metrology facilities for better quality control and response to customer needs. In addition to this line of polymer size standards, we also offer calibration standards in silica and glass materials. Ask our technical service department for information about specific applications or other product needs not listed here.
Certificate of Calibration and Traceability to NIST, which includes a description of the calibration method and its uncertainty; Table of chemical and physical properties; Material Safety Data Sheet
