  4000 Series - Monosized Microsphere Size Standards


Excellent for use with any application that requires a NIST traceable size standard with a very narrow standard deviation.
   Product Detail


The mean diameters of these products have been calibrated with Thermo Fisher Scientific's NIST traceable microscopy methods. Their size distribution and uniformity are measured by electrical resistance analysis or optical microscopy. 4000 Series products from 1 µm to 160 µm are made from polystyrene (PS). 4000 Series products from 200 µm to 1000 µm are made from polystyrene crosslinked with divinylbenzene (PSDVB), except for the two largest products, which are made from polymethylmethacrylate (PMMA).

Spheres are used instead of irregularly shaped particles to minimize the response of analytical systems to shape effects. Products from 1 to 160 µm are packaged as aqueous suspensions in 15 mL dropper-tipped bottles, at an optimum concentration for dispersion, handling and dilution. Diameters of 200 µm and larger are packaged as dry spheres.

Each package of standards contains a Certificate of Calibration and Traceability to NIST which includes a description of the calibration method and its uncertainty, and a table of chemical and physical properties. A Material Safety Data Sheet, with handling and disposal instructions, is also included. Packages are lot-numbered for convenient technical service and support after the sale.

Thermo Fisher Scientific 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.
