• This series of NIST traceable size standards provides an accurate and convenient method for calibrating or checking the performance of laser particle counters used in cleanrooms and other contamination monitoring applications. The products are suspensions of monodisperse polystyrene spheres (PSL) for use in airborne or liquid particle dispersion systems. They are available in a range of sizes from 0.1 to 100µm in diameter. The particles are prepared as low residue aqueous suspensions for minimal background interference, packaged in 15mL dropper-tipped vials. The particle diameters are calibrated by electron or optical microscopy. Each package includes a Certificate of Calibration and Traceability to the National Institute of Standards and Technology (NIST). In comparison with the well established 3000 and 4000 Series products described elsewhere, these product lines are precisely diluted for immediate use in laser particle counters with minimal time-consuming adjustments of concentration.
  • These uniform microspheres are NIST-traceable by calibration methods such as optical microscopy. Products from 1 to 160µm in diameter are packaged as aqueous suspensions of polystyrene spheres in dropper-tipped bottles. Diameters of 200µm and larger are packaged as dry spheres in screw-capped bottles. These larger particles are composed of polystyrene DVB (divinylbenzene). The spheres have a density of 1.05g/cm3 and an index of refraction of 1.59 @ 589nm.
  • Multiplex array analysis is a powerful technique enabling the simultaneous detection and quantitation of multiple analytes in a single sample. Using color coded microspheres, these tests can be carried out at flow cytometers. Cyto-Plex microspheres provide up to ten levels of red fluorescent intensities for analysis of ten different analytes. The Cyto-Plex microsphere kits consist of uniform particles with fluorescence intensities that are completely separated from each other. The microspheres are all the same size and have high-density carboxylated surfaces, providing very low non-specific binding and a consistent, uniform surface for coupling of a wide variety of anitbodies, nucleic acids and other biomolecules. Cyto-Plex microspheres have maximum emission at 700 nm, and can be excited with either 488 nm or 633 nm. Emission can be collected in 650 – 670 nm detector. Since there is little or no emission in FL1 and FL2, probes utilizing either of these channels can be effectively used as reporters.
