Particle Analyzers
Polysciences, Inc. Nanobead NIST Traceable Particle Size Standard, 100nm, 15 mL
Precision Size Standards are offered in three size groupings: Nanobead, Microbead, and Megabead. They are measured on in-house instruments calibrated with NIST (National Institute of Standards and Technology) Standard Reference Materials. Each product is supplied with a Certificate of Analysis documenting traceability to NIST Standard Reference Materials. The size, standard deviation, coefficient of variation, and lot number are printed on the label for easy reference.
Polysciences, Inc. Fluoresbrite YG Microspheres 20.0 um
Fluoresbrite Yellow Green Microspheres have excitation and emission spectra similar to FITC with excitation maxima of 441nm and emission maxima at 485nm. They are one of the brightest microspheres available at this wavelength and are used extensively in phagocytosis studies, flow cytometry and diagnostic assays.
Polysciences, Inc. Polybead Microspheres 6.00 um, 5 mL
Polybead Microspheres are monodisperse polystyrene microspheres available in sizes from 50 nm to 90 um. Diameters 4.5 um and larger are crosslinked with divinylbenzene (DVB). Our experienced chemists control the synthesis to provide precise monodisperse particle size distributions. These particles contain a slight anionic charge from sulfate ester.
Ted Pella Inc Unconjugated Gold Sols-Gold Colloids, 10NM, 100 mL
The nanometer sized gold colloids can be characterized as follows: Monodispersed gold nanoparticles supplied in water, having trace amounts of citrate, tannic acid and potassium carbonate. Citrate stabilized with a net negative surface charge. Gold colloid pH's range from above 5 for 5nm gold to less than 9 for the larger sized particles (pH increases with size). Available in a size range from 5 to 250nm. The particles are invaluable tools for light scattering, either Raman or plasmon resonance.
