Description
Achieve high visual contrast with Thermo Scientific™ ChromoSphere™-T Certified Size Standards, colored polymer microspheres with NIST™-traceable diameters. These reference and calibration materials are used in the testing of filtration systems, vial cleaning evaluations, contamination control studies and calibration of injection devices.
- Internally dyed with deeply colored red or black dyes, resulting in very high contrast and visibility relative to most background materials
- Mean diameters traceable to the standard meter through the National Institute of Standards and Technology (NIST)
- Calibrated by optical microscopy
- Made from cross-linked polystyrene divinylbenzene (PS-DVB) copolymer
- Available as dry powders
- Easily dispersed in aqueous media with the aid of a small amount of surfactant or in lower alcohols, such as methanol or ethanol
- Minimal dye extraction when particles are suspended in pure alcohols
- Other organic solvents, such as ethers or chlorinated hydrocarbons, should be avoided because they will swell the particles and completely extract the dye.
