Description
- Achieve high visual contrast with Thermo Scientific™ ChromoSphere™ Dry Dyed Particles, polymer particles that are internally and deeply dyed in intense red or black, resulting in very high contrast and visibility relative to most background materials
- Available as dry powders that can be easily suspended in aqueous media, the product line consists of a large assortment of uniform, red or black particle sizes between 50μm and 500μm
- Particles are available in nominal diameters ranging from 50μm to 500μm
- The particles are made from cross-linked polystyrene divinylbenzene (PS-DVB) copolymer and should be stored at room temperature
- They can be 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 will occur when the 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
- Recommended for: Visualizing and inspection testing.
