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.

Contents & Storage

Store at room temperature. Keep bottle tightly sealed to avoid contamination.
