Cole-Parmer 00295-16 Fluorescent Fwt Red Dye Tablet (200 pcs)

Dyes diffuse rapidly in water, producing a vivid, easy-to-see color. Excellent for identifying diffusion and dispersion patterns, rates of flow, discharge locations, seepage areas, sea marking, and more.

Fluorescent red dye (rhodamine WT) is noncarcinogenic. Ideal in yellowed water or water with heavy algae growth. Use an ultraviolet lamp (order separately) to trace fluorescent red dyes where normal visual detection is difficult. Minimum detectable concentration of all dyes in clear water is 1 ppm.

• Biodegradable and nontoxic
