Each cuvette is secured in its own individual compartment inside a dust resistant styrofoam tray to assure scratch-free optical surfaces. 10 mm light path and accurate to /-2%. Polystyrene cuvettes transmit between 75-80% of light energy from 380-800nm and are useful to 240nm, where over 70% of the light energy is transmitted.

Manufactured from optically clear polystyrene for superior clarity and transmission. These spectrophotometry cuvettes fit most spectrophotometers, including Beckman, Perkin-Elmer, Gilford, Hitachi, Varian and Shimadzu. Double-seal leak-proof caps sold separate.
