Disposable cuvets have long replaced cuvets once normally made of glass. New plastics coupled with modern methods of production allow photometric measurement well into the UV range.
Ultra-precision molds with several cavities – one per cuvet – are used for producing ratiolab® Q-VETTES and ratiolab® CUVETTES under controlled room conditions. Thus, in any one injection molding run several cuvets are produced simultaneously. In order to prevent deviations in extinction coefficient values from occurring in any one run due to increased stray light, the cuvets are automatically sorted according to their numbered cavities of origin.
Each package shows the corresponding local production number of the cuvetts position in the net. So all cuvetts inside one styrofoam box are technical wise indentical. Any measurement done with those identical cuvetts insures a high accurancy.
The new generation of cuvets with clearly improved photometric properties. The optimized form and the small wall thickness of the cuvets provides increased heat transfer resulting in more constant sample temperatures during photometric measurements.
