    摘要: Colorimeter cuvettes in the form of sealed transparent flexible plastic envelopes containing or adapted to receive samples of substances to be colorimetrically analyzed. Means are provided for introducing sample reagents into the envelopes. Mixing of the envelope contents may be effected by kneading prior to testing and the flexibility of the cuvettes allows for adjustment of optical path lengths therethrough.
