Compared to glass and quartz cuvettes made of polystyrene, adsorption of pigments is considerably suppressed.
This doubles the number of assays for a single dye or reagent and reduces the cost per assay.
The cuvette can be used in place of a test tube, eliminating the need to transfer samples from the test tube by using the protein assay standard method with 0.05 mL of sample and 2.5 mL of staining solution, and the DC protein assay standard method with 0.05 mL of sample, 0.25 mL of reagent A (or reagent A '), and 2.0 mL of reagent B.
