8 boxes with 26 cuvettes.   8 glass, and 20 quarts 

20 cuvettes of QS (Quartz Glass High Performance): This indicates that the cuvette utilizes a high-purity, homogeneous quartz glass, sometimes referred to as synthetic quartz glass. Cuvettes with this designation are designed for applications requiring high optical transmission, particularly in the UV range (200 nm - 2500 nm).

8 cuvettes S (Quartz Glass): The "S" designation usually refers to a standard grade of quartz glass. While it still offers good UV transmission, it may not provide the same level of purity or homogeneity as the "QS" grade.
