Lot of three used glass absorbance cuvettes calibrated pathlengths

Description

This lot consists of three (3) USED windowed standard glass absorbance cuvettes plus three (3) loose fitting PTFE caps. The two necessary cuvette faces are transparent and polished as shown in the photographs; the rest and bottoms are frosted. The cuvettes are of unknown manufacturing provenance. They are in very good or better condition. The calibrated optical path lengths are 0.997, 0.998, and 1.001 cm, as shown on the bottoms of the cuvettes.
Although the cuvettes are fairly clean, as shown in the photographs, it should be assumed that they definitely need to be properly cleaned before use. It is strongly recommended that they be carefully and very gently cleaned: no ultrasonic bath or harsh cleaning agents.
