Abstract
A photometer and a test sample holder, with the holder having a light-blocking, black upper section and a light-transparent, lower section test sample vial, for use with the photometer. The photometer includes an O-ring seal at an input, to the light measurement sample chamber, so on insertion of the holder, with a test sample to be detected in the test vial, the upper section blocks interfering light from the chamber.
