Capvette and method of measuring optical density

Abstract

A capvette for the optical examination of liquids comprises a cuvette component having a rectangular or square basal surface with four side walls terminating into an aperture, wherein said aperture is in communication with a sealable cap component comprising an opening for fluid passageway from a container into said cuvette component. The capvette and container combination, as a single unit allows reaction of fluid or growth of microorganism and measurement of optical density at desired time intervals. A direct method of measuring optical density comprises simply inserting the cuvette component of the capvette into a spectrophotometer.
