Abstract

The disposable analytical device includes an outer shell portion having an interior which is divided into reagent chambers and a test sample chamber. The reagent chambers are non-communicable with each other. However the test sample chamber is communicable with each of the reagent chambers through a semi-permeable membrane. The device is formed of an optic quality material to permit analysis of the test results in a spectrophotometer.
