Abstract

An apparatus responsive to optical changes in a waveguide when the latter is contacted with an analyte capable of reacting with a specific reactant thereto attached to the surface of said guide involves, for containing the analyte, an interchangeable round bottomed cuvette temporarily held by a suitably shaped carrier in working relationship with the optical components of the apparatus, this arrangement ensuring a correct optical orientation thereof relative to said component whatever the exact positioning of the cuvette.
