Biochemical analysis apparatus for incubating and analyzing test sites on a long tape test film

摘要

A biochemical analysis apparatus comprises a sample accommodating region, an accommodating region for test films containing a reagent which reacts with a liquid sample to give rise to a change in optical density, and a conveyor for sequentially pulling out each test film from the test film accommodating region. An applicator takes up the liquid sample from the sample accommodating region and applies it to the test film at the position to which the test film has been pulled out. An incubator incubates the sample-applied film portion for a predetermined time, and a detector measures the optical density of the sample-applied film portion during or after the passage of the predetermined time. The conveyor, the incubator and the detector are provided to correspond to each of the test films, and a movement device moves the applicator to apply the liquid sample to the test films.
