Abstract

A chemical assay system comprises at least one incubator having a plurality of slide receiving chambers each for receiving a chemical assay slide. The chambers are arranged in a row so that the chemical assay slides received in the chambers are arranged in a row in one plane and each chamber is provided with an opening for exposing the chemical assay slide received therein. A probe for projecting light onto the chemical assay slide and measuring the intensity of the light reflected from the chemical assay slide is provided to be movable along the row of the chemical assay slides to positions in front of one of the openings of the slide receiving chambers.

Claims

1. In a chemical assay system comprising at least one incubator having a plurality of slide receiving chambers each for receiving a chemical assay slide, the chambers being arranged in a row so that chemical assay slides received in the chambers are arranged in a row in one plane and each chamber is provided with an opening for exposing a chemical assay slide received therein;

a slide insertion means for inserting chemical assay slides into the slide receiving chambers; and

a probe means for projecting light onto a chemical assay slide in each slide receiving chamber and measuring the intensity of the light reflected therefrom, the probe means being movable along the row of the slide receiving chambers to measuring positions in front of each of the openings;

the improvement which comprises said slide insertion means being movable bi-directionally with respect to the incubators such that any slide can be inserted into said slide receiving chambers independently of any other slide.

2. A chemical assay system as defined in claim 1 in which said probe means is driven by a linear motor.

3. In a chemical assay system comprising at least one incubator having a plurality of slide receiving chambers each for receiving a chemical assay slide, the chambers being arranged in a row so that chemical assay slides received in the chambers are arranged in a row in one plane and each chamber is provided with an opening for exposing a chemical assay slide received therein;

a slide insertion means for inserting chemical assay slides into the slide receiving chambers; and

a probe means for projecting light onto a chemical assay slide in each slide receiving chamber and measuring the intensity of the light reflected therefrom, the probe means being movable along the row of the slide receiving chambers to measuring positions in front of each of the openings;

the improvement which comprises said slide receiving chambers and slide insertion means being arranged so that chemical assay slides are respectively and independently inserted into and discharged from each of the slide receiving chambers and wherein said probe means is replaced by a fixed optic scanner having a plurality of parallely disposed optics probes that are fixed in place and selectively activated to scan a respective slide and to measure the density of the light reflected from the chemical assay slide.
