Abstract

A chemical analyzer includes a transport mechanism having a rotatable turntable adapted to hold a plurality of reagent test slides, a sample metering device, an incubator or temperature controller, a reflectometer and associated electronics and software. The rotatable turntable preferably holds up to twelve slides about its circumference, which slides are loaded onto the turntable by an inserter mechanism. The turntable positions the reagent test slides under the metering device, which device deposits a predetermined amount of sample onto each slide. The turntable also carries the slides above a reflectometer. After testing has been completed, an ejector mechanism automatically removes the reagent slides from the turntable.
