Test apparatus for determining a metabolic characteristic of microorganisms

摘要

A tester can determine a metabolic characteristic of a microorganism suspended in a medium. The tester has a reagent supply, a probe, a dispenser and a controller. The reagent supply contains a quantity of at least one test reagent. The probe is sized to be inserted into the medium and for providing a reaction signal signifying the temperature of a fluid at the probe means. The dispenser is coupled between the reagent supply and the probe for delivering at the latter from the former a controllable amount of test reagent. The controller is coupled to the probe and to the dispenser for controlling the amount of test reagent dispensed by the dispenser and recording the variation of the reaction signal after delivery of the test reagent.
