Programmable automated turbidimeter/colorimeter

摘要

A programmable automated turbidimeter/colorimeter system for accurately measuring growth among multiple bacterial specimens is described which in a preferred embodiment includes a motor driven rotatable carousel assembly disposed within an aluminum housing, the carousel assembly including a plurality of evenly spaced peripheral holes for receiving a corresponding plurality of disposable culture test tubes, a light source and a light detector disposed in spaced confronting relationship to each other whereby the culture tubes pass therebetween, and a signal amplifier and a recorder for recording optical densities of each specimen as the carousel is continuously rotated. A concentric magnetic shield may be disposed on one side of the carousel for shielding experimental specimens from control specimens in measurements of magnetic effects on the cultures.
