Abstract
An a.c. operated photoelectric turbidity comparator which has been found useful in assaying physiologically active substances by measuring the growth of micro‐organisms is described. A special feature is that the power supply for both the amplifier and the light source is electronically stabilized.This publication has 6 references indexed in Scilit:
