Abstract

Apparatus and method for automatically detecting the increase in opacity of a liquid in a container 3a by shining a light 1 through the liquid onto a photo-electric cell 4, the cell output being automatically monitored. Useful for detecting the growth of micro-organisms in a well in a transparent multi-well plate, 3. Light may be distributed from a common source 1 by light guides 2 to respective wells 3a, the optical transmission being measured by respective photo-electric cells 4. The optical transmission of a well containing a test material may be compared with that of a well containing a control material by arranging relative motion between the wells and a combination of a common source and photocell, so as to provide sequential measurements. <IMAGE>
