APPARATUS FOR MEASURING THE LIGHT PASSING THROUGH A LIQUID SAMPLE IN A CLOSED FLEXIBLE WALLED CHAMBER

摘要

A device for measuring a concentration of a liquid sample in a flexible chamber for containing the sample where a portion of the chamber is defined by a measuring zone including, an operating station having a photometer where pressurizing force means are applied to the chamber to alter the chamber configuration forcing the liquid sample into the chamber area at the measuring zone causing intimate contact with a pair of spaced fixed plates of the photometer to provide for a predetermined sample thickness for measurement purposes.
