First Claim
Patent Images
1. A method of measuring the turbidity of gas-containing liquid mediums with microorganisms, comprising the steps of establishing a fluid-communication path between a vessel and a measuring chamber;
- drawing a sample of the medium from said vessel into said measuring chamber;
measuring the turbidity of the drawn sample outside said vessel after gas bubbles in the drawn sample have escaped from it;
thereafter reintroducing the drawn sample from said measuring chamber into said vessel; and
thereafter sterilizing said vessel, said path and said measuring chamber simultaneously and together prior to introduction of the new medium into the vessel and without interruption of said paths.

Abstract
From a vessel in which micro-organisms grow in a liquid medium containing gas bubbles, a sample is withdrawn into an exterior measuring chamber by means of suction. Gas bubbles are allowed to escape from the sample and thereafter the opacity or turbidity of the sample is measured by passing a light beam through it.
