Apparatus for testing sedimentation rates of liquids

摘要

The apparatus consists of at least one test-tube carrier defining seats for test tubes. The carrier is moved by oscillation or rotary motion about a horizontal axis under the influence of time control means. A structure which is vertically movable relative to the test tubes is fitted with individual means for the photometric observation of the data relating to each test tube and is controlled by time-control means. Processing and recording means collect data relating to the presence of each test tube, the presence of a sample, and the level of said sample, for each test tube seat.
