Abstract
A device for automatically timing and recording the sedimentation rate of fluid samples contained in cylindrical, transparent test tubes includes a generally rectangular rack having flat vertical walls formed with cylindrical bores for receiving the test tubes, and vertical channels at outer sides of the walls for receiving photographic strips. A lamp inside the rack shines through test tubes to the strips to record the amount of sedimentation of the fluid. The walls of the rack may be transparent for passing light therethrough or may be provided with slits at inner sides thereof for communicating with the bores. The bores communicate with the channels via other slits formed at outer sides of the bores. A rectangular housing may be fitted over the rack to exclude ambient light.
