Abstract: An apparatus useful for measuring the optical properties of a liquid which comprises a cylinder having at least a portion thereof constructed of a transparent material, inlet means at one end of said cylinder for introducing liquid into the cylinder, outlet means at the other end of said cylinder, a piston slidably mounted in said cylinder to define a first portion and a second portion in said cylinder, said first portion being adjacent to said inlet means, a passageway through said piston communicating with said first and second portions and with said outlet means, a valve means positioned in said passageway and adapted to close said passageway when the volume of said first portion is increased by movement of the piston and to open said passageway when the volume of said first portion is decreased by movement of the piston. The apparatus permits reliable measurement of the transparency to light of light samples in the chamber by keeping the walls clean so that the light for one sample does not contaminate or otherwise affect a sample likewise subsequently drawn in.
