Abstract
An improved device and method for liquid storage and analysis. The device comprises a receptacle defining a U-shaped compartment for a first open-ended branch and a second closed branch. A reaction zone in which the liquid will react with a reagent during analysis is located at the bight interconnecting the branches. The opening in the first branch constitutes a liquid inlet. A wall portion of the second branch spaced from the reaction zone is of self-sealing material which is punctured to release gas from the compartment and to aspirate liquid into the first branch. The material subsequently forms a fluid-tight seal. A wall portion of the body adjacent the reaction zone is made of light-permeable material so that the reaction or the result of the reaction can be optically analyzed. A plurality of such compartments can be provided with a chamber interconnecting the extreme ends of the second branches. A common wall portion of self-sealing material can then be provided for some or all of the compartments.
