Abstract
A modular reaction cassette has a fluid metering mechanism and valves for releasing fluid which are actuated by various centripetal acellerations generated in an automated patient analysis instrument having a variable speed rotor. Various geometries and sealant materials are used to select the rotational speed at which the sealant material yields to operate the metering device and release valves.
