AbstractA specimen chamber comprising a central chamber element sandwiched between a base plate and a cover plate, which base plate and cover plate secure cover slips within recessed areas on opposite surfaces of the central chamber portion which face the base and cover plate. The central chamber element includes a central flow passage, which terminates at opposite ends into tee channels. The sandwiched arrangement of the elements is secured by locking pins, which are insertable into alignment post elements that extend from the base plate though the central chamber element and the cover plate. The locking pins include a plurality of locking cams.
