Abstract
A lockable valve mechanism for introducing a liquid sample into an associated reaction vessel includes a valve body, and a valve member rotatably mounted thereon. The valve member is movable from an open position, wherein inlet and outlet passages of the valve mechanism are aligned for introduction of a sample into the reaction vessel, to a closed and sealed position, wherein the outlet passage of the valve body is sealed. The valve member includes a locking arrangement to prevent movement of the valve member out of the closed and sealed position after movement from the open position into the sealed position.
