Abstract
Described is a powder dispensing apparatus for dispensing a powder, comprising: a dispensing chamber for dispensing a predetermined volume of powder to a receptacle; an inlet valve movable between a closed state and an open state to control ingress of powder into the dispensing chamber from a powder source; an outlet valve movable between a closed state and an open state to control egress of powder from the dispensing chamber to a receptacle. The inlet valve and outlet valve are individually actuated between the closed state and open state by a common removable handle. The inlet valve and outlet valve each comprise an interlock for receiving and engaging the handle. The interlock is configured to receive and release the handle when the respective valve is in the closed state and engage the handle so as to prevent removal of the handle when the respective valve is in the open state.
