Abstract
A dispenser for dispensing measured amounts of powder for use in automated sample handling. The dispenser includes a cylindrical housing having a central cavity with an axial opening into the cavity at one end of the housing and a relatively narrow passage from the cavity leading out of the cylindrical housing through a nozzle at the opposite end thereof. A powder containing vial is removably mounted on the cylindrical housing. A radial passage through the cylindrical housing connects the vial with the narrow passage to discharge powder out through the nozzle. The cylindrical housing is rotatable supported on a mount through which extends a driven shaft. The driven shaft includes a worm drive located in the relatively narrow passage. A drive belt is provided to oscillate the cylindrical housing and the powder reservoir.
