Abstract
An apparatus for dispensing small quantities of particles, the apparatus comprising a hopper (20) provided with a sieve at a bottom portion thereof, the hopper defining a powder-containing zone above the sieve which in use contains powder to be dispensed therefrom through the sieve, a support (25) for the hopper, the support holding a portion of the hopper so that the hopper can in use be held above a container into which the dispensed powder is to be received, at least one actuator (30) for delivering impact energy to the hopper for causing powder to be dispensed through the sieve when the hopper receives the impact energy, and an element which is adapted to permit controlled vertical movement of the hopper relative to the support.
