An apparatus for sequentially picking up small elements one at a time comprising a hollow needle having an opening near its free end, and a tube sliding over the needle in a rapid oscillating motion to dislodge unwanted elements clinging near the needle opening. The apparatus can move between a position in which the needle is connected to a vacuum source dips into a receptacle to pick up one of the elements contained in the receptacle and a position in which the needle is connected to a pressure source allows the element to drop to a reception position.
