A dispensation device having a nozzle defining a chamber and a dispensation orifice which communicates with the chamber. A transfer pin is moveably received within the chamber and moveable between a retracted position and a dispensing position. In the dispensing position, a portion of the contact end extends out of the chamber through the dispensation orifice. A driven element contacts the transfer pin, with the drive element magnetically coupled to a driven element. A drive element is oriented to magnetically move the driven element and thus magnetically position the transfer pin.
