Abstract (en)
[origin: US4362063A] A device for sampling and dispensing adjustable volumes of liquid samples, with numerical display, is provided with a compact adjusting and display mechanism which comprises: an externally threaded sleeve which screw threadedly engages with the device housing; a prismatic control rod whose profile ensures that it rotates with the sleeve; a bush equipped, removably, with a means of causing it to rotate with the control rod; and a plurality of volume-indicator drums mounted around said bush. The sleeve serves as an adjustable end stop for a reciprocable piston actuated by the control rod.
