Pipette for dispensing successive volumes of liquid

摘要: The invention relates to a pipette for dispensing successive volumes of liquid by repeated action on pusher (22). A drive lever (26) is provided pushrod (15) and piston rod (5) downwards only. extends transversely the longitudinal axis (X) thrust it includes hole (27) through which passes with small amount clearance. (22) can act one end cause tilt relative then wedging, together (5), expel predetermined volume liquid. mounted rotate about (Y) that intersects perpendicularly substantially halfway along hole.
