Abstract (en)
[origin: WO8304015A1] Method and apparatus to dispense, pipet and, afterwards, to dilute fluids, primarily for analytical laboratory use. In the method of this invention, a constant stream of the fluid is established and maintained in a part of a tube by means of a peristaltic pump, and a predetermined amount of the fluid is sipped or dispensed by opening a suction or pressure side of the tube for an adequate time. With the apparatus, pressure side tubes of the pump are connected through controlled switch valves to fluid container or to a dispensing tube, and a control unit is attached to the switch valves and is electrically connected to a sensor of a chopper fixed to an axis of the pump.
