A liquid aspirating and dispensing apparatus and method of using the apparatus. Among other elements, the apparatus includes a liquid handling device having one or more channel members, each of which has a removable liquid holding tip attached, and a signal transmitting device. A signal transmitted from the signal transmitting device may be used in a variety of ways to yield information regarding the performance of the apparatus. This information may be provided via direct detection of the signal by an operator of the apparatus. Alternatively, the signal may be detected by a programmable signal detecting device, interpreted by the apparatus, and then displayed in a form that is understandable to the operator. Furthermore, the liquid holding tip may be modified to enable different forms of signal transmission.

Apparatus and method for aspirating and dispensing liquid

An air displacement liquid delivery system including a liquid delivery device, one or more sensors, a control unit, and a preprogrammable computing device, and a method for using the air displacement liquid delivery system. The one or more sensors are capable of obtaining information regarding conditions within and external to the liquid delivery device and sending this information to the control unit and/or the computing device. In turn, the control unit and/or computing device are capable of using this information to calculate one or more properties of gas contained within, and the air external to, the liquid delivery device, and one or more properties of a liquid that is to be aspirated or dispensed by the liquid delivery device. The system may optimally control the performance of the liquid delivery device based upon any one or more of these calculated properties.

Air displacement liquid delivery system and related method

Pipettes, widely used in clinical and pharmaceutical laboratories to transfer small volumes of liquid, may be subject to hidden performance degradation and operator error. Pipette performance cannot be accepted without monitoring. The present disclosure concerns a verification device for a pipette with a piston for aspirating then dispensing, using a shaft, a determined volume of liquid. This device may include: a first assembly for supplying a displaced volume measurement, comparing this measurement to a desired value and generating an indication of the difference between the measured volume and the desired value; and a second assembly, responding to the first assembly, for delivering information relating to the indication.
