| 20120104040 | AIR DISPLACEMENT LIQUID DELIVERY SYSTEM AND RELATED METHOD - 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 it 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. | 05-03-2012 |
| 20110126645 | APPARATUS AND METHOD FOR ASPIRATING AND DISPENSING LIQUID - 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. | 06-02-2011 |
| 20100290048 | QUANTITATIVE DUAL-DYE PHOTOMETRIC METHOD FOR DETERMINING DILUTION IMPACT - The invention provides ways to determine the impact of diluting a solution wherein the diluting may be carried out for any of a variety of purposes. In one embodiment, the method enables accurate volume dispensation calculations independent of meniscus shape. In another embodiment, the method enables accurate determination of plate washing efficiency. In yet another embodiment, the method enables the accurate determination of dilution ratio over a plurality of dilution steps. The methods described may be carried out using one or more systems arranged to perform the steps. A kit of the invention includes instructions for carrying out the steps of the methods and, optionally, one or more solutions suitable for conducting photometric measurements. | 11-18-2010 |
| 20090251681 | SYSTEM AND METHOD FOR LIQUID DELIVERY EVALUATION USING SOLUTIONS WITH MULTIPLE LIGHT ABSORBANCE SPECTRAL FEATURES - A system and related method for improved liquid delivery evaluation using a solution containing one or more dyes such that the solution exhibits multiple distinct detectable light absorbance spectral features for calibrating or testing over extended volume or dilution ranges are described. The system includes: a photometric instrument capable of measuring optical absorbance at multiple wavelengths; one or more sample solutions to be dispensed using the liquid delivery system whose performance is being tested or calibrated; and vessels optionally pre-filled, or filled by the user, with diluent solution. The sample solutions contain one or more dyes, chosen so that multiple distinct detectable light absorbance spectral features, such as peaks and/or valleys and/or plateaus of the solution can be distinguished for volume or dilution ranges of interest. The concentrations of the dyes may be chosen so that a large volume delivery device is calibrated using a spectral feature in the solution with a low absorbance per unit pathlength, while a small volume delivery device is calibrated with the same sample solution but using a different spectral feature with a high absorbance per unit pathlength. | 10-08-2009 |
