Abstract: 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.

Abstract: Disclosed is a process and apparatus for the catalytic hydrogenation of fluoro-olefins to fluorocarbons where the reaction is carried out in a multi-tube shell and tube reactor. Reactions involving hydrogenation of fluoro-olefins are typically exothermic. In commercial processes where a fluoro-olefin CnH2n?xFx to CnH2n?x2Fx is hydrogenated (e.g., hexafluoropropylene to 236ea, 1225ye to 245eb, and the like), inadequate management or control of heat removal may induce excess hydrogenation, decomposition and hot spots resulting in reduced yields and potential safety issues. In the hydrogenation of fluoro-olefins, it is therefore necessary to control the reaction temperature as precisely as practical to overcome challenges associated with heat management and safety.

Abstract: 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.
