Patent number: 10962560Abstract: A pipetting arrangement includes at least two sets of pipettes (9a; 9b; 9c; 9d). Each set of pipettes (9a; 9b; 9c; 9d) is operationally connected, via a controllable ON/OFF valve (11a; 11b; 11e; 11d) to a common aspiration port (7). Latter is connectable to a pumping arrangement. The valves (11a; 11b; 11e; 11d) are controlled by a timing-control unit (15) conceived to establish, by control of the valves (11a; 11b; 11e; 11d), the operational connections of the at least two sets of pipettes (9a; 9b; 9c; 9d) to the aspiration port (7) in a time-multiplexed manner.Type: GrantFiled: March 13, 2018Date of Patent: March 30, 2021Assignee: Tecan Trading AGInventor: Pius Fink

Patent number: 7250767Abstract: A method for introducing a liquid sample into an NMR spectrometer to measure an NMR spectrum of the liquid sample, wherein the liquid sample is injected into a supply line and wherein further liquids are supplied into the supply line following the liquid sample, which are separated from each other and from the liquid sample by gas bubbles is characterized in that the liquid sample is supplied via an injection inlet to a valve configuration whose output side can be connected to the supply line and the further liquids and gas are supplied to the valve configuration via supply lines, wherein a desired sequence of sample segments, gas bubbles and further liquid segments is generated through temporally matched switching of the valve configuration in the supply line and is supplied to the NMR spectrometer. The inventive method realizes supply of a liquid sample into an NMR spectrometer with rapid sample transfer while thereby preventing mixing and dilution of the individual segments.Type: GrantFiled: June 6, 2005Date of Patent: July 31, 2007Assignee: Bruker Biospin GmbHInventors: Martin Hofmann, Pius Fink

Patent number: 6959836Abstract: The invention relates to a dispensing device and a method for dispensing liquids, preferably reagents, in an essentially automated and finely dosed manner. The dispensing device comprises a first duct that is connected to a storage element for storing the liquid to be dispensed. In addition, a conveying element for conveying the liquid through the fist duct is provided, whereby the liquid has to be dispensed. Liquid is transported from the storage element and is conveyed into the first duct by the conveying element. Moreover, the dispensing device is provided with a closing device that is arranged downstream in the conveying direction of the liquid in relation to the conveying element and serves for quickly closing and quickly opening the first duct. The aim of the invention is to regulate the pressure of the liquid in the region between the conveying element and the closing device. A device for regulating the pressure of the liquid in this region is provided.Type: GrantFiled: February 19, 2001Date of Patent: November 1, 2005Assignee: Qiagen-GmbHInventors: Michael Collasius, Konstantin Lutze, Pius Fink, Marco Di Berardino
