Patent number: 9335200Abstract: A device for detecting a phase boundary in a liquid tank a sensor that can be advanced in the direction of the phase boundary in the liquid tank. A circuit processes an output signal of the sensor to detect a change in capacitance and has a first channel with a first filter module to filter out a first signal having a short pulse width from the output signal and a second channel having a second filter module to filter out a second signal having a greater pulse width from the output signal. A controller module with comparator module determines whether the first signal reaches a first threshold value and a processing module determines whether the second signal meets predefined second signal criteria.Type: GrantFiled: December 22, 2010Date of Patent: May 10, 2016Assignee: TECAN TRADING AGInventors: Nicolas Cors, Markus Schoni, Markus Wiggli, Adi Zuppiger

Patent number: 9302265Abstract: An inlet valve charges an inner chamber with liquid and has a first axis and an inlet opening with a tool that automatically recloses. The inlet valve has a valve body with a blocking element, and a pressing part; a valve space enclosing the valve body at least partly; a spring mechanism and a sealing element. An open passage region opens into the liquid passage of the pressing part and into the valve space. The spring mechanism presses a sealing surface of the blocking element against the sealing element in a closed position of the valve body. The valve body of the inlet valve can be brought to an open position by pressing the pressing part against the resistance of the spring mechanism. Chamber systems and sample containers with such inlet valves are also disclosed.Type: GrantFiled: September 1, 2015Date of Patent: April 5, 2016Assignee: TECAN TRADING AGInventors: Nico Birkner, Thomas Iten, Marina Knoppke, Markus Wiggli

Patent number: 8119080Abstract: A liquid handling system has a robot manipulator for orienting pipette or dispenser tips in relation to sample containers situated in or on the system, pipette or dispenser tips, drives for moving the robot manipulator, and processors for controlling the movements and actions of the robot manipulator and/or of the pipette or dispenser tips. The system also includes at least two blocks situated on two arms of the robot manipulator, at least two of the pipette or dispenser tips being situated on each block and at an axial distance to one another. The axial distance essentially corresponds to the grid spacing of wells of a microplate. At least one of these blocks, for the alternating interlaced orientation of the pipette or dispenser tips of at least two blocks along a shared line, are individually movable at least in the X direction. A method allows the time-saving pipetting over of liquid samples between diverse sample containers, e.g., between sample tubes and microplates having 24, 96, 384, or 1536 wells.Type: GrantFiled: July 15, 2009Date of Patent: February 21, 2012Assignee: Tecan Trading AGInventors: Markus Wiggli, Fred Schinzel, Bronwen Forster
