  • Publication number: 20250186991
    Abstract: A pipette tip line for use with a pipette includes at least two pipette tips. Each of the at least two pipette tips includes a tip opening at a lower end, a collar at an upper end defining a mounting opening, and a seat region defined on an inner circumference of the collar and configured to be clamped onto a neck of the pipette. The height of the collar varies between the at least two pipette tips and the seat region matches a contour of a pipette. The at least two pipette tips are configured to be clamped by the seat region onto a same area of the neck. The collar of each of the at least two pipette tips projects upward along the neck at varying heights. The at least two pipette tips include two different types of pipette tips.

  • Patent number: 12325018
    Abstract: A pipette comprises a pipette housing, a neck configured to clamp on a pipette tip, and a drive apparatus. The drive apparatus comprises a drive element configured to displace a displacement element to draw a liquid sample into the pipette tip and to eject the liquid sample from the pipette tip. A scanning apparatus comprises a scanning element positioned proximate the neck and configured to be displaced relative to the pipette housing by a collar of the pipette tip when clamping the pipette tip onto the neck. A mechanical display apparatus is coupled to the scanning apparatus and comprises a display. When the pipette tip is clamped to the neck the scanning apparatus is configured to adjust the display depending on a height of the collar of the pipette tip relative to the neck, and the neck is configured to accommodate different collar heights.

  • Patent number: 12044691
    Abstract: A measuring apparatus usable in a liquid handling apparatus, and method, for detecting a deformed pipetting container using a first and a second measuring device, the measuring apparatus being configured to determine the position of an end region of the pipetting container as a f unction of a position of a measurement support section of the pipetting container as relative position data in a data storage device, so that subsequently the position of the end region of the pipetting container can be determined by measuring the position of the measurement support section and from the relative position data.

  • Patent number: 11980882
    Abstract: Provided is a handheld fluid transfer apparatus, more particularly a pipette or repeater pipette, and a laboratory system comprising the handheld fluid transfer apparatus, which comprises: a control apparatus, which comprises a data processor capable to execute a control program for controlling at least one electronically controllable function of the handheld fluid transfer apparatus using input data, a user interface device for receiving a user input, the user interface device comprising a motion sensor device for measuring motion data of the handheld fluid transfer apparatus and for providing at least one motion data sequence, which contains subsequently measured motion data, a motion data memory for storing the at least one motion data sequence, an evaluation device being configured to determine the input data in dependence on the evaluation of the at least one motion data sequence. A method is provided for operating the fluid transfer apparatus or the laboratory system.
