Abstract: A method for dosing a liquid using a pipette with adjustable dosing step size and an indicating equipment and a syringe that can be operated using the pipette. The syringe is detachably connected to the pipette. The dosing step size is set, or the dosing step size set before is maintained. The dosing volume adjusted via the dosing step size is indicated. Liquid is aspirated into the syringe. Dosing steps are performed, counted and the number of performed dosing steps and/or the number of dosing steps still possible without refilling the syringe is determined and indicated. After performing the maximum number of dosing steps possible without refilling the syringe, either the syringe is detached, or the steps are performed again.

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.
