Embodiment Construction

[0015] The pipette of the present invention includes an electronic volume display and an associated control system and user interface. When the pipette is calibrated, the (at least one) real volume obtained by measurement, corresponding to the displayed volume, is input into the control system via the user interface. The control system calculates and then stores the calibration settings, and, during subsequent dosing, the piston stroke or the displayed volume is corrected according to these settings so that the dosed volume is equal to the displayed volume with the highest accuracy. This way, the person performing the calibration does not have to calculate these settings, reducing the workload and eliminating the risk of calculation errors. The pipette is preferably calibrated with several, especially two, volumes. Preferably said display is a "full graphics display".

[0016] The pipette preferably enables the set volume to be varied, but the invention is also applicable to...

Abstract

The invention concerns a calibration pipette comprising an actuated electronic display (3) and a calibration function. The calibration function is such that at least one real volume obtained with an indicated volume is input via a user interface into the control system and that the control system calculates calibration settings and stores them in a memory, by means of which settings the stroke length of the piston or the volume indicated on the display is corrected so that the volume indicated on the display equals the real dosing volume.

Description

technical field [0001] The invention relates to a pipette intended for the dosing of liquids and comprising: an electronic system for displaying the pipetted volume and a device allowing the input of calibration data to the operating system User Interface. The invention is particularly concerned with this calibration function. Background technique [0002] Pipettes used in laboratories for dosing liquids include a piston that is movable within a barrel to draw liquid into a tip receptacle attached to the barrel. There are also electronic pipettes whose piston is driven by a motor and associated control system. However, there are also electronic pipettes in which the piston is driven manually and which comprise an electronic display for indicating eg the pipetted volume. Electronic pipettes have a user interface for selecting eg a desired pipetting function, for setting the volume of a variable volume pipette, and for giving instructions for performing operations. The use...
