Abstract

Method for detecting pipetting tips in a laboratory automation apparatus including an electrode and reference electrode providing a capacitive sensor. A pipette tray holding pipetting tips is located on a working table between the electrode and the reference electrode. The pipette tray includes passages organized in a matrix. The pipetting tips have a proximal collar coupled to a pipetting tube and the tubes are received in the passages with the top surface of each collar vertically distanced from the top surface of the tray. The electrical conductivity of the tray differs from the electrical conductivity of the pipetting tips. The method includes scanning the tray by relative movement between the tray and the electrode while an input signal is directed to the capacitance sensor and receiving a feedback signal from the sensor to detect a change in capacitance related to the presence or non-presence of pipetting tips in the tray.
