摘要： The present invention is related to a microfluidic device capable of conveying a liquid by capillary forces. The microfluidic device comprises a microfluidic channel system comprising i) a liquid supply compartment; ii) a first channel connected to the liquid supply compartment, having at least one non-closing valve located downstream of the liquid supply compartment; and iii) a second channel. The second channel branches-off from the first channel downstream of the liquid supply compartment but upstream of the at least one non-closing valve and which re-unites with the first channel at the location of the non-closing valve to form an outlet channel. The second channel does not contain any non-closing or closing valve thus creating an unobstructed liquid flow path connecting the liquid supply compartment with the outlet channel.

摘要： A level sensor apparatus is disclosed for detecting contact of a pipetting needle with a liquid contained in a vessel. The apparatus includes a sensor head made up of a pipetting needle, a needle holder, and an electromechanical transducer. The sensor head also has an associated mechanical resonance frequency. An electrical signal generator is used to generate a driving signal which when applied to the electromechanical transducer causes vibration of the pipetting needle at the resonance frequency. A measurement device is used to measure a parameter of a vibration signal indicative of the mechanical vibration of the pipetting needle when it is driven by the driving signal. An electronic circuit and associated computer software is provided to evaluate variation of the vibration signal with time and thus detect contact of the pipetting needle with a liquid contained in the vessel.
