Abstract
A probe head used in robotic assays for transferring liquid in miniscule quantities. The probe head includes an array of liquid transferring needles which move as a unit with the probe head. As the needles contact a surface, high spots or other irregularities on the surface are accommodated by needle compliance to assure all needles ultimately touch the surface. Touching contact assures reliable liquid transfer.
