摘要： A substrate orientation device includes a frame that supports a substrate on which liquid is dispensed, for example as may relate to (bio)chemical microarray fabrication. The frame is movable to different positions, such as for mounting the substrate to the frame, depositing droplets on the substrate, and applying a bulk liquid to the substrate. The substrate orientation device may be movable to different locations, such as different liquid dispensing devices, for example a printer and a flow cell.

摘要： Methods and apparatus are provided for washing pipette tips, including the inside and outside of the pipette tip. Pipette wash devices comprise a main body comprising a wash chamber, a liquid channel, a gas channel, and a nozzle cavity, and a nozzle for providing a washing mist is positioned in the nozzle cavity and fluidically connected with the liquid channel and the gas channel. Methods of washing a pipette tip include inserting a pipette tip in a wash chamber; spraying a mist on an outside surface of the pipette tip; and blowing pressurized air or inert gas on the outside surface of the pipette tip, thereby washing and drying the pipette. Methods of washing a pipette tip also include passing one or more series of liquid slugs separated by gaseous gaps through the inside of the pipette tip.

摘要： Novel tools and techniques are provided for implementing liquid level detection, particularly, for implementing pressure-based liquid level detection, and, more particularly, for implementing pressure-based liquid level detection that takes into account presence of foam, wet septum seals on a container, and/or pressure changes caused by a partially sealed septum of a container.
