Abstract
A multi-channel head of a liquid handling apparatus for aspirating and dispensing a metered amount of liquid is configured to attach an array of disposable tips in a pick-up action, in which the multi-channel head is lowered relative to the disposable tips so as to insert each connector into an internal passageway of a corresponding disposable tip by an amount sufficient to bring an upper collar of the disposable tips into contact with an underside of the alignment plate which in turn deforms the elastomeric seal against the tip internal passageway so as to form a sealing contact therewith. An alignment action is thereafter performed in which the alignment plate is moved relative to connectors by an amount sufficient to close any gap between the underside of the alignment plate and the upper surface of the tip collars that arises due to e.g., relaxation of the deformed seals.
