Pipetting device
First Claim
1. A pipetting device having first and second supports, the first support supporting a pipetting head and the second support defining a location for one or more vessels or substrates to or from which fluid is to be pipetted in use;
- and characterised by a pipetting head supported on the first support, comprising a two-dimensional array of pipetting cylinders having pistons for controlling the aspirating or dispensing of liquid from or to one or more of the vessels or substrates, each pipetting cylinder piston being connected to a platen for simultaneous movement of the pistons within the cylinders, and the pipetting head and the second support being relatively movable to one another between an operating and a retracted relationship;
a detachable pipetting tip holder comprising a two-dimensional array of pipetting tips connectable to the pipetting cylinders for aspirating liquid from or dispensing liquid into or onto a corresponding vessel or substrate respectively;
wherein the pipetting head is operative to cause the pistons of the pipetting cylinders to move simultaneously; and
each of the pipetting tips is individually movable in the direction of a corresponding vessel or substrate relative to the pipetting tip holder.

Abstract
A pipetting device has top and bottom supports, the first support supporting a pipetting head and the second support defining a location for one or more vessels or substrates to or from which fluid is to be pipetted in use. The pipetting head has a two-dimensional array of pipetting cylinders having pistons for controlling the aspirating or dispensing of liquid, each pipetting cylinder piston being connected to a platen for simultaneous movement of the pistons within the cylinders. The pipetting head and the second support are relatively movable to one another between an operating and a retracted relationship. A detachable pipetting tip holder has a two-dimensional array of pipetting tips which are connectable to the pipetting cylinders for aspirating liquid from or dispensing liquid into or onto a corresponding vessel. The pipetting head is operative to cause the pistons of the pipetting cylinders to move simultaneously, and each of the pipetting tips is individually movable in the direction of the vessel relative to the pipetting tip holder.
