Pipette wash
First Claim
1. A method of washing an array of pipette tips comprising:
- providing a dispensing jet system including the array of pipette tips;
lowering the array of pipette tips into a wash basin comprising an array of flush ports, the wash basin positioned on a shiftable wash valve plate comprising an array of valves, the shiftable wash valve plate enabled to work with a vacuum source to control vacuum timing;
generating a vacuum and shifting the wash valve plate such that the residual biological material in the array of pipette tips is evacuated through the array of flush ports and the array of valves; and
running a wash cycle comprising;
raising the array of pipette tips from the wash basin;
filling the wash basin with a primary wash fluid;
lowering the array of pipette tips into the wash basin;
running a pipette tip cleansing cycle using dispensing pipette piston cycles of the dispensing jet system to aspirate and dispense the wash fluid in the pipette tips; and
generating a vacuum such that the primary wash fluid in the array of pipette tips and the wash basin is evacuated through the array of flush ports; and
positioning a vacuum conduit above the wash basin, the vacuum conduit coupled to a vacuum source to remove vapors from above the wash basin during the wash cycle and/or after the wash cycle.

Abstract
A method of washing an array of pipette tips (94) with residual biological material includes lowering the array of pipette tips (94) into a wash basin (20) that includes an array of flush ports (22). A vacuum is generated such that the residual biological material in the array of pipette tips (94) is evacuated through the array of flush ports (22). A wash cycle is performed that includes raising the array of pipette tips (94) from the wash basin (20), filling the wash basin (20) with a primary wash fluid, lowering the array of pipette tips (94) into the wash basin (20), miming a pipette tip cleansing cycle, and generating a vacuum such that the primary wash fluid in the array of pipette tips (94) and the wash basin (20) is evacuated through the array of flush ports (22).

14. A system for washing an array of pipette tips comprising:
-
a plurality of wash jets; a wash basin comprising an array of flush ports for receiving the array of pipette tips, the wash basin positioned on a wash valve plate comprising an array of valves, the wash valve plate being shiftable and configured and arranged to work with a vacuum source to control vacuum timing; a primary pump for filling the wash basin with a primary wash fluid; a dispensing jet system including the array of pipette tips, the dispensing jet system configured to operate a pipette tip cleansing cycle using dispensing pipette piston cycles of the dispensing jet system to aspirate and dispense the wash fluid in the pipette tips; and a vacuum generator for generating a vacuum such that the primary wash fluid and any residual biological material in the array of pipette tips and the wash basin is evacuated through the array of flush ports and the array of valves; and a vacuum conduit positioned above the wash basin, the vacuum conduit coupled to a vacuum source and configured and arranged to remove vapors from above the wash basin. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
