MULTI-CHANNEL PIPETTE TOOLS
A tool which may be picked up by a dispense head and coupled to a pipette tip coupler. The pipette tip coupler can manipulate gripping arms of the tool using the tip ejection members. A microplate can be transported by this took, the tool parked at a parking location, and the pipette tip coupler used for other uses, such as aspirating or dispensing liquid when pipette tip is coupled onto the pipette tip coupler.
1 . A tool used to transport a multi well plate, comprising:
a multi well plate transport tool having two gripping arms spaced to allow retractable gripping of a multiwell plate;
a bridge having a first side end with a first gripping arm secured thereto, and a second side end with a second gripping arm secured thereto;
a plurality of wells on said bridge, said wells dimensioned to allow a pipette tip coupler to be received with said well;
at least two latches, each latch positioned proximate to a top opening of one of said plurality of wells on said bridge, each of said latches mounted such that each latch can be moved back from a surface of said pipette tip coupler and into a latch position in which said latch mates with a groove on said pipette tip coupler; and
a release structure on said bridge, said release structure including an angled surface which may be moved vertically against another surface, wherein such movement against said angled surface creating a pressure on said bridge to cause said at least two latches to unlatch from receiving grooves on said pipette tip couplers.
2 . The tool of claim 1 , wherein said latches are spring loaded.
3 . The tool of claim 1 , wherein said groove on the pipette tip coupler is an annular notch.
4 . The tool of claim 1 , wherein said pipette tip coupler is configured to couple with an 8 channel pipette head.
5 . The tool of claim 4 , wherein said pipette tip coupler is configured to engage 4 pipette tips on said 8 channel pipette head.
