Abstract

There is provided a plate-like member for pipette tips including a pipette tip insertion hole disposed on a first plane, one or a plurality of communicating holes that is disposed on a second plane as a back face of the first plane and that communicates with the pipette tip insertion hole, and one or a plurality of flow passages through which a liquid discharged from a pipette tip inserted into the pipette tip insertion hole flows from the second plane side to the first plane side.

Claims

1. A plate-like member for pipette tips comprising:

a pipette tip insertion hole disposed on a first plane;

one or a plurality of communicating holes that is disposed on a second plane as a back face of the first plane and that communicates with the pipette tip insertion hole; and

one or a plurality of flow passages through which a liquid discharged from a pipette tip inserted into the pipette tip insertion hole flows from the second plane side to the first plane side.

2. The plate-like member for pipette tips according to claim 1, wherein the pipette tip insertion hole extends through the communicating holes to the second plane side.

3. The plate-like member for pipette tips according to claim 1, wherein the pipette tip insertion hole is disposed in a center in a planar view.

4. The plate-like member for pipette tips according to claim 1, wherein the flow passages are through holes.

5. The plate-like member for pipette tips according to claim 1, wherein an edge is notched in a spreading direction of the plate-like member for pipette tips with a shape of a polygon, a circle or a combination of a polygon and a circle.

6. The plate-like member for pipette tips according to claim 1, wherein the liquid contains at least one selected from cells, proteins, polysaccharides, alcohols, surfactants and synthetic polymers.

7. The plate-like member for pipette tips according to claim 6, wherein the liquid is a biological sample.

8. A pipette tip including the plate-like member for pipette tips according to claim 1.

9. The pipette tip according to claim 8, wherein an inner diameter of the pipette tip insertion hole is formed with a size that allows a distal end of the pipette tip to project from the communicating hole in a state where the pipette tip is inserted.

10. The pipette tip according to claim 8, wherein the plate-like member for pipette tips and the pipette tip are integrally molded.

11. A liquid agitation kit comprising:

the plate-like member for pipette tips according to claim 1; and

a container that contains a liquid discharged from the pipette tip.

12. The liquid agitation kit according to claim 11, wherein the plate-like member for pipette tips has a cross section similar to a cross section of a space where the liquid is contained in the container.

13. A liquid agitation apparatus comprising:

the plate-like member for pipette tips according to claim 1;

a pipette tip that is inserted into the pipette tip insertion hole;

a container that contains a liquid discharged from the pipette tip; and

a pipette controller that controls discharging of the liquid from the pipette tip.

14. The liquid agitation apparatus according to claim 13, further comprising a drive mechanism that changes a relative position in a vertical direction between the pipette tip and the container.
