Spill-resistant microtitre trays and method of making
First Claim
Patent Images
1. A method of manufacturing a spill-resistant microtitre tray structure, comprising:
- providing a modified microtitre tray which includes regularly spaced apart wells, each well having an open top and an open bottom located at opposite ends of the well;
providing an unmodified microtitre tray which includes wells having a same spacing as those of the modified microtitre tray, each well having an open top and a closed bottom located at opposite ends of the respective well, a shape of the wells belonging to the unmodified tray being identical to a shape of the wells belonging to the modified tray except for the open bottoms of the wells on the modified tray; and
inserting at least a plurality of wells of the modified microtitre tray into a plurality of wells of the unmodified microtitre tray, to thereby form a stacked arrangement in which the plurality of wells of the modified microtitre tray serve as spill-resistant lids for the wells of the unmodified microtitre tray into which the plurality of wells are inserted.

Abstract
Microtitre trays and their spill-resistant open lids prevent cross contamination of samples and also accommodate fragile and flexible probes of automated biological sample analysis systems. The open-lids can be in the form of sleeves located on the top sides of each well of microtitre trays. In one version, one microtitre tray with its bottom sections severed is stacked on top of another microtitre tray to provide the open-lids. A cutting tool is also provided to sever the bottom sections of each well from microtitre trays. The cutting tool includes a lever, a blade and a clamping device.

6. A spill-resistant microtitre tray structure, comprising:
-
a modified microtitre tray including regularly spaced apart wells, each well having an open top and an open bottom located at opposite ends of the well; and
an unmodified microtitre tray which includes wells having a same spacing as those of the modified microtitre tray, each well having an open top and a closed bottom located at opposite ends of the well, wherein at least a plurality of the wells of the modified microtitre tray are inserted into a plurality of wells of the unmodified microtitre tray to thereby form a stacked arrangement in which the plurality of wells of the modified microtitre tray serve as spill-resistant lids for the plurality of wells of the unmodified microtitre tray, and wherein a shape of the wells belonging to the unmodified tray is identical to a shape of the wells belonging to the modified tray except for the open bottoms of the wells on the modified tray. - View Dependent Claims (7, 8, 9, 10, 11)
to thereby form a friction fit between the modified microtitre tray and the unmodified microtitre tray. -
9. The structure according to claim 6 wherein the stacked arrangement includes a contact region where the unmodified and modified trays touch each other, and
wherein the contact region includes an adhesive. -
10. The structure according to claim 6, wherein each of the modified and unmodified microtitre trays includes a two dimensional array of wells.
-
11. The spill-resistant microtitre tray structure according to claim 6, wherein the modified tray and the unmodified tray are identical in shape, except for the open bottoms of the wells on the modified tray.
