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.
