4. The pipette tip system of claim 1 , wherein the first adjacent base comprises a second top edge, a second bottom edge, and a third short side ( 88 A), and the first adjacent base further comprises:

a third top edge set of interlocking keys ( 86 A, 86 B) positioned adjacent to the second top edge along the third short side ( 88 A);

a third bottom edge set of interlocking keys ( 87 A, 87 B) positioned adjacent to the second bottom edge along the third short side ( 88 A);

wherein the first top edge set of interlocking keys mates with the third top edge set of interlocking keys, and

wherein the first bottom edge set of interlocking keys mates with the third bottom edge set of interlocking keys.

5. The pipette tip system of claim 1 , wherein the first adjacent base comprises a second top edge, a second bottom edge, and a third long side ( 88 B), and the first adjacent base further comprises:

a third top edge set of interlocking keys ( 86 A, 86 B) positioned adjacent to the second top edge along the third long side ( 88 B);

a third bottom edge set of interlocking keys ( 87 A, 87 B) positioned adjacent to the second bottom edge along the third long side ( 88 B);

wherein the first top edge set of interlocking keys mates with the third top edge set of interlocking keys, and

wherein the first bottom edge set of interlocking keys mates with the third bottom edge set of interlocking keys.

6. The pipette tip system of claim 1 , wherein the array of pipette tip receiver openings ( 52 ) is arranged in a N×M array, wherein N is less than M, and wherein the support card comprises:

a short-side card rail edge ( 66 B) on an edge of the support card along the N side of the array; and

a long-side card rail edge ( 66 A) on an edge of the support card along the M side of the array;

wherein the system further comprises a support card lid ( 60 ) comprising:

a long-side lid rail edge ( 65 A) extending from a support card first surface ( 61 ), which is adapted to slidably mate with the long-side card rail edge ( 66 A); and

a short-side lid rail edge ( 65 B) extending from a support card second surface ( 62 ), which is adapted to slidably mate with the short-side card rail edge ( 66 B).

7. The pipette tip system of claim 6 , wherein when the long-side lid rail edge ( 65 A) slidably mates with the long-side card rail edge ( 66 A), the lid ( 60 ) can be positioned to expose fewer than all of the pipette receiver openings ( 52 ) in the array.

8. The pipette tip system of claim 6 , wherein when the short-side lid rail edge ( 65 B) slidably mates with the short-side card rail edge ( 66 B), the lid ( 60 ) can be positioned to expose fewer than all of the pipette receiver openings ( 52 ) in the array.

9. The pipette tip system of claim 1 , wherein the support card comprises an apron ( 51 ) extending away from the top surface ( 56 ).

10. The pipette tip system of claim 1 , wherein the support card is adapted to receive pipette tips ( 10 A, 10 B, 10 C) of different sizes.

11. The pipette tip system of claim 1 , wherein the support card ( 50 A, 50 B) comprises:

a plurality of pipette tips ( 10 A, 10 B, 10 C) disposed of in the array of pipette tip receiver openings ( 52 ), and each in the plurality of pipette tips ( 10 A, 10 B, 10 C) has a distal end ( 15 );

wherein the system further comprises a support card lid ( 60 ) detachably attached to the support card ( 50 A, 50 B) and configured to prevent the distal ends ( 15 ) of the pipette tips ( 10 A, 10 B, 10 C) from contacting one another.
