Pipette tip support card bundles

An interleaved support card bundle comprising,

• a first support card comprising:
• a first top surface containing a first plurality of pipette tip support holes in a first layout;
• a plurality of receiver slots on an underside of the first top surface, each receiver slot having a receiver slot wall and a receiver slot axis extending orthogonally away from the first top surface;
• and
• a first plurality of pipette tips seated in the first plurality of pipette tip support holes, each of the first plurality of pipette tips having a distal end;
• a first apron connected to the first support card and extending from the first top surface;
• a second support card comprising:
• a second top surface parallel to the first top surface, and containing a second plurality of pipette tip support holes in a layout different than the first layout, each in the second plurality of pipette tip support holes defines a pipette tip support hole axis that is aligned with a corresponding receiver slot axis of the plurality of receiver slots;
• and
• a second plurality of pipette tips seated in the second plurality of pipette tip support holes, each of the second plurality of pipette tips having a distal end;
• a second apron connected to the second support card and extending from the second top surface;
• wherein:
• the first apron is detachably connected to the second apron such that the first and second support cards are structurally connected as a single bundle;
• the first plurality of pipette tips extends towards the second top surface and the second plurality of pipette tips extends towards the first top surface, and is interleaved with the first plurality of pipette tips;
• and
• the receiver slot walls of the plurality of receiver slots are sized and shaped to encircle the distal ends of the second plurality of pipette tips, restrict movement of the second plurality of pipette tips, and prevent the second plurality of pipette tips from contacting the first plurality of pipette tips.
