Pipette tip trays
View Patent ↗Provided are pipette tip trays for use in biotechnology applications. In certain embodiments, provided are pipette tip trays having one or more of the following features: (i) lacking an external hinge between the lid and the rack, and (ii) having snap plate fasteners configured to releasably secure a snap plate to a base.
1. A pipette tip tray, comprising:
a top comprising an array of bores, each bore configured to receive a partially-inserted pipette tip;
a base with sides, wherein a side comprises a step around the base perimeter and at least one slot in the step; and
a lid comprising at least one molded tab extending from the lid, wherein:
the at least one tab is inserted in the at least one slot;
the tab and slot form an internal hinge,
the tab is flexible,
the tab comprises the same material as the lid;
the tab is in flexible association with the lid at a junction between the tab and the bottom edge of the lid, and
the hinge is configured for the lid to pivot around the junction.
2. The pipette tip tray of claim 1 , wherein the side comprises two slots and the lid comprises two tabs.
3. The pipette tip tray of claim 1 , wherein a side including the step and the slot in the step are located on a short side of the tray.
4. The pipette tip tray of claim 1 , wherein a side including the step and the slot in the step are located on a long side of the tray.
5. The pipette tip tray of claim 1 , wherein the tab associates with the slot in a slidable fit.
6. The pipette tip tray of claim 1 , wherein the tab is engaged in the slot and the lid is in an open position at an angle sufficient to allow access to the pipette tips.
7. The pipette tip tray of claim 1 , wherein the tab is engaged in the slot and the lid is in a partially open position at an angle sufficient to allow access to the pipette tips.
8. The pipette tip tray of claim 1 , wherein the tab extends below the plane of the step around base perimeter when engaged.
9. The pipette tip tray of claim 1 , wherein the tab is configured for reversible engagement with the slot.
10. The pipette tip tray of claim 1 , wherein the lid and the tab are configured for the lid to pivot with respect to the tray about the junction between the tab and the lid when the tab is engaged in the slot.
