Abstract

A support is provided that is useful with a pipette tip holder for pipette tips. The support has a bottom member and a pair of opposed side walls that extend from the bottom member at least a distance (d). The bottom member and side walls form a cavity. Each side wall defines a slot. The slots are in a facing relationship and extend along a support plane that is parallel to and spaced from the bottom member the distance (d). The slot ends are open on one side so as to receive the pipette tip holder when slidingly inserted into the slots. The side walls preferably include an aligning member adjacent to the open slot end so that the pipette tip holder is aligned in the slots when slid in. Thus, the support supports the pipette tips and pipette tip holder during the pipette tip removal process and resists inadvertent dislodging and lifting of the tips and holder as the tips are removed.

Claims

1. A support, useful with a pipette tip holder and pipette tips therein, comprising:

a bottom member; and

a pair of opposed side walls attached to the bottom member and extending therefrom at least a distance (d), the bottom member and side walls forming a cavity therebetween, each side wall defining a slot therein, the slots being in a facing relationship and extending between a first end and a second end along a support plane, the support plane being parallel to and spaced from the bottom member the distance (d), the first slot ends being open to receive a pipette tip holder when slidingly inserted therein, the second slot ends being closed to stop further sliding of the pipette tip holder therein.

2. The support of claim 1 wherein the side walls include an aligning member adjacent to the first slot ends and being of a construction sufficient to align the pipette tip holder in both slots when slidingly inserted therein.

3. The support of claim 1 further comprising at least one support member disposed within the cavity and having an upper surface lying in the support plane.

4. The support of claim 2 where the aligning member is a recess portion.

5. The support of claim 1 where the side walls are solid.

6. The support of claim 1 where the side walls are partially open.

7. The support of claim 1 where the slots are sufficiently deep to prevent the pipette tip holder from being lifted up as tips are removed.

8. The support of claim 1 where the second slot ends are closed by a solid member adjacent to the second ends.

9. The support of claim 1 where the second slot ends are closed by a bar extending between the slots in the support plane.

10. The support of claim 1 where the second slot ends are closed by a block.

11. The support of claim 1 where distance (d) is such that when a pipette tip holder is inserted into the slots, tips in the pipette tip holder do not touch the bottom.

12. The support of claim 1 where the side walls do not extend above the tops of the tips when a pipette tip holder with at least one pipette tip is inserted in the slots.

13. The support of claim 3 where at least one support member has sufficient strength to prevent the pipette tip holder from being bent as tips are removed from the pipette tip holder.

14. The support of claim 13 including at least one support member in between each row of pipette tips in a pipette tip holder.
