Abstract

According to an example aspect of the present invention. there is provided a holder for disposable pipette tips, the holder comprising: two pairs of opposing lateral sidewalls, each sidewall comprises an outer surface, an inner surface, an upper edge and a lower edge, and two lateral edges; the sidewalls are joined to each other via their lateral edges; a plate comprising a matrix of openings, connected to the upper edges of the sidewalls; wherein the holder may be locked on top of another holder to form a stack of holders; wherein the locking is configured to be released by applying a force to a locking element from above the stack of holders.

Claims (48)

1 . A holder for laboratory consumables, the holder comprising:

two pairs of opposing lateral sidewalls;

each sidewall comprises an outer surface, an inner surface, an upper edge and a lower edge, and two lateral edges;

the sidewalls are joined to each other via their lateral edges;

a plate comprising a matrix of openings, connected to the upper edges of the sidewalls;

a surface arranged lower than the plate;

at least one release opening located in said surface; and

means for locking the holder on top of another holder to form a stack of holders;

wherein the locking is configured to be released by inserting a release device into the at least one release opening so that a vertically-directed input force is applied to said means for locking from above the stack of holders.

2 . The holder according to claim 1 , wherein:

said surface is parallel with said plate comprising a matrix of openings.

3 . The holder according to claim 1 , wherein the means for locking comprises at least one flexible or deformable tongue.

4 . The holder according to claim 1 , wherein the means for locking comprises a radially deformable hollow pin.

5 . The holder according to claim 1 , wherein the means for locking is detachable from and re-attachable to the holder.

6 . A set of parts comprising at least a first holder and a second holder for disposable pipette tips according to claim 1 .

7 . The set of parts according to claim 6 , wherein the holders are locked to each other, the first holder on top of the second holder, and form a stack.

8 . The set of parts according to claim 6 , wherein each holder comprises the at least one release opening into which a release device can be inserted from above the stack of holders in order to release the locking, the set of parts further comprising a release device configured to be inserted into the at least one release opening or openings of the topmost holder of the stack from above the stack of holders in order to release the locking between the topmost holder and the holder lying immediately below it.

9 . The set of parts according to claim 8 , wherein the release device is in the form of a pin, a bar or a handle, and an end of said release device is configured to be inserted into the at least one release opening of the topmost holder.

10 . The holder according to claim 1 , wherein the locking is configured so that the release device bends at least two tongues of the means for locking to release the locking.

11 . A method of manipulating holders of laboratory consumables, the method comprising:

providing a locked stack of holders; wherein a holder comprises at least one release opening;

releasing the locking between the uppermost holder and the holder lying immediately below it by inserting a release device into the at least one release opening so that a vertically-directed input force is applied to a means for locking in the uppermost holder from above the stack of holders; and

removing the uppermost holder from the stack of holders.

12 . The method according to claim 11 , wherein said vertically-directed input force is applied by a user or by an automated device.

13 . The method according to claim 11 , wherein said providing step comprises providing a locked stack of holders to a platform of an automated device, wherein said force is applied by the automated device, and wherein each holder in the locked stack of holders comprises:

two pairs of opposing lateral sidewalls;

each sidewall comprises an outer surface, an inner surface, an upper edge and a lower edge, and two lateral edges;

the sidewalls are joined to each other via their lateral edges;

a plate comprising a matrix of openings, connected to the upper edges of the sidewalls; and

means for locking it on top of another holder to form a stack of holders.

14 . The method according to claim 13 , wherein the uppermost holder becomes connected to the release device upon said releasing of the locking, and said removing comprises lifting the uppermost holder from the stack together with and as connected to the release device.

15 . A means for locking a first holder of laboratory consumables on top of a second holder of laboratory consumables to form a locked stack of holders, wherein each holder comprises:

two pairs of opposing lateral sidewalls;

each sidewall comprises an outer surface, an inner surface, an upper edge and a lower edge, and two lateral edges;

the sidewalls are joined to each other via their lateral edges; and

a plate comprising a matrix of openings, connected to the upper edges of the sidewalls;

at least one release opening;

wherein

the means for locking is attachable under the first holder, and when attached, said means is encased by the lateral sidewalls and the matrix plate of the first holder;

the means for locking comprises a bendable or deformable part that is configured to engage with the second holder in the locked position of the holders; and

the locking is configured to be released by inserting a release device into the at least one release opening so that a vertically-directed input force is applied to said bendable or deformable part from above the stack of holders.

16 . A holder for laboratory consumables, the holder comprising:

two pairs of opposing lateral sidewalls;

each sidewall comprises an outer surface, an inner surface, an upper edge and a lower edge, and two lateral edges;

the sidewalls are joined to each other via their lateral edges;

a plate comprising a matrix of openings, connected to the upper edges of the sidewalls; and

means for locking the holder on top of another holder to form a stack of holders;

wherein the locking is configured to be released by applying a force to said means for locking from above the stack of holders, wherein the means for locking comprises a radially deformable hollow pin.
