Abstract

An apparatus for shaking a plurality of vessels, for example in an incubator, has at least one rotatable support 10 (101,102) defining a plurality of support locations for vessels 50 at predefined positions 12 around an upright axis and the support or supports 10 are rotatable around the upright axis to move the vessels between a number of positions about the axis for insertion and removal of the vessels onto and from the support(s) respectively. A drive transmission system 38,381 (39,391) connects the support to a drive motor 382 (392), whereby the support can be rotated to a desired position for loading or unloading of a vessel to or from a respective support location 12. A drive mechanism 33, 36 (37). 35 is operable to move each support location eccentrically about an axis independently of the rotation of the support about the upright axis, so that vessels disposed on the support can be shaken. The drive mechanism includes an elongate shaft 33 and the drive transmission system includes a hollow shaft 38 (39) disposed around the elongate shaft of the drive mechanism.

Claims

1. An apparatus for shaking a plurality of vessels, the apparatus including:

a rotatable support defining a plurality of support locations for vessels at predefined positions around an upright axis and being rotatable around the upright axis to move the vessels between a number of positions about the axis;

a drive transmission system for connecting the support to a drive motor, whereby the support can be rotated to a desired position for loading or unloading of a vessel to or from a respective support location; and

a drive mechanism operable to move each support location eccentrically about an axis independently of the rotation of the support about the upright axis, whereby vessels disposed on the support can be shaken, characterised in that

the drive mechanism includes an elongate shaft and the drive transmission system includes a hollow shaft disposed around the elongate shaft of the drive mechanism.

2. An apparatus according to claim 1, wherein the elongate shaft is integrally formed with or carries a counterbalance.

3. An apparatus according to claim 1, wherein the elongate shaft is supported in bearings at each end.

4. An apparatus according to claim 3, including a plurality of rotatable supports disposed one above the other and wherein the top and bottom supports are connected for movement around the shaft through eccentric bearings.

5. An apparatus according to claim 1, wherein the or each support is configured to receive vessels in two rings substantially coaxial with the elongate shaft, one within the other.

6. An apparatus according to claim 5, wherein the inner and outer rings are independently rotatable relative to one another.

7. An apparatus according to claim 6, wherein the drive transmission system includes a hollow shaft in driving connection with the inner support ring or rings and a separate, co-axially disposed hollow shaft in driving connection with the outer support ring or rings.

8. An apparatus according to claim 1, including a linkage to prevent the supports precessing around the elongate shaft during its rotation to shake the vessels.

9. An incubator including an apparatus according to claim 1.

10. A cell culture system including an incubator according to claim 8.
