<p>A mechanism for generating an orbital motion for mixing, particularly for shaking, a fluidic sample (38) accommodated by a sample holder (14, 40), wherein the mechanism comprises a stationary mounted or lockable first cogwheel (2) having a first through hole (30) and a plurality of first cogs (80) arranged along an outer circumference of the first cogwheel (2), a movably mounted second cogwheel (4) having a second through hole (32) and a plurality of second cogs (82) arranged along an outer circumference of the second cogwheel (4), a drive shaft (3) having a concentric first section (34) and an eccentric second section (36), wherein the first section (34) is guided through the first through hole (30) and the second section (36) is guided through the second through hole (32), and a coupling body (5) having a plurality of third cogs (84) arranged along an inner circumference of the coupling body (5), wherein the coupling body (5) is mounted with the first cogwheel (2) and with the second cogwheel (4) to engage part of the first cogs (80) and part of the second cogs (82) by part of the third cogs (84) to thereby generate the orbital motion of the second cogwheel (4) and a sample holder (14, 40) to be mounted so as to follow a motion of the second cogwheel (4) upon rotating the first section (34) of the drive shaft (3).</p> |
