An orbital shaking attachment can be fitted or removed
from a magnetic stirrer thereby giving the stirrer the extra
function of orbital shaking in addition to its primary function
of magnetic stirring. The principal of he invention could also
be used to make a dedicated orbital shaker for other
applications such as in an over, incubator or liquid filled
tank. The orbital shaking attachment includes a top-plate/platform
with a circular magnet attached centrally to its
underside and a base-plate with a central circular hole. The
two plates are separated by ball bearings which are able to
roll around orbitally in bearing cups on both plates. When
operated the base-plate is static and the top-plate/platform
moves orbitally. The device is constructed mainly from
non-ferrous material except for the circular magnet and ball
bearings.
