Abstract
A magnetic stirrer (1) has a housing (2) for accommodating a drive (3) and a holder or mounting plate (5) for a stirred vessel and a stirring magnet. A plurality of mounting feet (6) are provided for mounting the magnetic stirrer (1) on the base, which mounting feet are mounted in a movable or flexible manner and are connected to a weight measuring device or sensors belonging to a weight measuring device, with the result that the weight of the stirred material or a change in weight can be determined at any time without complicated additional weighing operations.
Claims9
Magnetic stirrer comprising a weighing device for measuring a weight and a housing in which is arranged an electrical stirring drive including a rotating magnet or coils, wherein a holder or mounting plate is provided for a vessel for holding material to be stirred and a stirring magnet, the weighing device comprises deformable spring levers, each having first and second ends, the first ends being mounted to a bottom side of the housing so that the spring levers are cantilevered, and several external mounting feet are provided on the bottom side of the housing, the mounting feet are mounted on the second ends of the spring levers so that, in operation, the mounting feet are movable upwards relative to the housing against a restoring force generated by the spring levers whereby the mounting feet deform said spring levers, and a deformation of the spring levers is indicative of the weight to be measured, the housing comprises one or more recesses or openings arranged at the bottom side of the housing, and the mounting feet are at least in part moveable into the recesses or openings by application of the weight to be measured.
