Abstract

"IMPROVED AGITATOR DEVICE", of the type used in analysis laboratories for the measurement of times of formation of coagulation in studies of blood haemostasia, which incorporates within it a magnetised agitator bar (3) in a basically cylindrical form, characterised essentially because the cylindrical magnetised bar (3) is actioned by a magnet (4) which is located at one side of the interior of a support (10) on which the receptacle (2) is placed, the said magnet (4) presenting a vertical orientation of the magnetic poles, which means that, through the magnetic field, the magnetised bar (3) is positioned vertically, comprising a motor (5) on the shaft of which (6) the support (10) is fixed, which incorporates laterally within it the magnet (4), presenting a motion which causes a circular movement of the bar (3) of the receptacle (2).
