ABSTRACT:
An arrangement for determining the blood cell sedimentation rate, comprising a pipette having at the upper end thereof a levelling device; a tube and a plunger sealingly engaging the outside wall of the pipette and having a diameter generally the same as the inside diameter (d) of the tube. The plunger is inserted in the tube at a distance from the lower end of the pipette such that when the plunger is inserted in the tube until such lower end of the pipette abuts the bottom end of the tube, it displaces blood into the pipette capable of filling the pipette without overflowing from the ensemble formed by the pipette plus the levelling device.
