Abstract
Pipette system for the volumetric extraction and linear deposition of a suspended material, in particular cells or particles. The pipette system consists of a capillary containing a piston inserted in such a way as to prevent the passage of liquids. Part of the rim forming the orifice of the capillary has a projection. The width of the projection determines the width of the smear regardless of the diameter of the capillary, even when the deposition of the suspension onto the slide or the like is contactless.
