ABSTRACT:
An analytical device incorporating a system for suspending particles includes a conveying device for positioning a pipetting needle at a distance from the central longitudinal axis of the reaction vessel. Particles are suspended by delivering amounts of liquid reagent to two different positions at a predetermined distance from the central longitudinal axis of a reaction vessel, such delivery generates a flow in the reaction vessel which suspends particles exclusively by injection of liquid, thus avoiding the need for subsequent shaking.
