The Fractionating Aspirator is an impeller type aspirator that utilizes terminal velocity to separate light materials from heavy materials and partitions them into fractions.
It can upgrade seedlots by separating seeds within same size classes into density gradients. Empty and partially filled seeds can sometimes be removed by fractionating aspirators, an efficient device for specific gravity separations.
The unit provides adjustable, four stage, high pressure air aspiration for complete cleaning and separation.
