In a horizontal sieve shaker (e.g. Retsch AS 400 control) the sieves move in horizontal circles in one plane. Horizontal sieve shakers are preferably used for needle-shaped, flat, long or fibrous samples, as their horizontal orientation means that only a few disorientated particles enter the mesh and the sieve is not blocked so quickly. The AS
