AS 200 jet: Air Jet Sieving Machine
Brand: Retsch | Category: Scientific & Laboratory Equipment
Air jet sieving machine for fine powders that agglomerate or will not pass a mesh under vibration alone. A rotating slotted nozzle blows a jet of air up through the mesh to disperse the sample while a vacuum draws the undersize away, so each cut is made on a single sieve rather than a stack. It is used where a conventional vibratory shaker cannot disperse the material.

- AS 200 jet pro / AS 200 jet pharma: Air Jet Sieving Machines
Air jet sieving machines that combine sieving and weighing in one instrument, so the sieve does not have to be removed between fractions. The pharma version adds audit trail functionality for regulated laboratories. Both work on the rotating air jet principle for fine powders that will not disperse under vibration.
- AS 450 control: Vibratory Sieve Shaker
The largest vibratory sieve shaker in the Retsch range, using controlled electromagnetic tapping technology to drive sieve stacks of up to 25 kg. It accepts 400 mm and 450 mm sieves and covers a measuring range from 25 µm to 125 mm, which takes in coarse aggregate as well as fine fractions. Amplitude is digitally set and held constant regardless of load.
- AS 200 tap: Tap Sieve Shaker
Tap sieve shaker that mechanises the manual sieving procedure specified in several national standards, superimposing a vertical tapping action on a horizontal circular motion. It is used where a standard calls for tapping rather than vibration, and gives the reproducibility of a machine in place of hand sieving.
