Sieve Shaker AS 200 tap
RETSCH analytical sieve shakers are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring.
The AS 200 tap is particularly used for sieve analysis of certain products such as activated carbon, abrasives, metal powder, spices and diamonds, as specified in the corresponding standards.
Product Advantages
- horizontal, circular movement with taps
- oscillations and taps are independent of power frequency which makes analysis results comparable world wide

- measuring range 20 µm to 25 mm
- suitable for dry sieving
- adjustable plate for sieve stack
- digital timer
- integrated interface
- easy operation
- maintenance-free
- 2-year warranty
- CE-marked with sound enclosure cabinet

Function Principle
In the AS 200 tap, mechanical action is applied to the test sieves in two dimensions. In addition to a horizontal circular motion with 280 oscillations, a vertical tapping motion with 150 taps per minute helps the particles to pass the sieve apertures. This combination of sieving motions simulates hand sieving. The number of oscillations and taps is independent of the power frequency which makes the sieving results of the AS 200 tap comparable world wide.
