Insertion and clamping the analytical
sieves
The AS 200 control is suitable for analytical sieves of outside
diameter 100 – 203 mm.
Up to 8 analytical sieves plus the collecting bottom can be
clamped in position.
For this purpose various clamping units or clamping covers are
available (see accessories).
If the collecting bottom should stick to the smooth surface of
the sieve support base when removing the sieve set, we
recommend the use of talcum powder.
Shorter threaded rods are available for the sieve clamping unit
for clamping max. 5 analytical sieves plus a collecting bottom
(see accessories).
