FRITSCH ANALYSETTE 3 PRO - Manual (Page 30)

1 Clamping lid with a nozzle
2 Clamping ring with fast locking clamp
3 Sieve pan (with funnel)
4 Sieve spacer ring with 2 seals
5 Micro-precision sieve
n Turn the rubber pad on the vibratory plate until three caps can be
seen; there are three threaded bore holes under the caps.
n Take off the caps and screw the sieve pan (with funnel) (3) onto the
centre of the vibratory plate using the clamping elements and
knurled screws. The three clamping elements are now lying on the
lower edge of the sieve pan and the vibratory plate.
n Close the hose with a hose clamp.
n Switch on the sieve shaker in "MICRO" operating mode.
n Fasten the first spacer ring onto the sieve pan (3) using the clamping
ring (2).
n Then, fill the sieve pan with the funnel (3) and the spacer ring (4)
with liquid up to the seal ring.
n Fit the first sieve (5) - sieve foil at the bottom - tilted at first so that
the air under the sieve can escape.
n Lower the sieve slowly. The liquid now rises above the sieve foil.
n Place another spacer ring (4) on the sieve and fasten both spacer
rings to one another with a clamping ring (2).
n If several sieves are used in the sieve stack, attach the subsequent
sieves in the same manner.
n Fill every sieve with liquid before fitting the next sieve.
n Fasten the sieve cover (1) on the top spacer ring using a clamping
ring (2).
n Connect a hose (with hose clamps) to the coupling on the sieve
cover, through which water can be fed.
6.4.4 Wet sieving with micro-precision sieves
Remove the lid and pour the sieving stock in suspensions onto the top
sieve. Liquid can be sprayed in through the nozzle in the lid. Keep in
mind, however, that consumption can be considerably reduced by the
time sieving is finished; it is therefore necessary to adjust the quantity of
liquid.
Introducing the liquid (water or alcohols) using a spray bottle has proven
successful. It makes it possible to disperse the sieving stock in a targeted
manner and accelerate sieving progress (=sieving without sieve cover).
When sieving in the top sieve is finished, lower the liquid level to the
height of the sieve foil, close the outlet again and reduce the amplitude
to 0.1 - 0.2 mm. Then remove the sieve cover, spacer ring and the sieve.
