FRITSCH PULVERISETTE 0 - Manual (Page 23)

The amplitude is set manually with the Plus and Minus key on the con-
trol panel and viewed on the lid. (See Ä Chapter 6.3.1 ‘Displaying the
amplitude’ on page 25)
NOTICE!
Do not allow the grinding balls to jump too high. This can
cause damage to the lid!
Start grinding at low a amplitude and increase it slowly - do
not select an amplitude that is too high! (≤ 2 mm)
There is a risk of the grinding ball destroying the lid. The grinding stock
can be added to the mortar bowl either dry or in suspension.
CAUTION!
Do not allow any liquids to flow into the device.
To reduce the grinding noise, we recommend using a sound
absorption hood (order no. 00.0130.17).
6.1.3 Grinding with liquid nitrogen
CAUTION!
Only use grinding vessels and grinding balls made of stain-
less steel, tungsten carbide or zirconium oxide for grinding
with liquid nitrogen.
The device for grinding in liquid nitrogen (no. 00.2000.00) should be
used to embrittle the grinding stock in liquid nitrogen. In this thermally-
insulated cryo-box, the grinding vessel and the grinding ball can be
cooled down considerably, and only small amounts of liquid nitrogen
must be refilled during grinding.
