FRITSCH ANALYSETTE 3 PRO - Manual (Page 40)

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).
7.5.1.2 Parameters
Grinding duration 10 ... 30 min (average)
Amplitude 1 ... 2 mm (max.)
Feed quantity Max. 10 ml (particle feed size ≤ 5
mm)
7.5.1.3 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.
CAUTION!
When handling liquid nitrogen, the Guidelines for Laborato-
ries, BGR 120, in particular Chapter 5.4.6, must be observed
as well as the other relevant guidelines and codes of prac-
tice.
Suitable protective clothing, particularly safety goggles and
heat-resistant gloves must be worn. Only the smallest pos-
sible amounts should be handled. Make sure that the labo-
ratory is adequately ventilated.
