The measuring liquid in the supply unit only comes in contact with mate-
rials that are chemically resistant to a large extent. Certain organic liquids
or saturated inorganic salt solutions can be used temporarily without
damaging the instrument.
Please note that the measuring liquid comes into contact with stainless
steel, glass, PTFE, Viton (FPM or FKM) and silicon hoses.
When measuring samples which are incompatible with water, a suitable
liquid with a high boiling point can be selected from the following list:
n
Monovalent, bivalent or trivalent alcohols e.g. isopropanol
n
Benzines (e.g. white spirit),
n
Mineral and organic oils (e.g. petroleum and soy bean oil, nut oil,
olive oil, Miglyol)
n
Saturated solutions of inorganic salts
Samples, which are available in oil (e.g. oils like machine oil), do not
always need to be measured in oil. They can often be measured in white
spirit.
DANGER!
Before using other measuring liquids, consult Fritsch
Gmbh in advance or call up the list of suitable chemi-
cals on our homepage www.fritsch-sizing.de under the
corresponding wet dispersion unit.
We advise against the use of harmful, explosive or flam-
mable liquids.
The above list just states the chemical compatibility of
the device with the liquids that can be used.
The measuring unit and dispersion units are not
designed to be explosion-protected.
DANGER!
The following must not be used:
Ketones (e.g. acetone, propanone, butanone, cyclohex-
anone),
Ether, chlorofluorocarbons,
Amines, freone 21-32, methanol, aniline, benzol
Chlorinated hydrocarbons like acetic acid and its deriva-
tives, undiluted acids and bases.
DANGER!
When using harmful liquids be sure to observe the valid
safety regulations (MAC values). Where necessary, the
measuring unit and dispersion units must be set up in a
ventilated safety area.
