* Error limits related to the nominal capacity (= maximum volume) indicated on the instrument, obtained when instrument and
distilled water are equilibrated at ambient temperature (20 °C/68 °F) and with smooth operation.
** Error limit: EL = A + 2CV, according to DIN EN ISO 8655-6 Annex B
(A = accuracy, CV = coefficient of variation, EL = error limit)
The titration volume is displayed in steps of 1 µl at instruments with 10 ml
and 25 ml size and in steps of 2 µl for 50 ml size instruments. For titration
volumes above 20 ml the display will automatically switch to steps of 10 µl.
Material and reagents
The instrument can be used for the following titration media
(maximum concentration 1 mol/l):
Acetic acid
Alcoholic potassium hydroxide
solution
Ammonium iron (II) sulfate solution
Ammonium thiocyanate solution
Barium chloride solution
Bromide bromate solution
Cerium (IV) sulfate solution
EDTA solution
Hydrochloric acid
Hydrochloric acid in Acetone
Iodide Iodate solution*
Iodine solution*
* Use light shield inspection window
When the instrument is properly handled, dispensed liquid will only come into contact with the
following chemically resistant materials: borosilicate glass, Al
platinum-iridium; PP (screw cap).
Limitations of use
Chlorinated and fluorinated hydrocarbons or
chemical combinations which form deposits
may make the piston difficult to move or may
cause jamming.
Compatibility of the instrument for a special
application (e.g., trace material analysis) must
be checked by the user. For additional infor-
mation, please contact the manufacturer.
The instrument is not autoclavable!

Note:
If you need an official certification which confirms the
error limits that are much stricter than those of DIN EN
ISO 8655-3, we recommend a calibration certificate
from an accredited calibration laboratory (e.g., the
DAkkS laboratory at BRAND).
