BrandTech Scientific Titrette - Manual (Page 37)

English
37
This instrument is designed for titrating liquids,
observing the following physical limits:
– use temperature from +15 °C to +40 °C (59 °F
to 104 °F) of instrument and reagent
– vapor pressure up to 500 mbar
– viscosity up to 500 mm
2 /s
– altitude: max. 3000 m above sea-level
– relative air humidity: 20% to 90%
Limitations of Use
Operating Limitations
Chlorinated and fluorinated hydrocarbons or chemi-
cal combinations which form deposits may make
the piston difficult to move or may cause jamming.
When working with crystallizing solutions follow
cleaning instructions (see pages 54 - 57).
Compatibility of the instrument for this special
application (e.g., trace material analysis) must be
checked by the user or contact the manufacturer.
Functions and Limitations of Use
2 micro-batteries, 1.5 V (AAA/UM4/LR03),
non-rechargeable.
Operating Exclusions
Battery Specifications
Never use this instrument for
– liquids attacking borosilicate glass, Al

, ETFE,
PFA, FEP, PTFE or platinum-iridium (e.g.,
hydrofluoric acid)
– suspensions (e.g., of charcoal) as solid particles
may clog or damage the instrument
– concentrated acids and bases as well as non-
polar solvents which effect swelling of plastics
(e.g., Toluene, Benzene)
– Carbon disulfide, as this media is highly
flammable
– The instrument must not be autoclaved!
– The instrument should not be used in an aggres-
sive atmosphere (e.g., HCl fumes).
Store the instrument and accessories only in
cleaned condition in a dry place.
Storage temperature: from -20 °C to +50 °C
(-4 °F to 122°F), relative air humidity: 5% to 95%.
Storage Conditions
The instrument can be used for the following titration media (max. conc. 1 mol/l):
Recommended Application Range
* Use light shield inspection windows (see page 44).
The above recommendations reflect testing completed prior to publication (Status as of 0514/4). Always follow instructions in the operating
manual of the instrument as well as the reagent manufacturer‘s specifications. Should you require information on chemicals not listed, please
