Safety Instructions; Functions And Limitations Of Use - BRAND Titrette Mode D'emploi

Safety Instructions

This instrument may sometimes be used with hazardous materials, operations, and equipment. It is beyond
the scope of this manual to address all of the potential safety risks associated with its use in such applica-
tions. It is the responsibility of the user of this instrument to consult and establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
Please read the following carefully!
!
1. Every user must read and understand this
operating manual before operation.
2. Follow general instructions for hazard preven-
tion and safety instructions; e.g., wear protec-
tive clothing, eye protection and gloves.
3. Never use the instrument in an atmosphere
with danger of explosion.
4. Use the instrument only for titrating liquids,
with strict regard to the defined limitations of
use and operating limitations. Observe operat-
ing exclusions (see page 37)!
5. Observe all safety precautions provided by
reagent manufacturers. If in doubt, contact the
manufacturer or supplier.
6. An instrument mounted on a reagent bottle
should not be carried by the housing.
7. Never turn handwheels when the screw cap is
screwed on.

Functions and Limitations of Use

The bottle-top burette Titrette
non-aqueous titration media (e.g., alcoholic KOH) up to a max. concentration of 1 mol/l (see page 37 for
recommended application range). It comes with a certificate of conformity according to the metrological
requirements of DIN EN ISO 8655-3. Even tight Class A tolerances for glass burettes can be achieved by
using a high-precision measuring system.
When the instrument is properly handled, dispensed liquid will only come into contact with the follow-
ing chemically resistant materials: borosilicate glass, Al
(screw cap). The instrument possesses a recirculation valve as the factory default.
Limitations of Use
This instrument is designed for titrating liquids,
observing the following physical limits:
– +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
– altitude: max. 3000 m above sea-level
– relative air humidity: 20% to 90%

8. Never remove the titrating tube while the glass
cylinder is filled.
9. Never use force on the instrument.
10. Use only original manufacturer's accessories
and spare parts. Do not attempt to make any
technical alterations. Do not dismantle the
instrument any further than is described in the
operating manual!
11. If there is a sign of a potential malfunction
(e.g., piston difficult to move, sticking valves
or leakage), immediately stop titrating. Consult
the 'Troubleshooting' section of this manual
(see page 64), and contact the manufacturer if
needed.
12. The included 1.5 V micro-batteries are not
rechargeable! Dispose of batteries only when
completely discharged, and according to ap-
plicable regulations.

Operating Limitations
Chlorinated and fluorinated hydrocarbons or chemi-
cal combinations which form deposits may make
the piston difficult to move or may cause jamming.
Compatibility of the instrument for this special
application (e.g., trace material analysis) must be
checked by the user or contact the manufacturer.
