INTENSIVE CLEANING OF BURETTE:
The dispensing cylinder, valve, telescoping filling tube and titrating tube
are filled with reagent. For this reason, always perform a standard
cleaning before dismantling the instrument. In order to avoid confusion
about the components, do not dismantle more than one instrument at a
time. A calibration and any necessary adjustment, must be carried out
after dismantling or replacement of a piston/cylinder assembly.
Note: Use rubbing alcohol on a cloth or cotton to clean the external
body.
Proper storage of digital burette is as important as cleaning and
calibrating the instrument. The digital burette and its all accessories
must be stored in a clean, cool and dry place. The storage temperature
should be ranging from –20 °C to +50 °C (from –4 °F to 122 °F) is advised
with relative humidity between 5% and 95%. Another point to be
remembered is that the instrument should be stored in an upright
position as recommended by the manufacturer.
