Maintenance And Care Of The Titronic 110 Plus Piston Burette; Storage And Transportation - SCHOTT TITRONIC 110 plus Manual De Instrucciones

48 Maintenance and care of the TITRONIC
Maintenance work to be performed
- Check the piston and the cylinder for visible signs of mechanical damage, such as cracks, fractures and
damage of the surface.
- Check the piston rod for corrosion.
- Check the hoses, screw unions, and seals for signs of visible damage, contamination, and leaks.
- Check the electrical plug contacts for corrosion and mechanical damage (on piston burette and cables).
- Defective parts must be repaired or replaced by new ones. Defect glass parts must always be replaced.
- After each maintenance operation, a test for metrological reliability according to DIN 12 650, part 6, or
ISO DIN 8655, Part 3, has to be carried out.
Periods without operation
− If the interchangeable units used with the TITRONIC
tended period of time, the liquids contained in the system, in particular aggressive solutions, have to be
drained. If the liquid is left in the system, one has to reckon with corrosion and an alteration of these
solutions used over time. Since the state of the art does not offer any plastic hoses which would be ab-
solutely free of diffusion occurrences, this precaution measures apply in particular to the hose-line sec-
tion.
−
Cleaning
- The interchangeable units may be cleaned using a piece of cloth soaked in normal water or a household
cleansing agent containing ethanol. In general, short-term immersion in, or rinsing with, water or ethanol
is not harmful, but this method should only be applied in extreme cases.
- The casing of the lower section of the piston burette may also be cleaned using a piece of cloth and a
household cleansing agent. The lower and rear side have to be dry-cleaned. In no case must water
penetrate into the interior of the lower section.
Reproducibility of results
−
The measurement results or analysis results depend on a variety of factors. Please check the plausibil-
ity of the measurement results or analysis results at regular intervals, and carry out the required reli-
ability tests. In this regard, please adhere to the usual validation procedures.

Storage and transportation

®
If the TITRONIC 110 plus Piston Burette or the interchangeable units have to be stored over some time,
or to be dislocated, the use of the original packing will be the best protection of the devices. However, in
many cases this packing will not be available any more, so that one will have to compose an equivalent
packaging system. Sealing the lower section in a foil is hereby recommended.
The devices should be stored in a room with a temperature between +10 and +40°C, and the (relative)
humidity of the air should not exceed 70 %.
