Actions in the case of a broken cell

WARNING
Cells can contain dangerous substances. If the contents are released,
follow the safety instructions of the package insert. If necessary, take
corresponding protective measures (protective goggles, protective
gloves etc.).
CAUTION
Do not turn the photometer upside down to remove the liquid!
When doing so, the liquid could come into contact with electronic com-
ponents and damage the photometer.
The photometer has a drain device through which the contents of a broken
cell can drain off without causing any damage.
After recommissioning, carry out the photometer monitoring for
all measurements.
If, after recommissioning, an error occurs during the wavelength calibration,
the detector lens is probably smudged. In this case, clean the lens as
1 Switch off the photometer and dis-
connect it from the power supply.
2 Let the liquid drain off into a suit-
able container and dispose of it
properly according to the instruc-
tions of the reagent package.
3 Carefully remove all broken glass,
e.g. with tweezers.
4 Carefully clean the cell shaft using
a moist, lint-free cloth. If there are
persistent coatings, use isopropa-
nol for a short time. Especially
clean the bottom parts of the lat-
eral surfaces of the rectangular
cell shaft where the light barriers
for the automatic cell recognition
are located.
5 Let the cell shaft dry.
