Exchanging
the
Xenon lamp
The analyzer
automatically and continually
measures
the
intensity
of the Xenon lamp
to
ensure optimal
detection of the fluorescent
signals
during
real time
PCR. 1f the
lamp intensity falis
below the minimum required
intensity,
a
warning is issued
by the
software that the Xenon
lamp must be exchanged.
The Xenon lamp
is available
as a
spare
part from Roche. Please
contact your local
Roche
representative
for details.
Safety
information
Only use the Xenon lamp
available
directly from Roche.
WARNING
Never exchange the Xenon
lamp without turning
the
analyzer power switch off and
disconnecting the power cable.
Non-compliance
poses the danger of
electric shock
and
damage
to
the eyes by the bright
light of the
lamp.
Before
exchanging the Xenon lamp,
make sure
you have waited an appropriate
period
of time
(approximately
20 minutes) after
you shut
down
the analyzer to
allow
the
lamp
to cool. Directly
after completion of a run, the
lamp
is hot
enough to cause an
immediate
burn.
In its
cold state
the lamp
has
a
high internal pressure.
During operation,
the internal
pressure is
higher than in the cold state.
The lamp
is
extremely unlikely
to
explode but
the possibility cannot
be entirely ruled out. Therefore,
when handling the Xenon
lamp
always use the safety
cover supplied. When installing
the lamp,
remove the safety
cover
and always take the following
precautions: wear
goggles and
gloves and protect your
neck.
Take the same precautions
when removing
the lamp.
Do not
get finger marks, grease, paint,
or similar
materials on the
bulb. Before using
the lamp,
remove any such marks with
isopropanol,
ethanol, or any
other
suitable
agent that leaves
no residues on the bulb.
The Xenon lamp does not contain
any
polluting
material.
The used lamp should be
stored
in its safety cover before disposal.
Where
possible, the lamp
should be disposed
of by a specialist
waste management
company.
1f this is not possible,
put on protective
clothing, wrap the
lamp completely in
leather or
thick cloth, smash the lamp,
including
the discharge tube, with
a suitable implement and
dispose of the pieces.
