NOTE
Screw the lid only hand-tight as overtightening may break the glass cylinders. Test the tightness of
the system with water prior to the installation onto the heating plate.
7 .5 Glass components
To prolong the lifetime of the glass components rinse them regularly with water and a commercial
cleaning agent (e.g. mild soap solution).
NOTE
It is recommended to clean all glass components manually. Use an alkaline cleaner to remove dirt,
e.g. algae adhering to the condenser coil.
When a thin copper wire is introduced into the condenser coil, the risk of dirt adhering to the
condenser coil is reduced.
Remove all grease from the joints. After cleaning and completely drying each glassware component,
visually inspect them for glass splinters or tears. As these components are under vacuum during
operation they are subject to strain.
Regularly check the glassware components for damage and use only glassware in perfect condition,
i.e. glassware without cracks or stars.
Chipped sample tube borders may cause leaking. Check the quality of the sample tubes regularly,
especially when a dishwasher is used.
7 .6 PE frits (optional)
To remove the optional PE frits from the tube adapter, push
a thin object from the top through the hole.
