WARNING
Risk of injury from flammable and irritating auxiliary
substances
Isopropanol and acetone are highly volatile and
highly flammable substances. They cause serious eye
irritation. Repeated exposure may lead to skin dry-
ness or cracking. Vapors may cause drowsiness and
dizziness.
ð Keep isopropanol and acetone away from heat,
sparks, open flames and hot surfaces. Do not
smoke.
ð Avoid contact with eyes and skin.
ð Wear safety gloves.
ð Do not inhale vapors.
ð Observe the safety data sheets.
Use of isopropanol
With prolonged cleaning with isopropanol, an elec-
trostatic charge may build up on the quartz-block
end-face. The dust attracted in this way can consid-
erably dirty the quartz-block end-face.
ð Use acetone as a detergent in the event of an
electrostatic charge on the quartz-block end-
face and for very persistent soiling.
Use of acetone
Acetone may cause streaks on the quartz-block end-
face.
Streaks may also indicate an insufficient quality of
the cleaning chemicals isopropanol and acetone.
ð Use isopropanol to remove the streaks.
ð Replace the detergent.
