Equipment needed but not supplied:
1 UV Shielding Goggles 31041
1 Pen-Ray UV Lamp 31041-1
1 Pen-Ray Lamp Power Source 31041-2
Proper safety precautions must be followed when using the Pen-Ray UV lamp and
power source (31041-1 and 31041-2) to prevent eye and skin damage. Always
wear the UV Shielding Goggles (31041) while the lamp is turned on. Never handle
the lamp itself; always hold it by the socket. Wipe the lamp dry with a clean, soft
tissue after each test. Do not operate the lamp outside the Erlenmeyer Flask fi lled
with water.
Benzotriazole and tolyltriazole form strong complexes with metals. They are used in
antifreeze for cars, lubricating oil, and photographic anti-fogging agents. In cooling
water systems benzotriazole and tolyltriazole are used as corrosion and rust
inhibitors together with many kinds of scale inhibitors, bactericides and algaecides.
