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.
