QUANTITY CONTENTS CODE<br />
1 UV Safety Goggles 31041<br />
1 Penray UV Lamp 31041-1<br />
1 Renray Lamp Power Source 31041-2<br />
Proper safety precautions must be followed when using the Penray UV lamp<br />
and power source (31041-1 and 31041-2) to prevent eye and skin damage.<br />
Always wear the UV Safety Goggles (31041) while the lamp is turned on.<br />
Never handle the lamp itself; always hold it by the socket. Wipe the lamp dry<br />
with a clean, soft tissue after each test. Do not operate the lamp outside the<br />
Erlenmeyer Flask filled with water.<br />
Benzotriazole and tolyltriazole form strong complexes with metals. They are<br />
used in antifreeze for cars, lubricating oil, and photographic anti-fogging<br />
agents. In cooling water systems benzotriazole and tolyltriazole are used as<br />
corrosion and rust inhibitors together with many kinds of scale inhibitors,<br />
bactericides and algaecides.<br />
APPLICATION: Corrosion and rust inhibitors in cooling water systems<br />
RANGE: 0.0 – 30.0 ppm Benzotriazole<br />
0.0 – 30.0 ppm Tolyltriazole<br />
METHOD: Benzotriazole and tolyltriazole are UV-photolyzed in a<br />
buffered solution with a pH between 4 and 6. A yellow color<br />
develops in proportion to the concentration of triazole<br />
present.<br />
