Page 9: Vacuum Sealing Agents
PERATION Vacuum Sealing Agents • High temperature vacuum grease is often nec- essary to provide a proper seal at tubing con- nections, valve connections, door seals, etc. This is especially important at high vacuums. Using silicone vacuum grease will damage the door seal and has restrictions for some types of materials placed in the oven.. - Page 10 PERATION • The oven is equipped with silicone door gas- kets. Do not use silicone door gaskets or vacu- um grease when evaporating solvents in the oven or when using high aniline point oils. BUNA-N gaskets should be used in applications when evaporating solvents or when using high aniline point oils.

If the oven fails to maintain set temperature, it may indicate a problem with the Temperature Control, or possibly a heating element failure. If this occurs contact your local Fisher Scientific service representative at (1-800-395-5442). • Gaskets should be checked periodically for hardening, shrinking, deterioration or other signs of wear. -
