Celvacene Medium Non-Silicone High Vacuum Grease is a brownish-yellow transparent grease with a minimum melting point of 120°C. It is recommended for ground-glass joints and other vacuum seals under conditions where a lighter grease may be sucked through. This grease is especially useful for treating rubber gaskets, soppers, and tubing to form a vacuum-tight bond with metal or glass surfaces. Rubber thus bonded is easily removed by feeding castor oil between surfaces with a thin-bladed instrument. On continuously evacuated systems, pressures of less than 10-6 torr can be obtained.
