Braycote® Micronic 803 and 803 Vacuum Grease

perfluoroether greases
wide temperature range
low volatility
ultra-high vacuum applications
Braycote® Micronic 803 is filtered for ultimate cleanliness. It will provide the kind of purity required for use with vacuum systems employing LaB6 filaments.

It is stable under high vacuum and has a temperature range of -63°C to 232°C (below 80°F to >499°F). 803 Micronic was developed for applications involving long-term exposure where high temperature or hard vacuum is expected. It is acceptable for clean room applications.

Standard Braycote® 803 has nearly the same specifications and does withstand high temperatures and is used for hard vacuum. Both types exhibit excellent shelf life because of their inertness.

Dow Corning® High Vacuum Grease

High vacuum grease, general lab lubricant use

Dow Corning® High vacuum Grease is a stiff, non-melting silicone lubricating material which has temperature range of -40ºC to 200ºC. Although it has a good stability at the higher end of the temperature range than most hydrocarbon greases, it shows a higher outgassing rate at room temperature. It can be used for high vacuum systems up to the 1x10^-6 mbar (1x10^-6torr) range. Due to it's initial outgassing, it is recommended to condition vacuum system before use. Not for use in electron microscopes. Also not recommended for use in evaporators which need to be Si free. The Dow Corning® High Vacuum Grease is the equivalent product to Dow Corning® 976 of 976V High Vacuum grease. Other applications include lubricant for glass stopcocks, glass joints, glass rubber connections and O-rings on binoculars. Shelf life is 60 months from date of manufacture for unopened containers and stored at normal warehouse conditions.

Celvaseal™ Vacuum Leak Sealant

Celvaseal™ leak sealant is a compound specially engineered for sealing leaks in high vacuum systems. It can repair leaks as large as 2 micro liters/second, even with the system under vacuum. Larger leaks can be repaired when the vacuum system is at atmosphere.

It is available in two forms: Spray (ozone safe) and fluid in a brush-on bottle. It has a low vapor pressure which make is suitable for use in ultra high vacuum systems and withstands repeated temperature cycling from -200°C to 400°C. (-328°F to 752°F) Steady weight loss of 1.6 x 10^-8 gr/cm²/hr, which is lower than most epoxy based systems. Can be used at temperatures up to 300°C (572°F) continuously, and up to 400°C (752°F) for short periods. It has good adhesion to cryogenic temperatures and excellent electrical resistivity. Can be stored longer than 1 yr at 25°C (77°F). Density is 1.14 gr/cm³ and viscosity is 250-1000 cPs.

Hysol® Vacuum Sealant Kit

Hysol® Low Vapor-pressure Epoxy Resin Sealant seals small leaks on any type of vacuum system or component quickly and conveniently. It is a two component system resin, free of any solvents. It can be used at pressures of 10^-9 or below and at temperatures between -45°C (-49°F) and +120°C (248°F) (baking temperature). It bonds well with many materials such as metals, ceramics and glass. Equivalent to Torr Seal^® resin sealant.

Kit contains tube of resin, tube of hardener, 10 mixing cups and 10 wooden stirring sticks.
