VACUUM APPARATUS made with Kontes "O" Ring Connectors requires minimum displacement to assemble, avoids lubricants, and holds vacuums of 10- 6 mm of Hg. LUBRICANT FREE connections are obtained because the hemi- spherical connector arms are separated, but sealed by a Buna-N or Viton® "O" Ring*—not by a grease. This avoids sticking and freezing problems associated with ground glass joints. METAL TO GLASS coupling is a simple matter now using a stand- ard glass connector and a standard brass or stainless steel connector. Compared to graded metal and glass seals, the rug- gedness and flexibility of such connections are particularly impressive. *0ptional Viton "0" rings, which are recommended for service with steam, silicone greases, and oils, are also resistant to oxygen and ozone. The temperature limit using Buna-N is 150°C—with Viton 300°C. intermittently, 200°C. continuously. ©Viton is a registered trademark of E. I. duPont Co.
