Foreline Traps Optically-Dense Traps •Economical—Lowest price of any foreline trap. •No maintenance—Eliminates bakeout, LN2 cooling and attention. Operating Principles The TLI optically-dense foreline trap is economical, and relies for its trapping effect on a large area of metallic adsorption characteristics. A molecule can only pass through the optically-dense foreline trap by contacting the adsorbent material a great number of times, thereby greatly increasing the probability that it will be trapped. Materials The optically-dense traps are made of type 304 stainless, TIG welded. They are supplied in three different configurations— 1)hose connections only (unflanged), 2)hose connection one end, other end flanged, and 3)flanged at both ends. Flanges are copper-gasketed compatible type, which mate with all other standard copper-gasketed flanges. Special flanges, such as ASA, can be supplied on request.
