ULTRA-WARE® Five Valve Recirculation/ Filtration Caps Standard - 953983-0047
ULTRA-WARE® Plastic-Coated HPLC Reservoirs ULTRA-WARE® reservoirs have been specially designed for the preparation, storage and delivery of all liquid chromatography mobile phases. • Manufactured from the most chemically inert glass available to prevent the leaching of any extractables into the mobile phase solvents, then externally coated with a safety plastic with an added ultraviolet (UV) blocking agent • In case of an accident, the plastic safety coating helps retain glass fragments and allows a reasonable amount of time for the safe disposal of the liquid contents • Plastic coating also blocks virtually all UV light up to 385 nm, preventing photo-degradation of light-sensitive reagents • Recommended for use under vacuum for filtration and vacuum degassing of mobile phase solvents • Can also be used at internal pressures of up to 6 psig for helium sparging and blanketing of the mobile phase • Conical bottom reservoirs deliver virtually all of the mobile phase without dangerous reservoir tilting • All ULTRA-WARE® reservoirs are supplied with GL 45-4 screw thread • Plastic coating is PVC with a UV blocking agent • Patent No. Des. 292,824 • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

Patent No. 5,397,467
Specially designed to permit the recirculation of mobile phase back into the reservoir while maintaining the helium sparged environment. This cap also performs stepwise filtration, sparging/degassing, storage and delivery to the HPLC pump An integral check valve prevents mobile phase from backing up into the gas lines
•
•
• A pressure release valve protects the reservoir from being accidentally over-pressurized • The 1/4”-28 fitting connections allow easy connection to any HPLC pump system • Cap body is manufactured from glass-filled PTFE • Cap will fit any reservoir or bottle with a GL 45 thread

Patent No. 5,397,467
Tetrahydrofuran (THF), widely used as a mobile phase for GPC, attacks the CTFE valve stems and TFE/propylene o-rings used in the standard Five Valve Cap This special THF-resistant version has 316 stainless steel wherever the standard system has CTFE, and FFKM o-rings in place of the TFE/propylene o-rings This cap is also recommended for aggressive organic solutions such as chlorinated hydrocarbons, ethers and ketones Cap body is manufactured from glass-filled PTFE Cap will fit any reservoir or bottle with a GL 45 thread
