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 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
