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
· Side neck allows addition of filtered solvent without removing delivery cap
· 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
