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 Capacity (mL) : 5000 Diameter (mm) : 205 Overall Height (mm) : 373 Case Qty : 1 ProductExpirationType : Does Not Expire ProductSiteLaunchDate : 2013-11-15T00:00:01-08:00 Size : 1-3/4 in X 50 ft StreetDate : 2017-05-15T00:00:01Z SupplierDeclaredDgHzRegulation : unknown TemperatureRating : Ambient: 15 to 25 C (59 to 77 F) UnitCount : 1 UnspscCode : 40142000
