                  Advanced Specialty Gas Equipment


                  Model SG3504LECTURE BOTTLE EQUIPMENT
                  Models SG3504, SG3505
                  Brass, High Purity, Miniature Lecture Bottle Regulators

                  These small lightweight regulators, designed for mounting directly on lecture bottles, are recommended for High and Ultra High Purity, inert and noncorrosive gas service. They are available in two delivery pressure ranges (4–75 and 5–150 psig) and with either CGA 110, 170 or 180 connections.


                  Standard Features
                  • Metal Diaphragm minimizes diffusion of air into regulator and eliminates "off gassing" associated with elastomeric diaphragms, thus maintaining gas purity.
                  • High Purity Regulator Design permits vacuum purging of regulator.
                  • Filter in Inlet traps foreign matter, extends regulator life and reduces maintenance.
                  • Compact Miniature Size provides for ease of use with lecture bottles.
