Liquid Sampling Valve

Allow for visual observation of all reactions and aerosols under pressure PVC coated glass minimizes potential hazard Additional protection furnished with optional clear plastic shield - highly recommended 1/8” NPT Threaded hole in needle valve adaptor (4967A66, not included) takes valve fittings for controlled charge, pressurization or contents release, allowing many test parameters Reaction vessels are available in three standard capacities: 3 oz., 6 oz. and 12 oz. CAUTION: safety precautions should be used with glass under pressure. Maximum safe pressure depends on service conditions. Pressure rating of the vessels decreases 0.25 psi per° F over room temperature. Surface scratches on glass cause weakening. ADDITIONAL SHIELDING IS STRONGLY RECOMMENDED. Pressure for new bottles should not exceed 225 psi for 3 oz., 100 psi for 6 oz. and 75 psi for 12 oz. size. Aerosol Reaction Vessel (4967A02 to A06) Complete with coupling, polyethylene insert, o-ring and a millimeter reference scale 3 oz. vessel is tubular; larger sizes are bottle shaped with constricted neck Aerosol Reaction Vessel, rounded bottom (4967A08 to A12) Complete with coupling, foot and millimeter reference scale Without valve adapter, see Thomas number 4967A66 Aerosol Reaction Vessel (4967A14 to A18) Complete with coupling, clear plastic shield and millimeter reference scale Without needle valve adapter, see 4967A66. Aerosol Reaction Vessel Only (4967A20 to A24) With millimeter reference scale Used in Thomas numbers 4967A02, A04 and A06 PTFE Insert (4967A58 and A60) To replace polyethylene insert for higher temperature applications Multi-ported Stirring Assembly and accessories (4967A62 and A64) Allows changing of test parameters while reactors are under pressure Particularly well-suited for gathering chemical reaction data of heterogeneous materials Provides controlled and constant stirring capability Permits utilization of gauges for pressure control, internal temperature readings and allows injection or extraction of samples easily. Supplied with a 12 oz. bottle. Needle Valve Adapter (4967A66 to A70) Stainless steel 1/8” NPT Fluoropolymer elastomer O-Ring (4967A72) To replace neoprene O-ring (Thomas number 4967A70) for more corrosive applications
