Aldrich^® lecture-bottle station

For strong, acid-forming gas applications, such as hydrogen chloride, hydrogen bromide, hydrogen fluoride, and silicon tetrafluoride. Cross-purge valve sits between the lecture-bottle and regulator to prevent escape of toxic and flammable gases when changing cylinders and permits purging system with inert gas to remove air, moisture, and process gas to minimize gas hydrolysis and corrosion damage to equipment. Purge system with dry, inert gas before introducing corrosive gases and again immediately after use. SWAGELOK tube connector, 21979-U sold separately, is required when using with corrosive gases.

Regulator specifications:

Single stage, panel-mounted electroless nickel-plated brass body with PTFE-lined stainless steel pressure diaphragm, Monel nozzle with PCTFE seat, Viton seals, captured vent for safe operation (1/4 in. NPTM connection), 2.7 in. diameter stainless steel gauges, helium leak rate tested at 1 x 10^-6 ssc/sec., 3000 psig maximum inlet pressure, 0-80 psig delivery range, Stainless steel outlet needle valve with 1/4 in. MNPF connection.

Cross-purge valve specifications:

316L stainless steel body and diaphragm-seal valves with color-coded handles, welded construction, electropolished and cleaned for oxygen service, 3000 psig maximum inlet pressure with 1/4 in. NPTF connections.

Dispensing lecture-bottle gases has never been safer or simpler using these portable lecture-bottle stations. The premium quality components housed within a station are matched to the application, fully assembled, leak-tested, and ready for use.

Just connect the station to the lecture-bottle, process, and a source of inert gas, if using a station with a purge valve, and you are ready to go.

Safe and Simple:

• Gas dispensing and storage in one compact, portable system
• Keeps lecture-bottles upright and stable, eliminates tip-over
• Reduces equipment damage and chance of personal injury
• Choice of four models matched to the application
