【Characteristics】
• The flow of gas can be adjusted across a wide range.
• Convenient for moving since gas cylinders are small sized (7 × 14 cm) and lightweight (under 500 g).
• Metallic pressure-tight container (14 kg/cm²).

【Storage Method】
Store in a cool place before opening and use the compressed reagent as soon as possible.* One-time, exhaustive use is recommended. If the reagents need to be stored, please keep the following in mind with the utmost caution.
*The valve packing may swell in storage and gas might not flow out.

1. The charge intake cover should be attached after insuring that the gas flow has ceased.
2. Select a low-temperature, well-ventilated place for storage.
3. Reagents that require refrigeration should be stored only in an explosion-proof refrigerator. Potential risks for explosion through ignition of a small gas leak from the spark of the thermostat may be present in ordinary refrigerators.

B0748 1-Butyne can decompose explosively so these reagent cylinders should not be stored for re-use.

【Notes】
• These reagents are pressurized. Sufficient care should be taken in handling them, in addition to wearing appropriate protective equipment.
• Take care to insure that the inner pressure of reaction apparatus does not exceed the inner pressure of the gas cylinders. As an extra precaution, we recommend that a check valve be attached within the gas introduction path.
• Empty the contents thoroughly before disposing of the gas cylinder.
