Gas Cylinders
Our company is endeavoring to help you in your research by charging small-sized gas cylinders with gaseous reagents for easy dispensing.
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.
- The charge intake cover should be attached after insuring that the gas flow has ceased.
- Select a low-temperature, well-ventilated place for storage.
- 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.
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.
Charge Valve and Connectors
To use these products charged in cylinder, Charge valve and Connectors which are sold separately are required.
(Connectors are used for connection between the reaction apparatus and gas cylinders)
Charge Valve
[Method of Use] (The actual form may differ slightly from the illustration.)
- Before mounting the charge valve, turn the handle (A) to the left and pull the needle (B) upward as far as it can go.
- Mount the charge valve on to the gas cylinder.
- After the charge valve is mounted, tighten the disk (C) attached at the bottom of the charge valve. Be careful not to over tighten.
- Turning the handle (A) to the right makes the needle (B) come down and perforate the sealing lid.
- On turning the handle (A) to the left, the valve opens to allow the gas to flow.
- To stop the gas flow, turn the handle (A) to the right. Do not remove the charge valve until the cylinder is empty and the inside pressure becomes equal to atmospheric pressure.

Connectors
[Method of Use]
- Detach the charge intake cover from the charge valve.
- Set the cap nut in the connector. Then, mount them in the charge intake.
- Confirm that the connected side of the connector and the charge intake are normal. Afterwards, tighten the cap nut with the spanner etc. Be careful not to over tighten.
- Use a commercially available tube fitting suitable for the outside diameter of the pipe connector when connecting to the gas introduction pipe of the reactor.
We have two types of connectors, a tube connector for under ordinary pressure and a pipe connector for under increased pressure. The outside diameter of both connectors is 6.0 mm. Each connector is bundled with a cap nut. Please use both connectors according to the situation.
