Gas sampling bag Aluminum foil sampling bag Gas sampling bag

Aluminum foil gas bag (gas-phase consumable) usage:

Gas sampling bags, also known as gas sampling bags, are widely used for gas sample collection and preservation in fields such as petrochemicals, environmental monitoring, and scientific experiments. Aluminum foil gas sampling bag is made of multi-layer aluminum foil composite film, which has the characteristics of low permeability, good airtightness, low adsorption, stable chemical properties, simple operation, and lightweight and easy to carry.

This airbag is suitable for filling various mixed gases, such as general industrial gases, petrochemical gases, environmental detection gases, etc. After investigation, it has been shown that the airbag can ensure constant low concentration (ppm level) components for 1-3 months, and can also store low concentration corrosive and chemically active gases in a short period of time.

Each aluminum foil sampling bag (gas-phase consumable) is equipped with a plastic switch valve or a metal switch valve. The plastic switch valve has two types: straight rod and lateral. The lateral switch valve is equipped with a needle sampling port, which can be directly sampled from the bag using a sampler. Multiple switch valves can also be configured according to customer needs (such as a combination of 1 straight rod and 1 side rod, or 2 straight rods or 2 side rods, etc.) for convenient inflation and deflation replacement.

Material model:

• Aluminum plastic composite film gas sampling bag,
• Devex gas sampling bag,
• Tedlar (PVF) gas sampling bag,
• PVDF gas sampling bag, FEP gas sampling bag,
• Fluode gas sampling bag

The commonly used specifications for sampling bags include 0.5L, 1.0L, 2.0L, 3.0L, 4.0L, 5.0L, 8.0L, 10.0L, 15.0L, 20.0L, and 30.0L. Various specifications of gas sampling bags can be made according to customer needs.

Usage and precautions:

&#61550； Straight rod switch valve airbag

1) The on-off valve is operated by the valve stem. When the valve stem rotates clockwise to the end, it is closed, and when it rotates counterclockwise to the end, it is open; The on-off valve can only be fully opened or fully closed, and cannot adjust the flow rate;

2) Replace the gas bag with sample gas or inert gas before use;

3) The inflation pressure should not exceed 3000pa; Intuitively observe that the airbag is fully inflated, but it is not very tight when pressed with fingers.

4) Operating temperature:- 30℃～+50℃；

5) When storing and using, keep away from open flames and high temperatures; Do not touch hard objects to avoid puncturing the membrane material;

6) Various interfaces, instruments, equipment, and devices should be connected using corresponding soft rubber hoses for transition;

7) When using the dual opening and closing valve, one in and one out can be used for easy cleaning of the airbag;

8) Collect or store corrosive gases, it is recommended to choose full plastic switch valve airbags.
