Overview

OSZS New Devex Film is a specialized membrane developed by our company for use in sampling bags. Tailored to meet specific customer needs, this film is created in collaboration with several specialized companies using internationally advanced film-making technologies. With a thickness of approximately 75µm, it is thinner than aluminum-plastic composite films, yet offers significantly better elasticity, preventing issues of hardening and brittleness in cold conditions. Most importantly, the New Devex Film has a low background, resulting in minimal contamination of gas samples, thus satisfying high customer standards for sampling bags. Compared to aluminum-plastic composite films, New Devex Film boasts advantages such as lower background, reduced contamination of filled gas samples, superior elasticity, affordability, and high cost-effectiveness. Testing by authoritative institutions shows that the performance of New Devex Film greatly exceeds that of aluminum-plastic composite films, making it the ideal specialized membrane for gas sampling bags, widely adopted by customers and currently the most cost-effective option worldwide.

Standard aluminum-plastic composite films are made from solvent-based adhesives that release a significant amount of volatile organic compounds (VOCs), undoubtedly contaminating gas samples. In contrast, the inner layer of New Devex Film uses eco-friendly adhesives, resulting in low VOC emissions that prevent contamination of gas samples and avoid interference with analytical data. The residual organic solvent content in New Devex Film is between 0.1mg and 0.3mg/m², which is only 5% of that found in aluminum-plastic composite films, making it a high-performance replacement.

Applications of New Devex Gas Sampling Bags:

Suitable for stable, low-reactivity gases such as petrochemical cracking gas, natural gas, coalbed gas, flue gas, ambient air, and process reaction gases, widely used in petrochemicals and environmental monitoring for gas sample collection and preservation. These bags ensure stable low concentrations (ppm levels) for 1 to 3 months.

Applicable for the collection and detection of total non-methane hydrocarbons.

Can hold low concentrations of industrial gases such as hydrogen (H2), oxygen (O2), nitrogen (N2), argon (Ar), methane (CH4), carbon monoxide (CO), and carbon dioxide (CO2).

Not recommended for highly reactive, corrosive, or oxidizing gases such as nitrogen oxides, strong alkaline gases, and halogen gases; also not advisable for very low concentrations like ppb levels.

Suitable for light-sensitive gas sampling that requires protection from light.

Standard sizes for the Aluminum-Foil (Multi-Layer) Gas Sampling Bags range from 0.5L to 6000L, with custom sizes and configurations available upon request.

more details

Side-opening stopcock valve

The OSZS side-opening stopcock valve on the Devex Multi-layer gas sampling bag features inlets and outlets that are parallel to the film plane, with an external sampling tube having an outer diameter of 6.3 mm.

The valve includes a sampling cap with a silicone rubber septum, which is isolated from the gas inside the sampling bag by the valve mechanism. The silicone septum is exposed to the gas only when the valve is in the open position. To extract a gas sample using a sampling needle, rotate the valve handle to align it with the sampling cap, allowing the gas inside the bag to come into contact with the silicone septum. Once sampling is complete, rotate the valve handle 90 degrees to close the valve, thus isolating the gas inside the bag from the septum.

This design ensures that the silicone rubber septum does not remain in extended contact with the gas, thereby mitigating the risk of septum corrosion or sample contamination.
