Full Description

A multi-layer foil gas sampling bag (Multifoil gas sampling bags) is a low-cost sampling bag (air sampling bag) with four protective film layers. Outward to inward, the bag has one layer of 60 gauge nylon, two layers of 0.0003-inch thick aluminum foil, and one layer of 0.002-inch thick роlуеthуlеnе. Since primarily it consists of aluminum film, researchers also call it an aluminum-foil gas sampling bag. The Multi-foil gas sampling bags show reliable stability for gases of lower molecular weights. It is excellent alternatives to the traditional canisters, useful for collecting indoor and outdoor air samples. Air sampling is an important activity to check the quality of air according to government norms. It also utilizes to examine part-per-billion (ppb) to part-per-million (ppm) levels of various types of gases, keeping air quality under control by taking necessary measures to reduce pollution.
At Techinstro, we sell pack sizes of 5, 10, 25, 50, 100 pieces of Multi-layer foil gas sampling bag. We produce these bags in a volume of 500ml, 1 liter, 2 liter, 3 liters, and 5 liters. The valve is made up of polypropylene (PP). It is also durable for air transport and has moisture-free packing.


• It helps to protect the air sample from heat and moisture.
• It is leakproof and does not emit any gas.
• The samples last for almost 72 hours. However, we suggest that the researchers test the sample at the earliest.
• It is chemically inert and does not contaminate the air samples.
• It is tough and flexible and can tolerate a temperature range from -72° to 107°C.
• It is easy to use and handle.


• It is useful in collecting and transporting gases like methane, carbon, carbon dioxide, carbon monoxide, and permanent gases.
• It is helpful to collect indoor, outdoor, and stationary gasses.
• It helps to check air pollution by power plants, workstations, work environments, and many more.

How to use it?

• The Multi-layer foil gas sampling bag has a nozzle on the top of the bag. Attach it to the valve and open it.
• It is advisable to fill the bag 80% of its capacity, or else there is a risk of the bag bursting due to varying air pressure in the bag.
• Close the valve and detach the bag once it has filled. Do not disconnect the bag without closing the valve.
• Researchers can also use a low-flow аіr ѕаmрlе pump for easy filling of the bag.

Safety Measures

• As the gas sampling bags are reusable, the researchers should consider that the bag should be clean before use. To clean the bag, researchers can flush nitrogen in the bag.
• Remember to take two bags for the same sample so that if one bag bursts, the second sample remains.
• The gases that work with are dangerous and hazardous if they come in contact with the human body. The operator should always wear protective equipment such as gloves, masks, eye-protecting goggles, face shields, and PPE kits.
• If one inhales the gas accidentally, rush to open air. If anyone faints, give mouth-to-mouth respiration and run to the hospital immediately.
• If the gases come in contact with eyes, rinse eyes with cold water. If irritation persists, seek medical advice.
• The air sampling bags hold air samples effectively for 48 hours. Make sure that they reach the lab before it.
