Nalophan bags

Nalophan bags are specifically designed to meet the quality requirements of EN 13725:2003 and ISO 17025, minimizing the risk of contamination in odour samples.

The bags are available in the following sizes:

• 10 liters (per 10 bags)
• 30 liters (per 5 bags)
• 60 liters (per 5 bags)

Each bag has a PTFE tube at the end that can be used to fill the bag. The bags are supplied with PTFE caps to close the tubing.

We have these Nalophan bags available from stock.

High-Quality Nalophan Gas Sampling Bags

Our Nalophan gas sampling bags are high-quality sample bags manufactured by Olfasense GmbH (Germany). They are specially designed for the short-term storage and transport of air and gas samples in applications such as odour testing, environmental monitoring, and emissions research.

Each bag is equipped with a PTFE tube at one end for convenient sample collection. The bags come with PTFE caps to securely close the tube after sampling.

Each bag is individually tested for odour and leakage, and then vacuum-packed to ensure cleanliness and integrity.

Nalophan Film

Nalophan sampling bags are made from Nalophan, an odourless, transparent nylon film (PA) with low gas permeability. One of the main advantages of these bags is their ability to prevent loss or contamination of the gas sample. Thanks to its low diffusion rate, Nalophan is effective in preserving the integrity of the sample by preventing gases from entering or escaping the bag.

Standards & Compliance

The bags are made from Nalophan (nylon, PA) and equipped with PTFE tubing to minimize reactions with sulphur compounds. In compliance with ISO 17025, Nalophan bags have been tested in accordance with section 6.3.2 of the European standard EN 13725:2003 and section 4.3.1 of the German guideline VDI 3880:2011. As such, these bags are the industry standard for odour sampling.

Nalophan Bags & PureSniff Compatibility

The PTFE tubing ensures a chemically resistant and odourless connection to pumps or analytical instruments. After filling, the tube can be sealed with the supplied PTFE cap.

Nalophan sampling bags are compatible with a wide range of analytical instruments, allowing for easy and accurate analysis of gas samples. They are suitable for sampling volatile organic compounds (VOCs), greenhouse gases, and other gaseous substances.
