Gas Sampling Bags for Laboratory Air & Gas Collection

Gas sampling bags are essential laboratory consumables designed for safe collection, storage, and transport of gas samples without contamination or chemical reaction.

They are commonly referred to as:

• Air sampling bags
• Gas collection bags
• Laboratory gas sampling bags

What Are Gas Sampling Bags?

Gas sampling bags are flexible, sealed containers made from chemically inert materials such as Tedlar, multi-layer foil, or Teflon (FEP). They are designed to maintain the original composition of gas samples during transport and analysis.

They are widely used for collecting:

• Ambient air samples
• Industrial exhaust gases
• VOCs (volatile organic compounds)
• Calibration gases
• Environmental emission samples

Key Functions of Gas Sampling Bags

Gas sampling bags are designed to ensure:

• Chemical inertness (no reaction with gas samples)
• Low permeability to prevent gas loss
• Stable storage for laboratory analysis
• Portable sampling for field collection
• Compatibility with GC/MS analysis
