Gas sample bags are a convenient and accurate means of gas and vapor samples in air. This is particularly true in areas where the concentration is above the detection limits of common analytical instruments. Many chemical hazards can be effectively collected by sample bags. But, while the collection method is simple, the selection of the bag, fittings, and tubing is critical.

• Tough & Flexible
  Tedlar film retains its tensile strength and toughness allowing for reuse and a long service life for many applications. Tedlar is rated for continuous use from -98 to 225 F. This wide range of operation allows for use in very cold or very hot environments including stacks, vents, and flues.
  
  
• Chemically Inert
  Tedlar film is inert to a wide range of chemicals. Since Tedlar will not react with or alter the composition of collected chemicals, sample integrity is assured.
  
  

	Tedlar Bags with Single Polypropylene Fitting These industry standard sample bags utilize a lightweight, patented single fitting of inert polypropylene that combines the hose/valve and the septum holder into one compact fitting.
	Tedlar Bags with Single Stainless Steel Fitting These economical sample bags feature a unique stainless steel fitting that reduces the overall weight of using stainless steel by combining the hose/valve and septum fittings into one easy-to-use unit.
	Tedlar Bags Dual Stainless Steel Fittings This flexible bag system features two stainless steel fittings: the hose/valve for flushing, filling, and sealing the bag;and, the septum with a syringe port for removing samples for analysis. The fittings are easy-to-use and provide sampling flexibility and reliability.

• Wide Temperature Range
  FluoroFilm bags are ideal for stack sampling. FluoroFilm performs over the temperature range of -400 to 400 F (-240 to 205 C) which is suitable for all stack sampling applications..
  
  
• Inert to a Broad Range of Chemicals
  FluoroFilm is the most chemically-inert of all the plastics. In fact, FluoroFilm film is solvent-resistant to virtually all chemicals except molten alkali metals, fluorine at elevated temperatures, and certain complex halogenated compounds such as chlorine trifluoride at elevated temperatures and pressures.

	FluoroFilm Sample Bags with PTFE Fitting Gas sample bags made of FluoroFilm are the most chemically-inert of any bag material and offer the ultimate performance in bag sampling. The PTFE fitting combines the hose/valve and the septum holder into one compact fitting.
	FluoroFilm Sample Bags with Stainless Steel Fitting All the benefits of FluoroFilm, the most chemically-inert bag material, plus convenience and economy of stainless steel fittings. The single stainless steel fitting combines the hose/valve and the septum holder into one compact fitting.

• For Sampling Low Molecular Weight Compounds
  FlexFoil Grab Bags provide light and moisture protection for low molecular weight compounds such as hydrogen that are unstable when collected into standard Tedlar bags. To prevent permeation in and out of the bags, SKC FlexFoil Grab Bags are specially designed with four layers of material. The inside surface is inert, minimizing absorption and adsorption of compounds.
  
  

Stainless Steel or Polypropylene Fitting SKC FlexFoil grab bags are available with either a single inert polypropylene or Stainless Steele fitting that combine the hose/valve and the septum holder into one compact fitting.

Tedlar Bag Accessories

	The SKC Vac-U-Chamber ™ The SKC Vac-U-Chamber is a rigid air sample box allowing the direct filling of an air sample bag using negative pressure provided by most personal air sampling pumps.
	The SKC Vac-U-Tube ™ An easy way to take quick bag samples, the SKC Vac-U-Tube is an acrylic syringe with a removable face plate that allows a specially-designed 0.7 L Tedlar bag to be placed inside.
	PTFE Tubing Use only PTFE tubing for bag sampling to prevent loss through adsorption to the tubing surface

Contact your SKC representative for more information or call the SKC Sales Department at 281-859-8050 for a quotation on custom bags.

	When sampling for light-sensitive compounds, use black and clear layered Tedlar® bags.
	Use only PTFE tubing and PTFE-lined septums for bag sampling.
	Flush the bag thoroughly with purified air or nitrogen before using.
	Do not use bags to collect unstable or highly reactive compounds.
	Do not ship sample bags by air unless the cargo cabin is pressurized.
	Avoid filling the bag more than 80% of its maximum volume. At the end of the sampling period, turn the pump off and close the valve on the bag.	Avoid overfilling bags
	Sample bags are not intended for the storage of hazardous materials. If you suspect that your sample bags may contain hazardous materials in concentrations above the safe levels defined by NIOSH, OSHA, or DOT, you may need to refer to special federal and state packaging and transportation regulations.
