General description

Tedlar is recommended in several US EPA methods for sampling VOCs and sulfur compounds. Our Tedlar is made from a high-quality 2 mil Tedlar film for superior inertness, impermeability, sample integrity and good recovery data. Our Push Lock Valve (PLV) and seam-sealing process ensure that these bags are sturdy and virtually leak-proof, even under the most demanding sampling and shipping conditions.

The EPA Toxicity Characteristic Leaching Procedure (TCLP) was implemented in 1990 for determining the mobility of organic and inorganic contaminants present in liquids, solids and multiphasic wastes. The TCLP provides a method to determine the potential for any waste leaching in a landfill environment;, according to this procedure, a pressure driven piston system, Zero Headspace Extractor (ZHE), forces liquid waste through a glass fiber filter and into a Tedlar bag for subsequent analysis.

Supelco offers our disposable 1 Liter Tedlar bag for use with the Zero Headspace extractor (ZHE). It features a single stainless steel septum fitting that is designed to be connected to commercially available extractor vessels using a special stainless steel adapter (not sold by Sigma-Aldrich).
