Whatman* Acid-Treated Low-Metal TCLP Filters

Toxicity characteristic leaching procedure (TCLP) is an analytical test designed to determine the leaching potential in a landfill for hazardous organic and inorganic contaminants that could potentially migrate into groundwater, threatening drinking water sources. This TCLP filter is a binder-free borosilicate glass microfiber with a particle retention rating of 0.6 µm to 0.8 µm, as specified by EPA Method 1311. The 90 mm diameter filter is required for volatile samples and use with a zero headspace extractor. The 142 mm filter is typically used with nonvolatile samples in an approved jar.
