Whatman Acid Treated Low Metal TCLP Testing 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. By accurately characterizing the degree of contamination, material can be disposed of as safely and economically as possible.

To dispose of hazardous waste in a United States municipal landfill, TCLP limits must fall within standard levels set for maximum contamination levels (MCLs). If MCLs are exceeded, the producer must dispose of the materials at a specialized hazardous waste facility, which increases costs significantly. Acid-treated, low metal Whatman TCLP test filters from GE Healthcare’s Life Sciences business can help to determine what steps, if any, must be taken to mitigate landfill leachate risk.

The Whatman TCLP Filter is manufactured using a binder free borosilicate glass microfiber with a particle retention rating of 0.6 to 0.8 μm. These acid treated, low metal filters are available in a variety of diameters. The 90 mm 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.
