What Does ZHE Stand For?

ZHE stands for Zero Headspace Extractor Used In TCLP Determinations

ZHE, or Zero Headspace Extractor Used In TCLP Determinations, is a specialized device designed for the extraction of leachate from solid waste materials in accordance with the Toxicity Characteristic Leaching Procedure (TCLP). This apparatus minimizes headspace to prevent the volatilization of contaminants during the extraction process, ensuring accurate and reliable results in assessing the environmental impact of hazardous waste. The ZHE is integral for laboratories conducting TCLP testing to determine the potential toxicity of waste materials before disposal or treatment.
