TCLP (Toxicity Characteristic Leaching Procedure) is a method to predict the impact of a landfilled waste on the underlying groundwater. You can find a wide range of equipment and supplies for your leaching procedure. The LE Environmental Rotator for TCLP extractions is robust and able to handle up to twelve ZHE's or extraction bottles. TCLP filters meet the EPA method by being pre-acid washed to meet method requirements. For organic extractions, our ZHE is the only product that allows the use of the maximum sample size prescribed by the method. We also have the supplies you need including bottles, filters, syringes, pumps, Tedlar® bags, and fittings.
