Filter Papers for TCLP (Toxicity Characteristic Leaching Procedure)
Filter papers for TCLP are specially selected filtration media used during EPA Method 1311 to separate solid residues from TCLP leachate. They ensure accurate, compliant, and reproducible results in hazardous waste and environmental testing.
TCLP filter papers are typically glass microfiber or quartz microfiber filters, chosen for their chemical resistance, high loading capacity, and low extractables. They are designed to handle particulate-heavy samples without clogging while maintaining consistent filtration.
