Whatman 1810-090 Filter Circles, 90mm Dia, Binder Free Acid Treated Low Metal TCLP, 50/pk

These filters are specifically designed for Toxicity Characteristic Leaching Procedure (TCLP) testing, which evaluates hazardous waste leachability. They help determine whether contaminants may migrate into groundwater, supporting EPA Method 1311 compliance and waste disposal decisions.

The filter is manufactured from binder-free borosilicate glass microfiber with low metal content. This construction minimizes contamination and provides high loading capacity with fast flow rates, making it suitable for trace-level environmental analysis.

These TCLP filters offer approximately 0.6–0.8 µm particle retention, meeting EPA TCLP requirements while maintaining efficient filtration. This combination allows accurate separation of fine particulates during leachate testing.

Acid treatment removes trace metals from the filter, reducing background contamination. This ensures more accurate detection of heavy metals and hazardous compounds when analyzing landfill leachate or industrial waste samples.

The 90 mm size is commonly used with zero headspace extractors and TCLP testing setups, especially for volatile samples. The larger diameter also supports higher sample throughput in environmental testing workflows.
