High-Performance Extraction for EPA Method 1311 Compliance
Streamline your environmental testing with the Environmental Express ZHE+ Zero Headspace Extractor. Engineered specifically for Toxic Characteristic Leaching Procedure (TCLP) analysis, this system ensures strict adherence to EPA Method 1311 standards, delivering accurate and reproducible results for volatile organic compounds.
Engineered for Safety and Precision
The ZHE+ features an intelligent built-in safety mechanism: the system will not pressurize unless it is completely assembled, protecting your laboratory personnel and your samples. An integrated pressure gauge allows for real-time monitoring of filtration pressure, giving you total control over the extraction environment.
Premium Materials & Seamless Operation
Built to withstand harsh laboratory conditions, the finished extract exits through a high-grade 316 stainless steel plug located on the top plate, minimizing contamination risks. During operation, an internal piston seamlessly drives the sample upward, allowing for efficient gas collection into a Tedlar® bag or a gastight syringe.
