General description

Do your waste samples contain volatile substances, such as isopropanol, acetone or xylene? Then use our ZHE (Zero Head Space Extractor) Hazardous Waste Filtration system, which is approved by the US Environmental Protection Agency (EPA) as an apparatus for Toxicity Characteristic Leaching Procedure (TCLP) measurement.

The system cannot pressurize unless completely assembled; this eliminates accidentally “shooting the piston” out of the unit and assures safe operation. Choose both manual and automatic venting modes.

Features & Benefits:
•Allows for pressurization of filter without introducing air, due to movable piston design
•Prevents loss of volatiles
•Manual and automatic venting modes
•System cannot be pressurized unless completely assembled, thereby preventing "shooting the piston" out of the unit accidentally
