The HERMetic Sampler GTX Chem is a portable, gas-tight liquid sampler designed for closed-system chemical sampling, preventing gas release during operation. It enables safe liquid transfer from the sampling bottle to a laboratory bottle by over-pressurizing the upper chamber with a pump. Ideal for spot, bottom, running, or zone sampling, it ensures representative and differentiated samples while maintaining a sealed environment. Compatible with 2-inch HERMetic compact valves, its gas-tight construction prevents pressure release and fume exposure, ensuring operator safety. Certified for explosive environments (Zone 0), it supports specialized sampling bottles for various needs in petrochemical, pharmaceutical, and industrial applications.
