Precision Calibrated Butane Gas Valve for Laboratory Gas Chromatographs with Needle-Valve Accuracy

Achieve the pinnacle of analytical accuracy with our Precision Calibrated Butane Gas Valve for laboratory gas chromatographs. This exquisite gas control mechanism is engineered with a needle-valve design, allowing researchers to make infinitesimally fine adjustments to the carrier or fuel gas flow rate. Such precision is fundamental to obtaining reproducible peaks, stable baselines, and reliable quantitative results in sensitive analytical chemistry applications.

Crafted for the exacting demands of the laboratory, this butane gas valve is made from ultra-clean, non-outgassing materials to prevent sample contamination. It functions as a metering-grade gas flow regulator, providing unparalleled stability and control over gas streams measured in milliliters per minute. The needle valve assembly, a specialized form of gas appliance fitting, ensures that the set flow rate remains constant over time, which is critical for experiments that can run for hours or even days.
