Air Liquide ALPHAGAZ 2501 High-Purity Gas Regulator

The ALPHAGAZ 2501 specialty gas regulator is engineered specifically to meet the strict demands of laboratory, research, and analytical environments. Designed by Air Liquide’s specialty gases division, this high-performance regulator ensures point-of-use purity and ultra-stable pressure delivery for non-corrosive pure gases and critical calibration mixtures.

Featuring a premium barstock body construction and an advanced metal-to-metal diaphragm seal, the 2501 minimizes internal dead space and completely eliminates the risk of atmospheric diffusion or outgassing. Whether powering sensitive gas chromatography (GC) systems, calibration setups, or analytical instrumentation, the ALPHAGAZ 2501 delivers the reliable, drift-free flow your data depends on.

Features:

Ultra-Clean Service: Specially cleaned, tested, and certified oil-free for ultra-high purity (UHP) gas applications.

Contamination-Free Seal: Equipped with a premium stainless steel diaphragm and a metal-to-metal seal to guard against sample contamination.

Low Internal Volume: Engineered with minimal internal cavities to ensure rapid purging and prevent gas entrapment.

Dual Gauge Monitoring: High-visibility, heavy-duty dual gauges allow you to track remaining cylinder pressure and downstream delivery simultaneously.

Streamlined Installation: Ready for direct cylinder mounting or integrated inline point-of-use panel configuration.
