Description

Ideal with ultra-high–purity carrier gas for sensitive GC applications using MS, PID, HID or ECD detection methods.

• Brass construction for minimum dead volume
• Oxidation-resistant chrome plating
• 10μm sintered bronze filter, metal-to-metal seals for long-term leak tightness, and PTFE-resin seats
• Type 316 stainless-steel regulator diaphragm with 1/4 in. FPT-fitting outlet-valve ensures ultra-high–purity control of gases and leak-free shutoff
• 2 in. (5.1cm) dia. gauge displays pressure in psi/kPa
• Multiturn shutoff handle
• Helium leak-test–certifiable to 2 × 10^-8cc/sec
• Operating temperature range: -4° to +60°C (24.8° to 60°F)
• Fully assembled and tested

• Single-stage regulators: Use where there is secondary pressure regulation downstream Dual-stage regulators: Recommended for stable outlet control when using high-pressure gas-cylinders (secondary pressure regulation not needed)
