GAS MANAGEMENT
Gas Traps
High-Capacity Indicating Oxygen Trap
• Indicator changes from dark blue to black as oxygen and
water are trapped.
• Lasts longer than three smaller traps.
• Use with all carrier gases.
• Ambient operating temperature, 100 psi (689 kPa) operating
pressure.
• Built-in frit traps microparticles.
• Outlet gas purity:
O
2
< 0.1 ppm when inlet does not exceed 15 ppm.
H
2
O < 0.5 ppm when inlet does not exceed 10 ppm.
• Maximum operating pressure: 150 psi (1,034 kPa).
• Maximum flow: 16.5 L/min.

(23.5 x 5.1 cm)
Indicating Oxygen Trap
• Indicator changes from light green to grey as oxygen is
trapped.
• Heavy-walled glass body, protected by polycarbonate sleeve,
prevents oxygen and water infusion.
• Prepurged for fast stabilization.
• 100 psi (689 kPa) maximum operating pressure.
• Reduces oxygen to 0.1 ppm.
• 10 µm frits at inlet and outlet.
• Optimal flow rate: < 150 mL/min.
