Description
The Oxygen (O₂) 2.0% Calibration Gas – Nitrogen Balance is a precision calibration gas mixture designed for calibration, testing, and verification of compatible oxygen detection and analytical instruments.
This calibration gas mixture contains 2.0% Oxygen (O₂), equivalent to 20,000 ppm, with Nitrogen (N₂) balance. It is available in a 34L cylinder with a CGA-600 connection and a 103L cylinder with a C-10 connection.
Each cylinder is manufactured in the USA and provides traceable documentation to support your calibration and testing program. Cylinders include a QR code providing convenient access from a smartphone or other compatible device to the cylinder-specific Safety Data Sheet (SDS) and Certificate of Analysis (COA).
Calibration gas is NIST traceable and produced under quality systems meeting ISO 17034:2016 for Reference Material Production, ISO/IEC 17025:2017 for Chemical Testing, and ISO 9001:2015 Quality Management standards.

Specifications and cylinder appearance may vary by cylinder size and production lot.
Common Uses: Calibration, testing, and verification of compatible oxygen detection, oxygen analysis, and analytical instruments requiring a 2.0% (20,000 ppm) Oxygen reference with nitrogen balance.
Always verify the required oxygen concentration, balance gas, cylinder connection, regulator, flow rate, and instrument response requirements, and follow the instrument manufacturer's calibration and testing procedures before use.
Hazardous Material Shipping
Calibration gas cylinders are regulated for transportation as hazardous materials and must be shipped in accordance with applicable carrier and hazardous-material regulations. Available shipping methods and charges may vary based on cylinder size, quantity, destination, and applicable HazMat requirements.
Lead Time
Please allow approximately 3 business days for order processing prior to shipment. Lead times may vary depending on availability and order quantity.
Non-Returnable Product
Calibration gas is non-returnable. Because calibration gas is a certified gas mixture with a limited shelf life, cylinders cannot be returned or exchanged after shipment.
Please verify the oxygen concentration, balance gas, cylinder size, and connection before placing your order.
Important Regulator Compatibility: The cylinder connections differ by size. The 34L cylinder uses a CGA-600 connection, while the 103L cylinder uses a C-10 connection. Verify that your regulator matches the cylinder connection selected before ordering.
