Specialty gases are just that—our specialty. How do we do it? To start, two industry-leading spec gas labs outfitted with modern technology, ensuring more accurate and more efficient fills. But it’s how we apply our KnowHow with our in-house engineers and chemists who ensure every single tank of our wide range of gases and grades are crafted exactly to your specification. Our Spec Gas Labs Can Deliver: Research-grade gases NIST traceable mixtures Custom certified calibration mixes Anaerobic and aerobic biological mixtures Identical precision fills multiple cylinders simultaneously PS calibration mixes EPA Protocol Industrial hygiene mixes Specialty gas equipment Our Labs are Positioned to Serve You: Built to serve our customers, we have two labs; one in Memphis, Tennessee, and another in Atlanta, Georgia. Both are ISO/IEC 17025:2017 accredited, which means our standards of precision and consistency are top-tier. (We won’t ship a cylinder if it’s not perfect.) Having two labs also delivers an added sense of security knowing that your gas supply always has a backup.
