Non-Refillable Cylinders, The Convenient and Cost-Efficient Way to Handle Calibration Gas Mixtures.

These smaller-sized, lightweight cylinders require no deposite or monthly rental charge. They are easier to handle and use very little space. They also eliminate over-purchasing when only small quantities are necessary. For greater confidence, all stock calibration gas mixtures are analyzed against NIST traceable standards where available. Ask your NorLab representative for a part number cross-reference sheet to help you match your instrument manufacturer's part number.

                                               Nonreactive Gases                                                                                                  

The 103 liter cylinder is recommended for nonreactive gas mixtures and pure gases such as Argon, Nitrogen, Nitrous Oxide, and Helium. This cylinder combines a convenient size with enough capacity to handle even your most rigorous calibration requirements.

Gas mixtures are certified to an analytical accuracy as follows:                                 

10 ppm to 49 ppm ±5% of the minor components
50 ppm to 50% ±2% of the minor components                         

NOTE: Top pressure and volume will be reduced if concentration is greater than: Heptane 750 ppm(7.1% LEL)-Toluene 700 ppm(5.5%LEL)-Hexane .2%(17% LEL)-Pentane .56%(40% LEL)

                         Medical and Gas Mixtures For Special Applications

New offerings of laser, blood gas, and lung diffusion medical mixtures give NorLab an added dimension few other suppliers offer. This medical "E" style, 550 liter, 2200 PSIG, non-returnable cylinder, valved with the appropriate CGA fitting completes the package. This cylinder is recommended where larger amounts of non-reactive pure gases or mixtures are required without sacrificing portablity. Contact NorLab for other mixtures not listed.

Reactive Gases

The 58 liter cylinder is manufactured of aluminum and is recommended for mixtures that are not stable in steel cylinders. These include Hydrogen Sulfide, Sulfur Dioxide, Nitrogen Dioxide, Nitric Oxide and Ammonia. Gas mixtures in Nitrogen are certified to an analytical accuracy as follows: 5-24ppm ±10% of the minor components 25-300 ppm ±5% of the minor components

NOTE:Gas mixtures for reactive gases with air are certified to an analytical accuracy of ±10% of the minor components.

                                 Economy Plus Quality

The 17 liter cylinder is recommended for gas mixtures where only a small quantity is required. This includes LEL (Lower Explosive Limit), Carbon Monoxide, and other nonreactive mixtures.
Gas mixtures are certified to an analytical accuracy as follows: 10 ppm to 49 ppm ±5% of the minor component 50 ppm to 50% ±2% of the minor component
