The X56L-4MCG Stabilizer-brand canisters are used for convenient and reliable collection of ambient air samples. These high purity, passivated, stainless steel canisters are designed to maintain the integrity and stability of the sample while it is being transported to a laboratory, and while it is being analyzed. Common uses include the sampling of volatile organic compounds in air according to EPA Methods TO-14A and TO-15. Stabilizer canisters can also be used to prepare and store low-pressure, nonhazardous calibration mixtures.

Using air sampling canisters, Aerosphere and other LabCommerce canisters are purged and evacuated to approximately 2 millitorr with a vacuum pump. Sampling may be regulated with external components that control flow rate such as a critical orifice-containing flow controller. For time-integrated sampling and for collecting pressurized air samples, LabCommerce manufactures the MCS series canister samplers. Available as either portable or rack-mountable units, the systems include sampling pump timers and flow controls for self-contained precision air sampling.

WARNING: Stabilizer canisters should only be used with pumping systems in which the pressure is controlled to no more than 40 psia. LabCommerce canisters (and air sampling canisters in general) are designed for pressures not exceeding 41 psia. Any pressure above 41 psia is considered a compressed gas per U.S. Code of Federal Regulations 49 CFR, Subpart D, 173.115(b) and must be stored in appropriately designed cylinders. This same regulation also prohibits LabCommerce canisters (and air sampling canisters in general) from being used with flammable, poisonous or liquefied gas.
