Gas Sampling Tubes
These standard collecting tubes are designed for absorbing specific gases depending on model for quality control testing and other laboratory uses. Gas sampling tubes are designed for the collection and storage of gas samples. Many models feature two stopcocks at either end to allow the flow of gas through the tube, and gas can be extracted by piercing the septum port on the side arm with a syringe. Stopcocks can be either glass or PTFE.
