Draeger Tubes Gas Test Tubes

Draeger Gas Test Tubes, also known as Draeger-Tubes® are used to detect an array of different gases in an environment. The gas test tubes are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals. The test collects a calibrated 100ml sample of air, the air is drawn through the tube with a Draeger Accuro® bellows pump. If the targeted chemical or chemicals are present in the environment, the reagent in the tube will change color, the length of the color change typically indicates the measured concentration. Dräger-Tubes are an easy to use and cost effective way to measure toxic gases and vapors in the workplace. More than 200 different Dräger-Tubes are available to accurately make spot measurements for over 500 gases and vapors. Dräger-Tubes are used in conjunction with either a manual or automatic sampling pump using individual Dräger-Tubes or special 5 tube sets for simultaneous measurement. Dräger Pumps and short-term Dräger-Tubes® are not interchangeable with other manufacturers' pumps and detector tubes. Simply select the appropriate Draeger-Tube® according to the chemical hazard to be tested and the required measuring range. The Draeger Tube Handbook is a good source for application and specific details related to gas measurement, air flow currents and how to correctly use the tube and pump system.
