Dräger Tubes® are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals
Gas detector tubes are one of the classic measurement methods used for gas analysis today. This versatile system can be used in numerous applications in industry, firefighting and disaster management, in the laboratory, for environmental protection and in many other areas.
Our portfolio ranges from short-term tubes for spot measurements for more than 500 different gases, Dräger sampling tubes and systems measuring complex compounds and mixtures of substances, to manual and automatic tube pumps. We also offer an airflow tester and different Dräger-Tubes test sets.
DrägerTubes® are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals. A calibrated 100 ml sample of air is drawn through the tube with the Dräger accuro® bellows pump. If the targeted chemical(s) is present the reagent in the tube changes color and the length of the color change typically indicates the measured concentration. The DrägerTubes® System is the world’s most popular form of gas detection.
Not all detector tubes are created equal! DrägerTubes® with the accuro® pump deliver the most accurate results. Many DrägerTubes® offer a +/- 10% standard deviation on the results. This is a result of
our 70+ years of manufacturing colorimetric tubes and the consistent volume delivered by the bellows pump design. Quality assurance is accomplished by individually calibrating each batch of DrägerTubes®. Then every batch is tested at regular intervals, throughout the two
year shelf life, to guarantee accuracy over the entire life of the tubes.
Reagents used in DrägerTubes® are chosen to provide not only the most accurate, but also most specific results possible. Our use of prelayers on many tubes (like benzene) remove other potential interfering gases (e.g. aromatic hydrocarbons) so you measure only the targeted chemical, getting only the results you want. This design enables you to measure specific gases in a complex ambient background found in the measurement area.
