Product description
Drager Orsa 5, Passive Sampling Tube
Drager passive sampling tube, Orsa (5 pieces).
NOTE: This product has a shelf life of 2 years.
Advice for sample-taking
Air sampling is carried out in the previously determined measuring period which should be documented. After sampletaking the sampling tube is sent to the laboratory for analysis in the tightly sealed glass bottle.
Note concerning the analysis
The enriched volatile organic compounds are analysed in accordance with the procedures recommended by BGIA, DFG, NIOSH, OSHA and HSE.
