PTFE Bags

PTFE Bags

Scentroid is the only manufacturer offering PTFE sampling bags. These bags have a much higher resistance to contamination and Scentroid’s PTFE Sampling Bags have a longer holding time than Tedlar bags. They are also the only accepted bag material for all standards. PTFE Sampling bags are extremely resistant to contamination and therefore can be easily cleaned and reused. They have been approved by the Ministry of the Environment in Ontario and almost every other jurisdiction around the world.
