Scentroid - Model Sampling Bags -PTFE Sampling Bags
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.
A recent independent study from the Journal of Environmental Quality has concluded that our exclusive PTFE Sampling Bag is superior to any other sample bag, including Tedlar bags. “Scentroid’s PTFE bags were found superior for storing the considered odorants from pig production, especially for 4‐methylphenol, which was almost completely lost on introduction to Nalophan and Tedlar bags.”
Benefits of PTFE Material
- Ultra-pure PTFE film with exceptional sample preservation
- PTFE density of 2.2 g per cubic centimeter is twice as high as Tedlar allowing for much longer sample preservation
- Low sample absorption & Odourless
- Zero background odour allows for ambient sampling
- Bags available for EPA TCLP method
- Samples with low odour threshold as it will not contaminate sample
Chemical for Sampling
- Excellent stability for petrochemical products such as benzene
- UV protection helps preserve samples during transportation
- Excellent stability for most compounds including VOCs, sulfur compounds, including hydrogen sulfide
- Excellent stability for carbon monoxide, carbon dioxide, methane, and sulfur hexafluoride
- Samples that have high humidity
Maximum Sample Retention & Cost Effective
PTFE provides the highest sample retention of any media. Scientific studies have shown an improvement in 24 hours of up to 600% more in sample retention when compared to Tedlar. PTFE sample bags are reusable, making them a cost effective option. Laboratories using the SP20 Heated Purger routinely reuse PTFE sample bags up to 30 times.
