PTFE Sampling bags
Easy Air Sampling Solutions
Scentroid is the only manufacturer offering PTFE sampling bags, the only accepted material for all standards. Much more resistant to contamination, Scentroid’s PTFE Sampling Bags have a longer holding time than Tedlar 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.
The Best Sampling Bags in the Market: Tried and Tested
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.” Click on the link below to see our post!

Results are in: Scentroid Exclusive PTFE Sampling Bag is Superior!
Completely Odourless
High density PTFE Sampling Bags have zero background odour giving you much more accurate measurements
Maximum Sample Retention
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
Cost Effective
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
- 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.
- Excellent stability for petrochemical products such as benzene.
- Low sample absorption.
- Zero background odour allows for ambient sampling.
- UV protection helps preserve samples during transportation.
- Easy to clean and reuse (typical lifespan is 30 samples).
- Stocked in a variety of sizes; custom bags available.
- Recommended for a sample processed after a long delay - 12 to 30 hours
-
Excellent stability for most compounds including VOCs, sulfur compounds, including hydrogen sulfide
- Excellent stability for carbon monoxide, carbon dioxide, methane, and sulfur hexafluoride
- Choice of fittings to match bag size and application include both compression and 2-in-1 valve/septum fittings in a variety of materials including PTFE, stainless steel, PTFE coated Nylon, and Polypropylene.
- Bags available for EPA TCLP method.
- Perfect for samples with high VOCs and H2S
- Samples that have any petrochemical products such as benzene
- Samples with low odour threshold as it will not contaminate sample
- Samples that have high humidity
PTFE Sampling Bags Not Recommended for:
- Samples that are processed with a delay exceeding 30 hours
Scentroid Fittings for PTFE Sampling Bags:
2 in 1 Polypropylene
On/Off valve function with replaceable septum in a single unit. Quick, easy opening and closing of valve. Less than one half turn opens/closes the valve. These fittings fit 4/1” & 6 mm tubing
2 IN 1 PTFE FITTING
The combination fitting and septum is made of pure PTFE and offers high corrosion resistance. The fittings are light weight and therefore provide an excellent choice for PTFE sample bags
PTFE COATED NYLON
These fitting offer zero resistance with sample flow and therefore are the ideal choice for large sample bags. They also allow attaching tubing or syringe sample extraction by changing caps
STAINLESS STEEL FITTING
These all stainless steel fittings are used only on Scentroid stainless bags. This type of fitting is highly resistant to corrosive materials and can be used in high temperature sampling
