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
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 Scentroid Link below to see the study!
Nalophan Bag Uses
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 method.
Samples that have high humidity
Not Recommended For
Samples that are processed with a delay exceeding 30 hours
