What are Tedlar bags?
Tedlar bags are made from a polyvinyl fluoride (PVF) film that is tough, durable, and chemically inert to a
wide range of compounds. Bags used in environmental applications typically have a 2 mil film thickness.
What is the use of Tedlar bags?
Tedlar bags can be used for a variety of applications. Applications include: indoor air sampling,
hazardous waste sites sampling, leaking underground storage tanks, stack sampling, soil gas sampling,
calibration gas blending and preparation of standards, and most other gas sampling needs.
What compounds can be collected in a Tedlar bag?
Tedlar bags are not recommended for use with reactive compounds and compounds that might adhere to
the bags' surface. Remember that the more reactive the compound, the less time it may be kept in the bag
before the sample results begin to be compromised. Generally, holding times of 24 hours are
recommended for sulfur gases, especially hydrogen sulfide and methyl mercaptan, and 72-hour holding
time is recommended for atmospheric gases such as oxygen, nitrogen, carbon monoxide, etc.
Can Tedlar bags be reused?
Yes, it is possible to reuse Tedlar bags for some applications. But we do not typically recommend reusing
bags. You should not reuse the bag after sampling compounds found at ppbv (parts per billion)
concentrations, reactive compounds, or compounds that are known to adhere to the surface of the bag.
The bags must be evacuated and thoroughly cleaned and flushed after each use with purified air or
nitrogen before reuse.
Can Tedlar bags be sent via an air courier?
Yes. But only in pressurized cargo cabins. The contents of the bags will expand when exposed to the lower
pressure conditions reached at cruising altitudes. Therefore, fill the bag to less than 50% of its maximum
volume to give the contents room to expand. Otherwise, the bag may burst during transit.
What is the feature of your Tedlar bags?
All of our stock bags feature an eyelet and our patent-pending single 2-in-1 fittings that combine the valve
and septum into one. You can choose which way you want to use them according to your needs and
preferences. We offer polypropylene, stainless steel, and Teflon fittings.
Can you make tedlar bags of the specific sizes that I require?
Yes, we can. We do offer custom sizes for tedlar bags. Please check with our representatives to make sure
about the sizes before you place an order.
