Tedlar® PVF Air/Gas Sampling Bags with PTFE dual-valve solid VOCs
residual detection TDL32_2000L Dupont Film gas bag
Description:
Tedlar®PVF Gas Sampling Bags are constructed of 2-mil
thick Tedlar® with solid seam to keep gases contained.Tedlar® film
is polyvinyl fluoride (PVF) film produced by DUPONT USA.
In the late 1970s SKC USA used Tedlar film to make
gas sampling bags for the first time, Tedlar® PVF is strong,
durable, and considered chemically inert to a wide range of
compounds. Tedlar gas sampling bag can be used in high precision
PPM level analysis sampling, can sample and save all kinds of
corrosive gas and liquid samples, the heat-resistance temperature
of Tedlar is 150℃~170℃. For over 30 years, the SKC USA constantly
promoted Tedlar to make users all around the world generally
accepted Tedlar gas sampling bags and approved by USA EPA. At
present Tedlar gas sampling bags are also recommended in domestic.
In recent years, country environmental regulations
are increasingly strict, detection business of testing institutions
detecting organic volatile residue for cars, household goods and
other products of civilian use is also increasing. Our company can
customize large size Tedlar Sampling Bags, which can reach 3000MM,
volume 6000L, trilateral edge sealing side and one side sealed with
straight rod clamp(3m)(as shown below), used to solid VOCs residual
detection. Such as automobile engine, automotive parts, household
items pollution detection.
Tedlar gas sampling bags are accredited by regulatory
agencies in different countries and widely used indoor air
sampling, waste processing yard gas sampling, soil sampling and
other environmental protection application. Our Tedlar sampling
bags come with renovated, patented valves. The materials of the
valves are Polycarbonate(PC) or Polytetrafluoroethylene(PTFE) or
Polypropylene(PP); Depending on inlet orientation, there are two
types of valves: one type is that the inlet in vertical to the
film, the other one type is the inlet horizontal to the film, both
valves have the same functionalities: has on/off function; has a
sample cap with septum inside for syringe sampling purpose, both
valves are easy to use. One advantage of horizontal valve(side
opening) is touse less storage space.
- Low gas permeation levels
- High tensile strength
- Continuous temperature range from –98°F to 225°F
- Unaffected by the chemical components of gases commonly sampled,
like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and
mercaptans
Standard Tedlar Gas Sampling Bag Sizes: 0.5L, 1L, 2L, 3L, 4L, 5L,
8L, 10L, 15L, 20L, 30L, 40L~6000L or customized size.
Select from a variety of sizes to suit your needs.
Features:
- Excellent chemical resistance, corrosion resistance, organic
solvent resistance, and low adsorption.
- The water vapor osmotic quantity of Tedlar film is
13g/m2.24h.0.1MPa; and oxygen osmotic quantity is
114cc/m2.24h.0.1MPa (the data is measured value not guarantee
value).
- Gas barrier property of Tedlar PVF film is superior to FEP film.
- Less permeable than FEP, Kynar PVDF and Fluode.
- Bags resist puncture in the field.
- Less expensive than FEP and Kynar PVDF film.
- Recommended in many EPA testing methods.

Operating guide:
- Inflation pressure: Avoid filling pressure higher than 6000Pa. Fill
gas until the bag is fully expanded, however, it is not so tense
when you press it using your finger.
- Operating temperature: Working temperatures should be -60°C to
+150°C for PTFE connector and -20°C to +80°C for PC stopcock valve
.
- Storage and use: Keep away from flame and high temperature when
filling and storage. Avoid contacting sharp stuff.
- Gas exchanging: Before use, flush sampling bags three times with
the gas you want to fill.
- Needle sampling: When using a needle to draw gas from highly
elastic septum, squeeze the septum with fingers in order to restore
the sealing property after pulling out the needle.
Precautions:
- The sample gas in sampling bag to save time should not be too long,
specific saving time depend on detection limit of experimental
analysis requirement,gas component species,temperature and
humidity,pressure, etc: generally, for pure inert gas, sampling bag
can be used as a temporary storage container and recommended
storage time less than 72 hours; for standard gas,flue gas,ambient
atmosphere, recommended storage time less than 24 hours.
- The gas sampling bag should be cleaned repeatedly replacement if it
is reused. Suggest the same sample bag collecting samples of the
same kind gas, don't mix.
- High purity nitrogen gas heating replacement can reduce the
interference of organic deposition.
- Avoid filling pressure higher than 6000Pa, fill gas until the bag
is fully expanded, however, it is not so tense when you press it
using your finger.The overpressure filling can cause gas sampling
bag burst damage.
- When sampling and cleaning, please do not exceed 80% of the
calibration volume, take 1L sampling bag for example, suggest
sampling volume is less than 0.8 L.
