Tedlar® Gas Sampling Bag Description
Tedlar®PVF Gas Sampling Bag is made of polyvinyl fluoride (PVF) film produced by Dupont USA, film thickness is about 0.05 mm. Our PVF gas sampling bags are made of 2mil DuPont's Tedlar® film. 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.
Tedlar® Gas Sampling Bag Features
Excellent chemical resistance, corrosion resistance, organic solvent resistance, and low adsorption.High tensile strength
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 Teflon 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.
Standard Tedlar Gas Sampling Bag Sizes
0.5L, 1L, 2L, 3L, 4L, 5L, 8L, 10L, 15L, 20L, 30L, 40L～6000L or customized size.
Tedlar® Gas Sampling Bag Applications
Tedlar® PVF film is strong, durable, and considered chemically inert to a wide range of compounds. Tedlar gas sampling bag can be used in high precsion PPM level analysis sampling, can sample and save all kinds of corrosive gas and liquid samples, and used to solid VOCs residual detection.
Tedlar® Gas Sampling Bag Operating guide
1. 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.
2. Operating temperature: Working temperatures should be -60°C to +100°C for PTFE connector and -20°C to +80°C for PC stopcock valve .
3. Storage and use: Keep away from flame and high temperature when filling and storage. Avoid contacting sharp stuff.
4. Gas exchanging: Before use, flush sampling bags three times with the gas you want to fill.
5. 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.
