Good quality Teflon® FEP Gas Sampling Bags for sales
Dear Judy, It’s a very memorable visit to your factory. Thank you very much for your support and helpful and taking care. Nice to work with you.

—— Chumsin from Thailand

Hi Judy, Thanks again for all your assistance with our order. I shall make sure that we contact you for another quote in a short time.

—— Barry from UK

Hello Judy we received the order this morning, that is a very good delivery time for shipping... Regards

—— Jean from Canada

Hi Judy, I got the bags yesterday, they look nice! Thank you for your nice support and we will make bulk order next week... Very Very nice label!

—— Saowa from Thailand

Hi Judy, yes, these bags worked well and can be reused. Our research work is over now, we thought that the gas only stored for 5 to 6 days in these bags but we stored the gas more than 20 days still the gas composition was same...... Very good! (Feedback about the New Devex bags.)

Devex gas sampling bag compared to Aluminium-foil(multi-layer) gas sampling bag is higher performance replacement. Devex film is developed by HedeTech Co., Ltd. specifically for making high quality gas sampling bags. It is composed of total 11 layer films (PET, PA, Aluminum, PE, etc) with thickness 120-140um.

 

Multi-Layer Foil
Ideal for sampling and storing H2S, and for low molecular weight compounds such as Methane, CO/CO2, Hydrogen, and inert gases which are not stable in Tedlar, ALTEF, or FEP. Water- and vapour-proof, these flexible bags protect light sensitive compounds. Bags are available with several fitting and valve options. They provide up to five day sample stability with minimal absorption.

 

Features:

  • composed of total 11 layer films

  • superb strength and low permeability and high barrier property and low VOCs precipitated amount

  • excellent chemical inertness and stability

  • low price and wide range of applications

  • widely used in petrochemical industry, environmental protection and scientific research institutes

 

We offer the Devex Gas Sampling Bag Sizes from 50ml to 6000L or customized size.

Select from a variety of sizes to suit your needs.

Applications:

  • Devex gas sampling bag can fill the gas being of stable chemical properties, such as: pyrolysis gas, natural gas, coal bed gas, smoke dust gas, ambient atmosphere,technological process reaction gas.It is widely used in petrochemical industry and environmental monitor etc.for gas sampling and save. Devex gas sampling bag can ensure that the low concentration (PPM) component is constant for 1-3 month.

  • Devex gas sampling bag can be used in sampling and detection for non-methane hydrocarbon.

  • Devex gas sampling bag can fill low level of hydrogen(H2), oxyen(O2), nitrogen(N2), argon(Ar), methane(CH4), carbonic oxide(CO), carbonic dioxide(CO2).

  • Devex gas sampling bag is not recommended to use for the gas with high chemical, corrosivity and strong oxidizing property such as: hydrogen sulfide, nitrogen oxides, strong basicity gas and halogens gas or low content component ppb level.

  • Devex gas sampling bag apply to lucifuge sampling for photosensitive gas.

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.
