The Nafion Tubing for Gas Sampling Sensors is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.


  • Removes water vapor from gas samples
  • Does not affect gas samples
  • Used for capnography, measuring ETCO2


  • 24 in. (61cm) long
  • Inside Diameter (IN): Minimum 0.054 - Maximum 0.066
  • Outside Diameter (IN): Minimum 0.065 - Maximum 0.079
  • Wall Thickness (IN): 0.006
  • Standard female and male Luer-Lok connectors
  • Can be sterilized or cleaned between uses
  • Maximum operating temperature is 120 c
  • Latex free


Caution: While Nafion can remove virtually any humidity from a gas sample, filling it with liquid water will result in the loss of the ability to remove water vapor. Normally, drying the tubing completely will restore functionality.

Because Nafion uses sulfur ions to selectively transport water molecules out of the tubing, it is not gas permeable. Therefore, Nafion can be used successfully to dry virtually any gas.  Naphion is also recommended to be used with water traps & hydrophobic filters that are included with all sampling devices.  Install the tubing after the filters for optimum performance & protection of the sensor.

Nafion Tubing for Gas Sampling

Nafion Tubing for Gas Sampling this revelation in drying small amounts of gas in front of CO2 and O2 sensors is very good in our applications. Please forgive me for mistakes, I do not speak English, I use google translator.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
