Airgas® Model 20619 24-Inch Laboratory Gas Drying Tube - Perfect for Chemistry Labs, Scientific Research & Industrial Applications

This molecular sieve drying tube is designed for the removal of excess moisture and heavy hydrocarbons such as pump oils. It may be used in a variety of applications such as compressor delivered gases, electrolytic hydrogen, in-house gas lines or anywhere moisture or oil may be a problem.

This trap may also be used as additional protection on high purity gas systems where even routine cylinder changes may introduce moisture.

The trap consists of a 24" metal tube filled with 1/2 pound of molecular sieve 5A and is capable of reducing water concentrations to less than 0.1 ppm.
