1/2” Low Flow High Purity Gas Stick

Invatech Engineering’s High Purity Gas Sticks are built and tested to the highest industry standards and are the primary choice of Semiconductor device manufacturers worldwide.

All gas sticks are manufactured in a class 10 cleanroom, packaged, inventoried and available to ship worldwide.

All Invatech High Purity Gas Sticks are tested by a 3rd party onsite QA/QC group for particles, moisture and Helium leak rate. The sticks are dried down, filled with a purified inert gas to 20 psig, double bagged and packaged for inventory.

Invatech Gas Sticks are shipped on our low cost proprietary rail system that protects the gas stick from damage & makes for an easier installation.

All Invatech Gas Sticks are shipped with back mount gauges. This takes up considerably less space than lower mount gauges mounted to the side of the regulator.

Your gas stick will ship out of inventory with the confidence that your tool hook up will go off without a hitch.
