Nightline™ with Ted Koppel featured our gas control panel, which uses Circle-Seal needle valves. In the late summer of 2012, our anti-torque ring designs landed on Mars with the Mars Science Laboratory that deployed the Curiosity rover. Our patented minimum dead volume fitting, which is used in approximately 50% of the world's Integrated Gas Systems designs used to supply ultra-high purity gases in the semi-conductor industry. Additionally, a description of our recycle program appeared in Applied Materials magazine.
