Challenge: Designing a cylinder that is more reliable, energy efficient & easy to use.

innovation overview

Our patented breakaway septum design differentiates the Pico-cylinder from every other pressurized gas cylinder on the market. Energy efficient, precise and reliable, our breakaway septum ensures you get exactly how much gas you need, when you need it.

Functionality

The patented breakaway septum design differentiates the Pico-cylinder from every other gas cylinder on the market. Whereas legacy industrial grade gas cylinders rely on a sharp puncture pin to pierce the ductile septum, the Pico-cylinder relies on the material properties of the cylinder Cap and the patented septum geometry to provide a consistent low force puncture. These features allow Pico-cylinders to be punctured with blunt, non-geometrically critical Opener Pins. Further, other sharp puncture pins generally require modifications to create flow channels to provide an adequate path for gas escapement due to the nature of the septum’s plasticity. Because of the material selection, cylinder neck design, and cap design, the Opener Pin preferentially tears the perimeter of the septum to “open the hatch” in a controlled manner with a 4x reduction in stroke and a 10x reduction in energy. The novel septum geometry results in a large annular gap encompassing the Opener Pin allowing for rapid and unobstructed gas egress from the cylinder.
