Pico-Cylinder – Valve-Release


The Gas Powered Valve Release Pico-Cylinder was the first Pico-Cylinder we designed. This ground-breaking product enables the cylinder to be welded shut first and then filled with the gas. For years small cylinder product designers and engineers were stumped as contained gases reacted when sealed using a traditional welding process.  No more.  Our patented valve release design ensures superior performance and quality to deliver the necessary amount and purity of gas.  This product is compatible with implant grade gases.

Picocyl has developed a hermetically sealed cylinder and a multi-stage set of leak checks to ensure that every Pico-Cylinder that leave our manufacturing facility does not leak.

Laser Marking
Always looking to push the boundaries further, we developed a laser marking system that allows you to verify the mass of the cylinder for the life of the product, giving you the ultimate confidence.
