Pico-Cylinder – Breakaway Septum


Pico-Cylinders with Breakaway Septums are the easiest to open on the planet. Our patented septum design is able to be opened consistently, even for life-saving applications where 99.999% reliability is needed.

Picocyl has developed a hermetically sealed cylinder and has proven its leak-free performance with Real Time Aging data exceeding 36 months. For a Pico-Cylinder to be released to customer, it must pass a rigorous multi-stage set of leak testing that has been developed to test products for minimum of 5-year shelf-life. This multi-stage testing regimen ensures that every Pico-Cylinder that leaves our manufacturing facility is leak-free.

Laser Marking
Always looking to push the boundaries of quality further, Picocyl has developed a laser marking system that allows for the verification of the fill-mass for each Pico-Cylinder at any time throughout its lifespan. The laser-marking feature, human readable and QR machine readable, has been proven its legitimacy with Real Time Aging data exceeding 36 months to give you the ultimate confidence.
