Available practically everywhere.

Portagreen cylinders are Portagas’ line of recyclable and sustainable calibration gas cylinders. Our standard Portagreen cylinders are available in five sizes and our MegaCal™ Portagreencylinders in three sizes. Our Portagreen cylinders are more compact than standard calibration gas cylinders and provide the capacity you need in more portable sizes.

These ISO 7866 globally approved cylinders are available practically anywhere and when combined with our patented Strip & Ship™ return program, you can use Portagas’ high-quality calibration gases without the concerns of waste disposal.

Portagas manufacturing facilities are ISO 9001:2015 certified as well as ISO 17025:2017 and ISO 17034:2016 accredited. We package high-quality calibration standard gases in rugged, portable cylinders designed to go anywhere your calibration process requires.

Our calibration gases have an extremely low return rate and our proprietary fill technologies support a long shelf life. Each cylinder carries a unique serial number and is issued a Certification of Analysis demonstrating traceability to N.I.S.T.
