Calibration Gas

The Portagreen range of calibration gas cylinders enable businesses to reduce their carbon footprint and cut costs while demonstrating a commitment to the environment.

The highlights of the new Portagreen range speak for themselves. They are refillable, compact, made from the highest quality, tested for the lowest failure rate and longest shelf life and totally recyclable. This means:

Refillable The Portagreen range of cylinders are made from a unique design, enabling re-use of traditionally disposable cylinders. Recycling reduces the environmental cost of landfill.

Compact With the ability to carry twice as much gas, or half the size of the old style cylinders, the Portagreen range is essential for technicians with limited vehicle space. For example, a 58L Portagreen cylinder will fit in a case designed for the old style 34L cylinder, while the 100L and 116L Portagreen cylinders are of similar size to the old 58 litre cylinders.

Lowest Failure Rate Each cylinder is individually QA tested and fully traceable with N.I.S.T. certification. Rigorous QA procedures and testing has enabled the manufacturer to sustain a return rate of less than 0.3% for several years.

Highest Quality Manufactured by Portagas, an innovator leading the calibration gas market for the last ten years. Now with ISO 17025 approval you can be confident that you will receive gas with the highest accuracy levels!

Longest Shelf Life Enhanced production procedures reliably deliver reactive gases with the longest shelf life. Currently 36 months for non-reactive gases and up to 24 months for many reactive gases including the quad mix with H2S.

Recyclable Every Portagreen cylinder is supplied with the unique “Strip & Ship” program, which includes a reply paid consignment note and packaging tube for easy return shipment of the empty cylinder. Once the empty cylinder declaration has been signed, the cylinder can be packed in the tube and shipped for recycling at no additional cost. This simple program will help your business demonstrate their initiatives in recycling and reduce the time and money associated with the disposal of “dangerous goods.” (This return program is limited to gas mixtures classified as dangerous goods class 2.2.)

Return Program

Scientific Gas Australia and Australia Post have partnered to deliver the first return program for small portable gas cylinders. This “Strip and ship” recycle program uses Australia Post’s “Reply Paid” service enabling economical return of the cylinders to Portagas for refilling.

The Strip and Ship program enables gas users to choose a “green” product to:

  • Demonstrate participation in an environmental program.
  • Safely dispose of pressurised cylinders without having to cut or drill.
  • Reduce landfill.

Australia Post has limited participation of the strip and ship program to within Australia and vented (empty) cylinders formerly of dangerous goods class 2.2 only.

The approved reply paid packaging label must be in colour and clearly visible.

The standard Australia Post Dangerous Goods declaration has been used and must be signed. Australia Post do not classify empty cylinders formerly of class 2.2 as dangerous goods, so it is ok to sign this declaration if the cylinder class was 2.2 and the cylinder has been verified as being empty.

There must be ventilation holes in the packaging.

The cap must be attached to the packing tube with tape.

The maximum weight handled by the reply paid service is 20 KG. There is no need to pack multiple cylinders into a box.

Cylinders can be dropped into the nearest mailbox, delivered to the nearest post office or picked up with a messenger post service.

Please support the environment by participating in this scheme!
