Fill pressure may be reduced whe supplying heavy hydrocarbons like Hexane and Pentane to ensure they are supplied in a gaseous form and do not liquify.

The gas price per litre is usually less in a bigger cylinder, so upsizing is a more economical way to purchase gas, providing you will use all the gas before it expires. With the compact refillable cylinders from Analysair there are more opportunities to upsize with the larger size fitting in a carry case designed for a smaller size.

Non-reactive gas mixtures are usually available in stock in 100L cylinders, as this is the most popular and one of the most economical sizes.
