Most people think of welding when they think of argon gas. In fact, argon is a safe, benign gas which can be used to preserve wine, food and historical documents. For some time nitrogen was the ‘go to’ gas when it came to extending the shelf life of packaged goods but scientists have found that argon is actually 4 times more efficient than nitrogen, it is also around 40% denser than air and improves food safety. Thus argon is more effective than nitrogen in keeping food fresher for longer and improving its quality. So how does it work? Gas is used to replace oxygen which not only causes food to oxidise and spoil but allows bacteria to grow. Argon removes the oxygen very efficiently compared to nitrogen as it is denser and is able to more completely fill the spaces around food. Bacteria is starved of oxygen and enzymes that increase the rate of oxidation are inhibited. The use of food grade argon as a preserver does not add anything to the original product, rather it stops it from going bad in a completely safe way. Rent Free Gas is able to supply customers with food grade argon for a multitude of uses including the preservation of food and wine. Our rent free model allows our customers to purchase their own argon cylinder which they will never pay any rent on...ever! The cylinder will come completely full of gas and delivered for free in Sydney, Brisbane and Adelaide. Whenever more gas is needed we will simply come out and replace the empty argon cylinder with a full bottle. If a smaller c size cylinder is all you need we can post it to you anywhere in Australia. Give us a call and let one of our friendly team help you out with your argon gas needs today.
Welding with a nitrogen gas bottle For stainless steel tube welding, a nitrogen gas bottle is a perfect purge gas. You probably require nitrogen for your DIY welding projects or for your nitrogen plastics welding system, but you may not be aware that it has so many other uses. Nitrogen, whose symbol is N or N2, makes up no less than 78% of the Earth's atmosphere. It has no colour, odour, taste or toxicity and it is not flammable. It was officially isolated in the 18th century, but scientists knew about this element – crucial to biological life – long before this. The uses of a nitrogen are endless! You will be amazed at just how many uses a nitrogen gas bottle has. Use this versatile inert gas to superbly inflate tyres, improving tyre life and also minimising the risk of tyre blowouts. Or use your nitrogen to mix it with CO2 for your beer making. In the form of a nitrogen gas bottle, N2 is a seriously handy gas. It can be used in food packaging, wine making, air conditioning and scientific testing – and that's just the start of the possible uses. Nitrogen gas bottles are commonly used in industry for blanketing or purging, which involves the removal of unwanted or unstable gases or compounds, while nitrogen is also used to control the temperature of computer CPUs and for making light bulbs. Ever played with a paintball gun? Nitrogen have been used to supply the power source, even if you may think that carbon dioxide is the obvious choice. A nitrogen gas bottle can also be used for plasma cutting and in combination with argon for a shielding gas. Nitrogen is also used in combination with CO2 in cold brewing coffee. Whatever you need a nitrogen gas bottle for, you can be sure that, here at Rent Free Gas, we have all your requirements covered. Give us a call 0404 677 187 today.
