In a busy pub or cocktail bar, consistency is king. Customers expect their favourite drink to taste the same every time, and that's where reliable consumables make all the difference. These iSi cartridges are the gold standard—they’re not fancy, but they are incredibly dependable, delivering a perfect fizz that never tastes metallic. They are the unsung heroes of a great beverage programme.

- Con: Being disposable, you need to manage your stock and recycling process well.
Case Study: Real Business, Real Results
"The Copper Pot," a popular gastropub in Cardiff, was looking to reduce its glass waste and cut the high cost of buying bottled sparkling water and mixers. They invested in two commercial soda siphons and made the switch to using iSi GH056 CO2 cartridges for all their carbonation needs.
"The consistency is fantastic. We can now make our own artisanal tonic waters and sodas, which has given our drinks menu a real point of difference. The savings are just a bonus!"
Samuel Jones – Bar Manager
The result was a 30% reduction in their monthly mixer costs and a dramatic decrease in the volume of glass going into their recycling bins.
Installation and Maintenance Guide
Setting It Up
- Always ensure your soda siphon is clean and has been rinsed with cold water before use.
- Insert one CO2 cartridge into the charger holder, narrow end first.
- Firmly screw the holder onto the siphon head until you hear a distinct hiss—this means the gas has been released.
- Give the siphon a good shake (at least 5-6 times) to help the CO2 dissolve into the water.
Keeping It Going
- Store unused cartridges in a cool, dry place, away from direct sunlight or heat sources.
- Always dispense all pressure from the siphon before attempting to unscrew the charger holder.
- The steel cartridges are recyclable, so please dispose of them with your metal recycling.
- Regularly check the rubber seals on your soda siphon to ensure a tight fit and prevent gas from escaping.
Frequently Asked Questions
Q: Are these CO2 charger bulbs refillable?
A: No, for safety and hygiene reasons, these are single-use, non-refillable cartridges. They should be recycled after use.
Q: Can I use these for my cream whipper?
A: No, absolutely not. These contain CO2 for carbonating drinks. You need N2O (Nitrous Oxide) cartridges for whipping cream.
Q: How much water will one cartridge carbonate?
A: One 8.4g CO2 cartridge is designed to fully carbonate up to 1 litre of water in a compatible soda siphon.
Q: Will these fit any brand of soda siphon?
A: They are designed for a universal fitting but are guaranteed to work perfectly with iSi models CE341 and CR708. We recommend checking your device's manual.
Q: Is there an expiry date on these soda syphon cartridges?
A: The cartridges themselves do not expire, as the CO2 gas inside is inert. However, it's always best to use older stock first.
Q: How should I store the box of cartridges?
A: Keep them in a cool, dry place away from direct heat or sunlight, like a stockroom or under-counter cupboard.
Q: Are they safe to carry or transport?
A: Yes, they are perfectly safe for transport. The steel casing is very strong, but they should not be exposed to extreme temperatures.
Q: How do I know when the cartridge is empty?
A: You will hear the gas release when you first screw it in. Once that happens, the gas is in the siphon, and the cartridge is empty and can be removed after the siphon is depressurised.
The iSi Standard: More Than Just Bubbles
When you buy iSi, you're investing in over 50 years of Austrian precision engineering and a reputation built on absolute reliability. As the global market leader in pressurised gas systems for the kitchen and bar, iSi represents trust. For a busy business, this isn't a small thing. It means every one of these soda siphon CO2 charger bulbs is manufactured to the same exacting standards, filled with pure, clean-tasting CO2, and guaranteed to perform. This consistency protects your expensive siphon from damage caused by poorly made, ill-fitting cartridges and ensures the drink you serve a customer in June is identical to the one they loved in January. It's this long-term operational peace of mind—knowing your tools will simply work, service after service—that defines the iSi advantage.
Explore more from ISIWhy 'Efficient Design' Means a Better-Tasting Drink
You might think all CO2 chargers are the same, but the 'efficient design' of these iSi bulbs makes a real difference to your final product. It's not just about pushing gas into water; it's about how it's done. These bulbs are engineered to release their CO2 at a precise pressure and rate, allowing the gas to dissolve fully and evenly into the liquid.
Think of it like the difference between hastily stirring sugar into iced tea versus letting it dissolve slowly in hot tea first. One gives you a gritty, uneven result, while the other is perfectly smooth. The iSi design creates finer, more integrated bubbles. This results in a smoother 'mouthfeel' and a fizz that lasts much longer in the glass, rather than a harsh, aggressive sparkle that disappears in seconds. It’s a small detail that leads to a much more premium drinking experience.
