iSi North America CO2 Soda Siphon Chargers — 30‑Pack 8g Cartridges, Leak‑Proof Recyclable Steel

These are 30 recyclable, 8‑gram CO2 cartridges made for iSi soda siphons to carbonate water and homemade soda quickly and reliably.

iSi CO2 Soda Siphon Chargers come as a convenient 30‑cartridge set in steel casings, each holding one eight‑gram charge of carbon dioxide. They are made for use with iSi soda siphons and similar compatible devices, offer a leak‑proof design with no expiration date, and let you carbonate water or flavored mixes at home without complicated equipment. The chargers are disposable and recyclable, simplifying storage and handling for frequent home use.

How do these CO2 chargers work with my iSi soda siphon?

The chargers are inserted into the charger holder of an iSi soda siphon and punctured to release CO2 into the siphon’s pressure chamber. The gas dissolves into the liquid under pressure, creating carbonation when dispensed, and each 8‑gram cartridge provides a single full charge for one fill of a standard siphon.

• Eight grams of CO2 per cartridge for one full siphon fill
• Steel casing designed to fit iSi charger holders
• Leak‑proof construction to prevent accidental gas loss
• No expiration date—store extras for whenever you need them

Are these cartridges safe and easy to store?

Yes. Each cartridge is sealed in a recyclable steel shell to keep the pressurized gas contained until use. Because there’s no shelf‑life limit, you can keep a spare supply on hand; store them in a cool, dry place away from direct heat or flames to maintain safety.

• Recyclable steel casing reduces waste impact
• Leak‑proof seal lowers risk during storage
• Compact size makes them easy to stack or tuck into cabinets
• Keep away from heat sources and open flames for safety

What drinks can I make with iSi CO2 Soda Siphon Chargers?

These chargers carbonate plain water, allowing you to create sparkling water or to use as a base for flavored sodas. You can also carbonate cocktail mixers, iced tea, fruit syrups, and other non‑alcoholic beverages—just follow your siphon’s instructions for safe filling levels and temperature limits.

• Sparkling water as a neutral base for syrups or juices
• Homemade sodas using fruit concentrates or herbs
• Carbonated mixers for mocktails and cocktails (follow device guidance)
• Control fizz by chilling liquid before charging for stronger carbonation

How many cartridges should I expect to use and when should I replace them?

Each 8‑gram cartridge supplies one charge for a standard iSi soda siphon fill. If you carbonate multiple bottles or larger fills, plan quantity accordingly—this 30‑pack provides thirty single fills. Replace a cartridge whenever your siphon’s performance indicates low pressure or if a cartridge has been punctured.

• One cartridge per standard siphon fill—30 charges total in the set
• Monitor fizz and pressure; replace when charge weakens
• Keep spare cartridges accessible for entertaining or frequent use
• Recycle used steel casings where local facilities accept them

Who is this for? Home cooks, beverage enthusiasts, and anyone who enjoys freshly carbonated drinks will find these iSi CO2 Soda Siphon Chargers useful. They suit households that prefer making custom sodas, bartenders testing non‑alcoholic mixers, and small cafés or food trucks that use iSi soda siphons for quick carbonation. Because the cartridges are compact, leak‑proof, and have no expiration date, they’re ideal for regular at‑home use or as a reliable backup supply for events.
