A CO2 cartridge typically lasts for about 1-2 hours, depending on the size and usage.
To use a CO2 cartridge effectively, first ensure the cartridge is compatible with your device. Then, insert the cartridge into the designated compartment and tighten securely. Follow the manufacturer's instructions for releasing the CO2 gas, typically by pressing a button or lever. Be sure to handle the cartridge carefully and dispose of it properly after use.

The duration of a CO2 cartridge in a specific device or application depends on factors such as the size of the cartridge, the frequency of use, and the amount of CO2 required for each use. It is recommended to refer to the manufacturer's guidelines for more accurate information on the expected lifespan of a CO2 cartridge in a particular device.
To use a CO2 cartridge to make whipped cream, you can attach the cartridge to a whipped cream dispenser, add heavy cream and sweetener to the dispenser, then charge it with the CO2 cartridge. Shake the dispenser well, and dispense the whipped cream onto your dessert.
