Nitrous Oxide Canisters: What You Need to Know Before Buying
Nov
Introduction
Whether you’re running a café, catering business, or love experimenting in the kitchen, nitrous oxide canisters are an essential part of making smooth, stable whipped cream.
But before you click “buy now,” it’s important to understand what they are, how they work, and the UK laws surrounding their use.
This guide will help you make an informed, safe, and legal purchase — with trusted options available at CreamChargers.co.uk.
What Are Nitrous Oxide Canisters?
Nitrous oxide (N₂O) canisters — also known as cream chargers — are small steel cylinders filled with pressurized gas used for whipping cream and foams.
When attached to a cream whipper, they infuse the gas into cream, creating a light, airy texture in seconds.
Each canister usually holds 8 grams of food-grade nitrous oxide, perfect for both home and professional kitchens.

How Nitrous Oxide Works in Whipped Cream
When you load a canister into a dispenser:
- The N₂O gas mixes with the cream under pressure.
- When you press the lever, the cream is released, expanding instantly into a fluffy, whipped texture.
- The result is stable whipped cream that holds its shape longer than hand-whipped versions.
For catering professionals, N₂O tanks provide the same results on a larger scale — see our N₂O Tanks Collection.
Which Size Nitrous Oxide Canister Do You Need? 8g vs 580g vs 640g
Nitrous oxide canisters come in three main sizes. Choosing the right one depends on how often you use them and the volume of cream you need to whip. Here’s a quick breakdown:
| Size | Best For | Servings (approx.) | Price Per Serving | Example Brands |
|---|---|---|---|---|
| 8g charger | Home use, occasional baking, small cafés | ~0.5 litre of whipped cream per charger | Lowest upfront cost; moderate per-use cost | Mosa, iSi, Liss |
| 580g tank | Busy restaurants, caterers, high-volume kitchens | Equivalent to ~72 standard 8g chargers | Much lower cost per serving vs 8g | FastGas, GoldWhip |
| 640g tank | Professional catering, large-scale food production | Equivalent to ~80 standard 8g chargers | Best value per litre of N₂O | FastGas 640g |
Not sure which to choose? If you use cream chargers daily or run a catering operation, a 580g or 640g N₂O tank will save you significant money over time. For home bakers using a dispenser once or twice a week, a pack of 8g chargers is the most practical option.

Frequently Asked Questions About Nitrous Oxide Canisters
Are nitrous oxide canisters legal in the UK?
Yes. Nitrous oxide canisters sold for culinary use are completely legal in the UK. They are used professionally in kitchens, cafés, and restaurants to make whipped cream and infusions. However, recreational inhalation of N₂O is illegal under the Psychoactive Substances Act 2016. All products sold at CreamChargers.co.uk are food-grade and intended solely for culinary use.
How many nitrous oxide canisters do I need?
It depends on your usage. One standard 8g cream charger fills approximately 0.5 litres of whipped cream — enough for around 4–6 servings. For occasional home use, a pack of 10–24 chargers is sufficient. For daily professional use, a 580g or 640g N₂O tank is far more cost-effective, replacing the equivalent of 72–80 individual 8g chargers.
What is the difference between 8g cream chargers and N₂O tanks?
8g cream chargers are small, single-use cartridges ideal for home bakers and low-volume use. N₂O tanks (580g and 640g) are large-format cylinders that hold significantly more gas — making them much cheaper per serving and better suited to professional kitchens, caterers, and restaurants. Tanks require a compatible regulator or dispenser attachment.
Which nitrous oxide canister brands are the best in the UK?
The most trusted N₂O canister brands available in the UK are Mosa, iSi, Liss, FastGas, and GoldWhip. Mosa and iSi are the most popular choices for 8g chargers, known for consistent fill levels and food-grade certification. FastGas and GoldWhip lead the large-format tank market. All brands stocked at CreamChargers.co.uk are fully food-grade certified and UK-compliant.

Nitrous oxide canisters are safe, legal, and essential for achieving professional-quality whipped cream in seconds.
