Tanks are sold by the weight of gas inside, not the size of the cylinder — which is why a “3.3L” and a “2000g” tank on two different websites are usually the same object. The weight is the number that matters, because it decides how many portions you get and what each one costs you.
We carry three formats. Here they are against each other, priced from the shop as it stands today.
| Format | Equivalent 8g chargers | From | Cost per 8g equivalent | Who it suits |
|---|---|---|---|---|
| 640g | ~80 | $54.99 | $0.69 | Low volume, or several stations each wanting their own |
| 1364g (2.2L) | ~170 | $59.99 | $0.35 | Cafés busy enough to outgrow 640g, not busy enough for 2kg |
| 2000–2112g (3.3L) | ~250–264 | $61.99–$100.99 | $0.24–$0.40 | Restaurants, bakeries, caterers working at volume |
The direction of travel is obvious: bigger is cheaper per serving, and the drop from 640g to 2kg is roughly two-thirds. The catch is that you pay more per tank up front, and an opened tank that lingers for six weeks is a worse outcome than paying a few cents more per portion.
Go deeper
Most kitchens are really choosing between two of these, so we wrote the comparisons properly: 640g vs 2kg is the decision most people arrive with; 1364g / 2.2L covers the middle format and why it is scarce here; 2000g / 3.3L ranks every large tank we stock on cost per serving.
Before you order anything
One thing surprises people moving up from 8g bulbs: a tank does not screw into the dispenser. It feeds through a pressure regulator and hose into the same inlet the bulb holder uses. You buy the regulator once and it works with every tank and every brand we carry — but if nobody tells you, your first delivery arrives and you cannot use it.
Shop by format
Everything here is food-grade nitrous oxide, sold for culinary use and nothing else. Store tanks upright, below 50 °C, out of direct sun and out of reach of children. You need to be the age of majority in your province to buy.
