A Rotass Cream Charger is a small, sealed steel cylinder filled with Nitrous Oxide (N₂O) . It is designed to be used with a whipped cream dispenser. When you screw the charger into the dispenser, the gas is released, aerating the liquid cream. This process creates light, fluffy, and perfectly textured whipped cream in seconds. Beyond whipped cream, bartenders and chefs also use them to create foams, mousses, and molecular gastronomy infusions.
