PrimeWhip Food-Grade Cream Charger 640G Blueberry Blast

The 640g is PrimeWhip's middle size and the one most dessert sections settle on: big enough that it is not swapped daily, small enough to store on a shelf rather than the floor. This one carries a blueberry note that sits well on cheesecake, panna cotta and berry-led plates. The nitrous oxide is food grade, filled to a stated 99.95% purity, and one cylinder covers 85-plus cartridge equivalents. A pressure regulator is required to connect it.

Weekday versus weekend consumption

A dessert section rarely uses gas at a flat rate through the week weekend covers can run through several times the gas of a quiet Tuesday. The 640g cylinder, twice the fill of the 320g, gives most sites enough headroom to cover that swing without either running out on a Saturday or carrying an oversized 2000g body through a slow week.

It sits in the middle of the PrimeWhip range for a reason: sized for a section with real but uneven demand, rather than a single-flavour, high-volume production line.

Fitment and compatibility

It is a cylinder, not a threaded cartridge, and needs a pressure regulator fitted to its neck to feed a standard whipping siphon rather than a charger holder. That regulator carries over to any other PrimeWhip cylinder size bought afterwards.

Storage and handling

Keep it upright in a cool, dry spot away from heat sources and cooking equipment. The cylinder is sealed and single-use, so there is no refilling or maintenance step just secure storage until it is connected to a whipper.

Because it is never refilled, there is no pressure gauge to monitor between uses the only planning needed is having a replacement cylinder on hand before the current one runs dry mid-service.
