This standard size 1/2L whipper will make up to 1.5L of fresh whipped cream or cold espumas in an instant! Uses 8g nitrous oxide (N2O) cream charger gas cartridges to whip and propel the cream. Nitrous Oxide cartridges are cheap and easy to use. Nitrous Oxide also acts as a natural anti-biotic so the cream stays fresh in the whipper for up to 10 days if kept in a fridge. Only suitable for making whipped cream or cold espumas.
