Hello there Trucker! You can use the Duo Nova for what's known as "water boil canning". However, please ensure that you do not pressure can in this model. Pressure canning requires a minimum 15psi, whereas the Duo Nova is only rated up to 12 psi. This means that it does not reach pressures for safe canning. We currently have two Instant Pots that are capable of pressure canning. The 6 quart Max model and the 6 quart Pro Plus. If you have more questions please reach out to our support team!
