Liquids can be vacuumed in small quantities without any problems. It is always advisable to have a Lava vacuum sealer with a 2- or 3-welding for this use case. In larger amounts, for example, soups, sauces, and stews, the Lava recommends only vacuum cases. These are available as gastronorm vacuum cases or in plastic or stainless steel. The suction device, which is necessary, comes with your Lava by default.
