With chamber sealing technology, you'll be able to increase the shelf-life of your home-packaged perishables better than ever. The MaxVac® Pro is a heavy-duty chamber sealer seals all types of foods, including liquids like soups and stews, preserving flavor and nutrients, and preventing freezer burn. It's also ideal for marinating meat and making boil-in (sous vide) bags. Compact and lightweight, this convenient countertop chamber sealer features a maintenance-free pump and a multi-function digital control panel that allows you to easily adjust adjustable vacuum and seal times. A digital light bar shows the vacuum progress, and the transparent lid lets you see inside the chamber and watch the progress, while the silicone gasket ensures an airtight chamber. The chamber accommodates canning jars (quart, pint, or jelly) laying down. Use the canister port inside the chamber for sealing accessories and larger jars; vacuum hose included. The Marinate function runs 3 times consecutively without sealing, speeding marinate time from hours to minutes. Includes riser insert to level and take up space in chamber. Removable heat bar makes cleanup easy.
