Yes. Several listings include an external vacuum or hose function designed for jars, canisters, bottle preservation (e.g., wine stoppers) and marinating. That external suction lets you use the unit with containers and marinators in addition to sealing bags.

Product listings report a range of suction values, for example: 80 kPa, 85 kPa, 90 kPa and −95 kPa. These are the vacuum/suction figures shown across different models in the results.

Listings mention specific sealing lengths and roll storage examples such as an 11.8" maximum sealing length, a 13" roll storage compartment, and included bag rolls like a 20×300 cm roll.

Sealing times vary by model; examples in the listings include about 8–18 seconds for a seal, while other models describe sealing in under 30 seconds.

Machine bodies and parts are described as stainless steel and plastic. Bags are listed as PA+PE, and one travel pump lists polyamide.
