TightVac 0.57l – Full-Ounce Vacuum Storage for Serious Growers
When your harvest fills more than a pocket container, the TightVac 0.57l is the logical next step. At 14.3 x 8.6 cm – roughly soda-can dimensions – and a capacity of approximately 45 grams of dry herbs, this is the container that handles a full ounce in a single organised unit. Compact enough for a kitchen drawer or grow room shelf, robust enough for the freezer. Explore the full TightVac collection to build a storage system that scales with your output.
How to Use the TightVac 0.57l
Fill the container to your desired level – up to approximately 45 grams depending on density – seat the lid firmly and press the vacuum button once. The patented one-way valve expels residual air and the hermetic seal engages in under a second; you'll feel the lid lock and hear the valve click. To open, hold the button while lifting the cap – the vacuum releases immediately without force. For freezer storage, allow the container to return fully to room temperature before opening, to prevent condensation forming on the contents. For maintenance, clean periodically with isopropyl alcohol or soapy water and dry the valve mechanism completely before resealing – a fully dry valve is essential for consistent vacuum performance across hundreds of cycles.
Use Cases & Applications

The Freezer Advantage: Why Size Matters Here
The 0.57l is the smallest TightVac format that is practically suited to freezer-based long-term storage. Its stable base diameter of 8.6 cm prevents tipping, and the full-ounce capacity makes it economical to dedicate a container to a single harvest batch. The vacuum seal actively removes residual oxygen before freezing – unlike standard containers where trapped oxygen continues degrading contents even at sub-zero temperatures. The EU-certified food-grade material is rated for freezer temperatures without brittleness or seal degradation. Tightpac, TightVac's manufacturer since 2005, produces all containers in their own factory using consistent, high-quality materials tested to EU food safety standards.

Is the TightVac 0.57l freezer-safe and how should I use it for long-term herb storage?
Yes, the TightVac 0.57l is fully freezer-safe. For long-term herb storage, fill the container, seal it with the vacuum button to expel residual air, and place it directly in the freezer. The vacuum seal prevents freeze-drying and blocks moisture ingress. When retrieving stored material, allow the sealed container to return to room temperature before opening – this prevents condensation from forming on the contents as warm air meets cold herbs. Properly used, this method is one of the most effective ways to preserve dry herb quality, potency and aroma over several months.
