Prepara Evak Glass Storage Canister, Medium 24oz – Borosilicate Jar with Patented Vacuum Lid for Coffee & Tea

The Prepara Evak Medium Glass Storage Canister is a 24oz borosilicate jar with a patented vacuum lid that removes trapped air to keep coffee, tea, and dry foods fresher longer.

This medium Evak canister combines museum-quality glass with an easy-to-use twin-valve lid: push down to evacuate air, then pull up to release the seal. Designed in the USA and proven in independent tests, the Evak outperforms ordinary airtight jars that simply trap stale air inside. It’s dishwasher-safe glass with a stainless-steel touch-point and no pumps, batteries, or complicated parts — just a tactile, reliable system built to preserve aroma and flavor.

How does the Evak lid actually remove air?

The Evak lid functions like a built-in plunger. When you press the lid down, the twin-valve system forces air out of the jar; lifting the lid reverses the seal so you can access contents quickly.

• Patented twin-valve design expels air without extra tools.
• Simple push-down, pull-up operation — no levers or pumps.
• Valves are permanent; no replacement parts required.
• Audible “whoosh” confirms air has been evacuated.

Will this container protect coffee, tea, and spices?

The medium Evak is sized and engineered to limit oxidation and preserve aroma for smaller quantities like half-pound coffee bags, loose tea, or frequently used spices. Because the jar is borosilicate glass, it won’t absorb odors or stains, and it gives a clear view of contents.

• 709 ml (24 oz) capacity fits ~½ lb coffee or several tea pouches.
• Glass interior resists flavors, stains, and lingering smells.
• Tight vacuum reduces exposure to air, slowing flavor loss.
• Clear profile makes inventory and portioning simple.

How do I clean and care for the Evak canister?

The jar body is dishwasher-safe for convenient cleaning; handwashing the stainless-steel lid and cap preserves finish and longevity. Disassemble the lid gently if needed and dry thoroughly before reassembling to keep the sealing surfaces working smoothly.

• Borosilicate glass: dishwasher-safe on the rack.
• Stainless lid: recommend hand wash to maintain shine.
• Check valves visually; no tools required to re-seat parts.
• Dry fully before storing to avoid moisture buildup.

What sizes and uses suit the Evak Medium best?

The medium measures approximately 3.6 in diameter by 5.75 in high and holds 24 oz, making it a versatile countertop or pantry jar. It’s ideal for coffee portions, loose-leaf tea, granola, dried fruit, or sweets that you want visible and protected.

• Medium size holds 24 oz (709 ml): fits half-pound coffee portions.
• Stackable, elegant design suits both pantry shelves and counters.
