Prepara Evak Compact Glass Storage Canister, Medium, 6' x 3.75', 24oz

UPDATED REVIEW After nearly 2 years of using this, I have to give credit where it's due. The container and seal have held up despite my skepticism. We use it quite a bit and like it. There's room for some minor improvement, but, still a 5 Star product. ORIGINAL REVIEW This item does what it's supposed to. However, the design could use some refinement. First of all, the seal is a silicone-based ring that requires force when attempting to pull the lid off. That force is required to reposition the seal to accommodate upward travel. The stress on the seal during this process and its long-term use will likely lead to seal fatigue. Therefore, the longevity of the seal is a consideration. A better approach may have been to use a replaceable O-ring (any seal is wear item) with a press-button air relief valve on the lid for use during the lid on/off process. This design requires a precisely round cylinder shape of the glass jar and that precision may present a challenge to glass the manufacturing process, I'm not sure. It just seems (at least on my unit) the force required for lid-travel (up & down) will ultimately lead to a bad outcome under the current configuration and some redesign should be considered. Other thoughts: In its current design, the elderly may have some difficulty with the level of effort required for lid removal and could lead to glass breakage if the jar were to slip during the process. Also, although the glass jar seems to be of adequate quality, the sticker label (in my case crooked) seems cheap; as does the lid itself. Although the packaging is impressive, the manufacturer could have at least taken a bit more pride in the workmanship and small details.

I have lg. and sm. and ordering med now. Finally a product that actually works. Air tight! True vacuum seal. Others claim to be airtight and are not. I highly recommend. Easy to use and 'many years old it's still like its brand new'! The seal is absolutely perfect and glass sparkles. I find them to be an elevated look in any kitchen. As a designer I appreciate the style. I love seeing my coffee beans in the large and tea bags in the small. Good price for a great product. A 3rd is on it's way.

This a great looking storage container that is perfect for a half pound of coffee beans. The vacuum seal lid works great. And the glass container is easy to clean.

We've had one for 3 years and really like it. It does a great job of helping to keep the coffee fresh. However, the piston (for lack of a better word) on the new one was so hard to pull out I was afraid the handle would break as other reviewers have experienced. So I put the old piston in the new glass container and the new piston in the old one and both worked fine, that is, until I cleaned the old piston's seal. Then it became hard to withdraw from the new container too. I realized that the old piston seal and the old container had a thin film of coffee bean oil on them that allowed for easy removal of the piston without sacrificing the seal. I applied a little olive oil to make a very thin film--it doesn't take much--on the bore of the new container and that solved the problem.

I use this for coffee bean storage. I tried a 'vacuum container' and found that it only reduced the air pressure to about 0.65 bar (reduced pressure by about 35%), so 65% of the oxygen partial pressure remains. I used altimeter watch (barometric) to measure. Instead, I got this airtight container. This container fits closely on top of the beans reducing the ullage space to zero. But wait! There's more: the interstitial space still remains, so I attached a canula to a CO2 cartridge-based bike tire filler and used it (starting with the canula at the bottom of the container) to fill the container full of coffee beans with CO2. Roasted coffee outgasses CO2 naturally. I think this is a pretty straight-forward solution. The nice thing with the CO2 is that you can check to be sure the gas level is at the top of the container by sniffing the container opening. The CO2 is heavy and has a pungent 'smell'. If I used helium, it would float away, if I used argon I wouldn't be sure the container was full. Anyway, works great; every time I get beans for coffee, I refill the container with CO2, sniff to verify gas blanket extends to top of container, and replace top, displacing excess CO2 while the interstitials remain filled with the CO2. Done and done.

Thick glass. Simple design. Good quality. Excellent coffee storage.

I really liked the simplicity of this airtight storage container. But the glass is too thin and weak to serve its purpose. In fact, it broke on only the third time I used it. When it arrived I recognized that the glass container was fragile and I would have to be very careful not to accidentally bump it into other solid objects. I’m careful with fragile objects, but what actually caused it to break really surprised me: as I slowly lifted the lid up and out I didn’t realize that I wasn’t keeping it perfectly horizontal. So when the solid metal lid was at a slight angle while I moved it, the glass suddenly cracked from that slight pressure. A single large piece broke out (see pictures). Poor design. I wasted my money.

I wanted a coffee storage container that was easy to open and easy to close and was not messy to use. I just put the coffee in the container, and them I push down on the cover and it slides easily into the container. I can feel the air flowing out of the container, through the cover, when I push it down onto the coffee. The cover is easily removed and allows air back into the container as I pull it out. The container is wide enough to allow me to move my hand down into the bottom of it to get coffee out without having to tip the container over and then pour out the coffee to allow me to reach it. If you push down too hard on the cover, then the bottom of it will push into the coffee and coffee grounds will get pushed into the vents. I am happy with this unit!

I'd seen this on Baba or You Tube, I forget, but I ordered two of them immediately. I'd just bought myself the amazing BUNN coffeemaker and what better way to keep coffee fresh than this wonderful storage cannister? It's made of good thick glass, and the top slides down to press against the contents, thus removing any air. That keeps whatever's inside fresh; in my case, decaf coffee in one, regular in the other. Just push the top down as you use up the contents, then toss it in the dishwasher and refill. (Note: I love Amazon.ca. One of my first two containers arrived broken. I called Amazon and explained I didn't want to be returning broken glass, which my Amazon customer service rep understood. I couldn't believe it when not one but the entire order was replaced and at my door the day after next that I'd called!!!)

I'm happy about this purchase. It never disappointed me. It is what it was described as: good quality, good packaging. Overall, it is an excellent product.

Bought these for celery juice so I can prepare it in advance and they work really well to keep it fresh. I cut up an apple and left it in the jar in the fridge for about 3 days. The apple didn’t go brown. Easy to clean too. Great product.

Exactly what I need and no issues after few months of usage.

O vidro é grosso, ótimo material no geral, super recomendo, não ocupa espaço, bonita e elegante, veda bem, cumpre o que promete, discreta porém chama a atenção por ser muito "chique"! Podem comprar sem medo, excelente para presentear com originalidade!
