The Good Housekeeping Research Institute conducted tests on storage containers (both plastic and glass) to see which brands kept food fresh for longest. They also tested for leakage by shaking the containers and leaving them upside down. They assessed whether moist air was entering the sealed containers by placing silica gel beads in the container (they turned pink if air was entering). Finally they tested for staining, by microwaving tomato sauce in the containers. As you can guess, all the plastic containers got stained, but the glass ones did not. You can read their results here.

Of the glass storage containers they tested, here are the top three results:

1. Snapware Glasslock. They didn’t get stained and GH felt that the glasslock tabs were easy to use. You can see our snapware listings in the sidebar on the right or by clicking the Snapware category at the top.

2. Anchor Hocking Trueseal. The lids of the Anchor Hocking Trueseal containers got a perfect score for keeping air out of the container. This means they are perfect for storing foods such as sugar, which needs to be in a perfectly dry container (as water droplets in the air melts the sugar). They also didn’t leak when the container was turned over. Anchor Hocking Trueseal containers double as cookware and bakeware because they can go into the oven as well as microwave, which makes them one of the most versatile types of container.

3. Bormioli Rocco Frigoverre. They found the glass bottoms to be stain proof, but the lids not as air-tight as the Anchor Hocking containers. But they scored for being the most aesthetically pleasing (they come with brightly colored lids and the frigoverre range has patterns on the sides of the bowls).
