SHIELDPRO 500cc Oxygen Absorbers - Packs of (10) Scavengers (10) (100 Total Absorbers)

Q: what is the difference between 300cc oxygen absobers and 500 cc oxygen absorbers?

Heya, thanks for the question. It is the number of CC of oxygen the absorbers will absorb before they stop working. For example, a 300cc absorber is rated to remove 300cc of oxygen from a closed container; this is the same as an empty 1.5 liter container (oxygen is roughly 20% of air, so 1.5 liters x 20% = 300cc). A 500cc oxygen absorber will clear an empty 2.5 liter container of air. In usage terms, a 1 gallon Mylar bag (3.7 liters) filled with rice will usually contain less than a third air (headspace), so maybe 1 liter of oxygen. Thus a 300cc will clear all the oxygen and have a chunk left over. Additionally, all of our products are overweighted, so a 300cc rated oxygen absorber when first opened may absorb up to 600cc total oxygen. This allows you sufficient time to work with it when storing your food.

Q: So these come in packages of 10 x 10? I hate buying the 100 ct in 1 single package because I usually can not use them all at once. Please advise.

Heya, thanks for the question. Yes, these are factory sealed in sets of 10. Thanks!

Q: How long to they last? Let's say I put one in a one gallon Mylar bag with rice and seal it. will the absorber hold the oxygen indefinitely?

I have opened a few Mylar bags after a year or so and they have held their vacuum and the food was great. I would have to say that the oxygen absorber had done its job and was still working. I have not had any seals fail on my Mylar bags. The seals on the bags are the key. As far as I know that is the only way that the absorber would stop absorbing oxygen would be if there is a bag seal leak and the absorber is used up trying to contain the leak. I hope this is clear.
