These are advertised as 3a sieves, which should be unable to absorb ethanol, while still absorbing water. I purchased this to dry ethanol and decided to test and see if it actually is 3a before potentially wasting my ethanol.I measured 10mL of distilled water & 10mL of commercially purchased 99.9% ethanol and placed them in separate sealed bottles. I then filled them both with these sieves until the sieves were just under the fluid line. I left them for about a week and checked the contents.The result was just under 2mL of water in one bottle and just under 2mL ethanol in the other bottle. (I measured the fluids after pouring the contents through a strainer).So these sieves absorb water and ethanol about equally. They are not 3a as advertised.

These are reusable as long as you bake them in the oven and then vacuum seal them up

Good product. It would however be nice to have a resealable package since they are reusable.

A fantastic product at a great price. These molecular seives work just as expected and dried my solution to anhydrous conditions. Highly recommended from this independent, third party

Slightly dissolves in acetone. Not ideal, since this is what I'm trying to dehydrate

I saw some bad reviews saying this product doesn’t remove water from alcohol.This is my first time ever doing this and works great, the molecular sieves are ready for use them right away once you received them

These things are awesome. I was distilling some alcohol for use and needed the water to come out so poured these in and it just sucked up the water. Now my alcohol is super and without water.

Started with 95% ethanol, 48 hours after useing product and re-testing with hydrometer a reading of 94% registered. Baked fresh unused sieve at 350F for 4 hours , cooled in air tight jar, add to 94% ethanol, 24 hours later no change is %. Product seem to be defective . If I didnt wait so long from purchasing date to use ,I would have send it back.

This worked great for me. I found that it needed activating before use- it's shipped sorta semi-hydrated. Just roast it over a flame in an appropriate steel or glass vessel. I cooked mine for about 4 hours but i bet less will work nearly as well. I've heard they can be microwaved too but i haven't tried it.You can test them by putting half a teaspoon of room temperature product in your palm and drip some water on it. If it's ready to use they'll get real hot real quick! Enjoy.

Product came vacuum sealed in an aluminum foil package inside a yellow padded envelope which was sufficient for the purpose. The Molecular Sieve does an excellent job of removing water from Ethanol and are very easy to reconstitute for reuse by simply rinsing in warm water then bake dry at 200° for about 30 minutes spread out on cookie sheet and its ready to reuse.
