3A Molecular Sieve, 4X8 Mesh, 1 Pound (Actual 1lb 2oz) Standard Zeolite for Removing and Separating Water, Lab Grade Quality Allows Use in Many Applications, High Adsorption Capacity and Durable, 1lb

I was using this product to remove moisture from distilled ethanol for laboratory use. My only real complaint which is pretty big was they do absorb ethanol, but they absorb water. I'm able to achieve. A 98% ethanol solution. If I could get 99% I would have given 4 stars. The only problems is a 4-8% reduction in final yield due to the sieves absorbing some of the ethanol. For the price, I'd say it's still a great buy.

Terrible quality. Breaking and cracking apart in my hands. Very dusty and pretty much breaking apart from running my hands thru them.

It works

Bought this product a few times and will continue to buy. The quality is as expected, uniform and clean. I’ve been able to reuse the beads multiple times before I decided I wanted to replace them, but they look the same as they did when they first arrived even after repeated uses.

Good quality, good price.

Quality is much higher than simlar priced 3a on amazon. They are uniform, minimal dust, non-breaking and so good I no longer use the other type I bought here before.

Tested for both water absorption as well as permeability of ethanol and performed great and good price too

I unknowingly dropped my iphone in the ocean on the shore of Santa Monica beach. It was in water for about 15 mins. I bought this stuff and put it in a jar with my phone for 3 days. My phone works and the screen has no spots. It’s been about a year. Don’t use rice. Use this stuff. Trust me. I’m a chemist.
