- 【3A Molecular Sieve】: 3A molecular sieve desiccant is a type of compound aluminosilicate desiccant whose effective pore size is 0.3nm. It is mainly used to absorb water and does not absorb and molecular larger than 0.3nm. Its application characteristics in industrial use are: rapid absorption seed, a mass of reusable times, strong anti-crash strength, and strong anti-pollution ability, which improves the use effectiveness of molecular sieve and extends its service life
- 【Complies with Industry Standard, Strict Quality Control】: Wisesorb 3A molecular sieve desiccant goes through strict quality control process before they are released from the factory. It complies with molecular sieve industry standard and ensure that every bottle if product are qualified and has premium quality
- 【Rapid Moisture Absorption, Reusable】: Wisesorb 3A molecular sieve has strong moisture absorption ability even under low temperature and low humidity rate. At the time, it still possesses certain moisture absorption under high temperature . It can be reactivated when dried under 550°C
- 【Wide Range of Use】: Pore size of 3A molecular sieve is 3A, which is applicable for drying of all types of air, hollow glass, refrigerating fluid, natural gas, methane, unsaturated hydrocarbon, pyrolysis gas, ethylene, acetylene, propylene, butadiene, etc. The date printed on the package is the manufacturing date not the expiration date
- 【How to Reactivate & Independent Packaging & Package Includes】: 3A molecular sieve can be placed in a muffle furnace and backed at 550°C (1020℉) for 2 hours, then transferred to a drying cylinder, and cooled to room temperature for use. 3A molecular sieve beads are stored in one plastic jar for long-term preservation & protection & store. Package includes 1 packs. The wide mouth jar makes pouring the sand back in extra easy

Poured a half cup of water on 100g and it immediately went into a bubbling frenzy. Water was ~20C to start and ~65C only a few seconds later.

good product, can be used to dry solvents

I bought this to dry 3D filament which I store in gasketted polycarbonate boxes. The humidity sensor in the box rapidly drops to <10% and with this desiccant it has been at that level for months despite frequent opening and reel swaps. I have three of these boxes, one of which I used fresh silica beads as a control. The silica took far longer to lower the humidity and started to fail after 8 weeks while this desiccant is still going strong after 4 months.
Beware others comments that this desiccant can be dried in a domestic microwave; DO NOT DO THIS. I have seen these ceramic beads molten red hot (ie in excess of 1200°C) from a microwave which is highly dangerous. Please use a low kiln or oven/air-fryer set to maximum to refresh these beads.

Does the thing that it’s supposed to do. Works great for keeping 3d filament dry.

Service was prompt and very happy with the item.

Room was at 30% humidity. this thing sucked it up down to 18% in under 20 minutes

I learned that molecular cyst could be used as a desiccant and they store more moisture collect more moisture and are easier to dry at higher temperatures. Why use anything else at this price

Alot of particulate introduced with the Sieves but they did their job.

We need very low humidity to store our dewpoint sensors. This product works perfectly.

One of the main reasons I bought these was to dry was to dry my isopropanol for a capsaicin extraction and I got a very pleasant surprise when I was about to drive my isopropanol first it was exothermic meaning it generates Heat second it had some dust inside which you can see in one of the pictures once the dust settles it should be good to go besides the dust these are a great product and I would highly recommend them also there was a”sealed for your protection” pieces of paper on top but when I went to lift it off it just kind of blew away when I did it right next to my air conditioner so I’m thinking they’re a little less dry than I originally thought also do not try to pour them into a small opening cuz when I tried it for my bottle they spilled everywhere but I would say these are pretty good product oh if you’re trying to pull out water from a chemical then use 3A

Using this for 3D printing, along with some stainless steel tea steeper containers.
Working amazing. Testing comparing against silica gel shows this to be far superior.
Cheaper, as well as easy to recharge. No toxic chemicals.
Would highly recommend looking up the whitepapers on the performance difference of alumina vs silica.

Nile Red said I needed these for anhydrous ethanol. I now have anhydrous ethanol according to the cheap meter I got on Amazon.
