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. - 【Wide Range of Use】: Pore size of 3A molecular sieve is 3A, which is applicable for drying of all types air, hollow glass, refrigerating fluid, natural gas, methane, unsaturated hydrocarbon, pyrolysis gas, ethylene, acetylene, propylene, butadiene, etc. - 【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 - 【How to Reactivate】: The 3A molecular sieve can be placed in a muffle furnace and baked at 550°C (1020℉) for 2 hours, then transferred to a drying cylinder, and cooled to room temperature for use. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 288 Reviews | ## Images ![Wisesorb 7 LBS 3A Molecular Sieve, Premium Quality Desiccant Bulk Material - Image 1](https://m.media-amazon.com/images/I/716IY-6gXGL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Do these come fairly dust free or could they be run through a Buchner vacuum w/ cheesecloth to clean?** A: Mine was completely dust-free. I dumped them directly from the container to a muslin bag for my safe. **Q: Are the 3A molecular sleeves actually 3A size and are they clean (price seems too good)?** A: yes **Q: Is the regeneration temperature really 550°c? other sources that i can find all list 300c (550f) or 315c (599f) as the maximum temperature to use.** A: Hi, Thank you for your question. The reactivation temperature for our product, 3A Molecular Sieve, is 550°C. **Q: How many times can you reactivate 3A Molecular Sieve?** A: 【How to Reactivate】: The 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. ## Frequently Bought Together - Wisesorb 7 LBS 3A Molecular Sieve, Premium Quality Desiccant Bulk Material - Wisesorb 20 Packs Breathable Paper Bags, Zip Lock Storage Bags for Small Items, Silica Gel Beads, Desiccant, Jewelry, Samples, 4.3 by 6.3 Inch - Wisesorb 7.5 LBS 4A Molecular Sieve, Premium Quality Desiccant Bulk Material --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/201413371-wisesorb-7-lbs-3a-molecular-sieve-premium-quality-desiccant-bulk](https://www.desertcart.vn/products/201413371-wisesorb-7-lbs-3a-molecular-sieve-premium-quality-desiccant-bulk) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-07-22*
