While silica gel absorbs broadly, Wisesorb’s 3A Molecular Sieve targets water molecules with surgical precision — its 0.3 nm pore size selectively adsorbs water vapour while blocking larger molecules. The result: faster, deeper, and more stable drying for demanding applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3A Molecular Sieve – 0.3 nm Pore Size\u003c\/strong\u003e – Engineered to selectively adsorb water vapour while excluding larger molecules such as ethanol, CO₂, and hydrocarbons.

This makes it far more effective for precision drying in labs, industrial gas systems, and sensitive electronics — where silica gel may not achieve the required dryness level.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I fully regenerate 3A molecular sieve at home?\u003c\/strong\u003e\u003cbr\u003eFull reactivation requires a muffle furnace at 200–300°C. At home, a microwave can achieve partial reactivation: spread beads no more than 10 mm deep on a heat-resistant tray, heat at around 700 W for no more than 1 minute per interval, and repeat 3–5 times. This restores partial adsorption capacity but not full performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I reuse it multiple times?\u003c\/strong\u003e\u003cbr\u003eYes, 3A molecular sieve is designed for multiple regeneration cycles. However, adsorption capacity may gradually decrease over time. Replace when you notice a significant drop in performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe to use near electronics and food?\u003c\/strong\u003e\u003cbr\u003eYes. Wisesorb 3A molecular sieve is non-toxic and chemically inert, making it safe for use near electronics, laboratory equipment, and sealed food storage containers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much do I need?\u003c\/strong\u003e\u003cbr\u003eUsage depends on the volume of the enclosed space and ambient humidity. As a general guide, use approximately 1–2 g per litre of enclosed space, and adjust based on local conditions.\u003c\/p\u003e","brand":"Wisesorbent","offers":[{"title":"2 pcs","offer_id":53191742423378,"sku":"2lb-3A MS-2p","price":35.0,"currency_code":"EUR","in_stock":true},{"title":"4 pcs","offer_id":53191742456146,"sku":"2lb-3A MS-4p","price":65.0,"currency_code":"EUR","in_stock":true},{"title":"6 pcs","offer_id":53191742488914,"sku":"2lb-3A MS-6p","price":95.0,"currency_code":"EUR","in_stock":true},{"title":"12 pcs","offer_id":53191742521682,"sku":"2lb-3A MS-12p","price":180.0,"currency_code":"EUR","in_stock":true},{"title":"24 pcs","offer_id":53191742554450,"sku":"2lb-3A MS-24p","price":340.0,"currency_code":"EUR","in_stock":true},{"title":"36 pcs","offer_id":53191742587218,"sku":"2lb-3A MS-36p","price":480.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/7160\/7378\/files\/71Yl4pACf_L._AC_SL1500.jpg?v=1776156392","url":"https:\/\/wisesorbstore.com\/fr\/products\/wisesorb-900g-desiccant-balls-3a-molecular-sieve-reusable-moisture-absorber-dehumidifier-quick-humidity-control-for-cupboard-storage-electronics-and-tools","provider":"Wisesorb Store","version":"1.0","type":"link"}
