Best Molecular Sieve 3A Supplier in China

Zonebao Molecular Sieve Co., Limited is a leading molecular sieve 3a supplier. We also offer molecular sieve 4a and 5a. We have the recent supplies and equipment to the science community. As per the convention of the founders, we offer individualized, innovative scientific equipment, client service, and a comprehensive portfolio providing a wide selection of product listings at a massive deal.

Molecular sieve 5A products offered at Zonebao are alkali metal alumino-silicates in a spherical structure. They are in the calcium form generally in the Type-A crystal structure along with a significant 5A pore opening. Molecules having effective diameters greater than 5A, for instance, iso compounds alongside all 4-carbon rings will not be adsorbed. It can’t adsorb molecules smaller than 5A like molecular sieve 4a. Molecules that are adsorbed include C3H8 to C22H46, NC4H10, nC4H10, and Freon 12 (dichlorodifluoromethane).

Our molecular sieve 4a products are alkali metal alumino-silicates. They are in the spherical form similar to molecular sieve 5a. They are made in the sodium form of the crystal structure (Type-A) with a significant 4a pore opening. Our 4a molecular sieve can adsorb molecules such as nitrogen, oxygen, carbon dioxide, and straight-chain hydrocarbons. Branched chain hydrocarbons and aromatics will not be adsorbed.

Quality Molecular Sieve 4A Supplier in China

We have maintained the rapport as a professional molecular sieve 3a supplier where professionalism is the key. We have a firm belief that proper resources can only provide adequate support to our customer if we talk about the provision of quick solutions.
