Molecular sieve 5 Å, 0.5 nm, type 522, pearls, 250 g, glass

Molecular sieve 5 Å is a pearl-form adsorbent with a nominal pore size of 0,5 nm (type 522), supplied for laboratory drying and selective adsorption work. Identified under CAS number 1318-02-1 and EG nr. 215-283-8, this material is The 5 Å aperture class is widely used when water and small polar molecules must be retained while larger species pass, supporting solvent drying, gas treatment, and related chemical laboratory operations. The product is presented as type 522 pearls, giving a free-flowing bulk solid that is convenient to charge into columns, cartridges, or drying vessels. Glass packaging helps protect the beads during storage and transfer in the chemicals store. This molecular sieve grade from manufacturer Carl ROTH sits in the general laboratory chemicals range and is selected whenever a 5 Å / 0,5 nm pore specification is required. Users should match pore size and bead form to the target molecules and process conditions defined in their methods. Only the stated identity, pore size, type, pearl form, and pack presentation are given; no additional capacity or regeneration claims are made beyond the manufacturer data provided.
