Molecular Seives 4 A x 1.5 MM (250 Grams)

Molecular Sieves 4 Å are synthetic porous adsorbents designed for efficient drying, purification, and separation of gases and liquids in laboratory applications. Their uniform pore structure selectively adsorbs water and other small molecules, helping maintain sample integrity and improve analytical accuracy. Supplied in 1.5 mm pellets for convenient handling and consistent performance, they are widely used in research, educational, and quality-control laboratories for moisture removal and chemical processing procedures.
