Molecular Sieves

Molecular Sieve

The 3A molecular sieve is an alkali metal aluminosilicate with a pore opening of approximately 3 angstroms. Type 3A is made by ion-exchanging the sodium in the type 4A sieve with potassium. The 3A molecular sieve will exclude most molecules except water, making it very selective. This type of bead also has advantages in crush strength, durability and high rate of adsorption. The 3A molecular sieve can remove moisture in both liquid and gas applications. Type 3A is used in the production of insulated glass, refrigerant drying, general moisture removal and the drying of natural gas, hydrocarbon liquids, ethanol and reactive monomers such as olefins.

Molecular Sieve

The 4A molecular sieve is an alkali metal aluminosilicate with an effective pore opening of approximately 4 angstroms. The sodium form of type A is widely used as a general-purpose drying agent and has good physical and adsorption properties. Type 4A beads can be used to adsorb water, ammonia, methanol, ethanol and carbon dioxide. This type of molecular sieve is often used to remove moisture from gas and liquid streams, where co-adsorption of sulfur compounds and carbon dioxide is not a concern.

Chromatography Gels - Irregular Shape

ZEOprep Unbonded Silica

Unbonded ZEOprep silica is mostly used as column packing material for preparative chromatography and the purification of natural products, food and cosmetic ingredients, as well as in the purification of active pharmaceutical and nutraceutical ingredients. The unbonded silica is produced in a broad spectrum of various pore sizes, particle size distributions and residual water contents. These modifications make ZEOprep the preferred choice for a wide array of applications. ZEOprep materials work efficiently under various separation conditions; diverse types of solvents, columns and pressure designs; and different types of crude or target compounds.

ZEOprep Bonded Silica

Bonded ZEOprep silica is used in liquid chromatography, flash chromatography and solid phase extraction. It can be used as scavengers and in chromatographic purifications steps when manufacturing active pharmaceutical ingredients (APIs). The vast ZEOprep product range provides outstanding lot-to-lot homogeneity based on defined quality parameters that ensure reproducibility in large-scale industrial applications. Our products also provide the most reliable separation power in commonly used techniques such as flash chromatography as well as in analytical applications.
