SUPELCO Molecular Sieve Adsorbent, matrix Molecular Sieve 13X, 60-80 mesh, bottle of 50 g

Density: ~0.65 g/mL (free fall density)

General description: Molecular sieves are synthetically produced zeolites (naturally occuring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions. These crystalline materials have three-dimensional structures based on silicon oxide (SiO4) and aluminum oxide (AlO4) polyhedra. The polyhedra are linked by their corners to produce an open structure with internal cavities in which molecules can be trapped. These materials are engineered so that access to the internal cavities is through specific and uniform sized pores.

Other Notes: While molecular sieve materials are stable to above 400 °C, the temperature actually used at depends on the application. For example, GC column applications may work best with final oven temperatures of 225 °C, and gas purifier applications may work best at ambient temperature.
