General information

Molecular Sieves

For drying, cleaning or separating liquids and gases.


  • Spherical metal aluminosilicates
  • Spheres Ø 1,6-2,5 mm and 2,5-5,0 mm
  • Active surface: 600-700 m2/g
  • Activated at 500-600 °C; we nevertheless recommend activating the molecular sieve again before using it for the first time
  • In desiccators, drying tubes, columns
  • For drying streaming gases
  • For absoluting organic solvents
  • For separating organic solvents


• In drying cabinets at 200-300 °C
• Through pressure change or rinsing
