General information

Molecular Sieves

For drying, cleaning or separating liquids and gases.

Features:

• Spherical metal aluminium silicates
• 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

Typical application:

• In desiccators, drying tubes, columns
• For drying streaming gases
• For absoluting organic solvents
• For separating organic solvents

Regenerating:

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

  • Critical molecular diameter for frequently occurring molecules, in Å (1 angstrom = 10-10 m = 0.1 nm)
