General information
Molecular Sieves
For drying, cleaning or separating liquids and gases.
Properties:
- Spherical or powdered 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
Regenerating:
• In drying cabinets at 200-300 °C
• Through pressure change or rinsing
