MOLECULAR SIEVE 0.3 NM 250 G

General description

Molecular sieves are crystalline, synthetic zeolites. Their crystal gratings are similar to a cage with numerous hollow spaces. The cavities are accessible from all sides by pores of exactly defined dimensions.

Application

Molecular sieves can be used:      

• in desiccators and drying tubes      
• for keeping absolute solvents dry      
• for drying gases or solvents in drying columns    
• for selective adsorption

Features and Benefits

• Easy to use: practically chemically inert, non-toxic, no disposal problems, dried liquids can be decanted      
• High adsorption capacity even with a low water content of the substance to be dried     
• High adsorption capacity even at high temperatures      
• High adsorption affinity for polar and unsaturated organic molecules (however, H₂O is always preferentially adsorbed)     
• Selective adsorption: only molecules that can pass through the pores are adsorbed
