Product Overview
The 3A molecular sieve is a highly efficient desiccant designed for deep drying applications in laboratory settings. Composed of crystalline aluminosilicates with a uniform pore size of 3 angstroms, these beads selectively adsorb water molecules while excluding larger molecules, making them ideal for drying solvents, gases, and liquids. The 1.5 mm bead size ensures optimal flow dynamics and pressure drop characteristics, enhancing performance in both static and dynamic systems. This lab-grade molecular sieve is chemically stable, non-corrosive, and reusable after regeneration, offering long-term cost efficiency. Its high adsorption capacity and thermal stability (up to 600°C) make it suitable for critical drying processes where moisture control is paramount. The LR grade ensures minimal impurities, providing reliable results in sensitive applications. Whether used in packed columns, desiccant dryers, or storage containers, this molecular sieve maintains consistent performance across multiple regeneration cycles.
FAQs
1. What is the regeneration temperature for 3A molecular sieve beads?
Regenerate at 250-300°C for 2-3 hours in a dry air or nitrogen atmosphere to restore full adsorption capacity.
2. Can this molecular sieve be used for drying ethanol or methanol?
Yes, 3A molecular sieve is particularly effective for drying polar solvents like ethanol and methanol due to its strong water affinity.
3. How does the bead size affect performance in gas drying applications?
The 1.5 mm bead size provides a balance between surface area and pressure drop, optimizing contact time for efficient moisture removal in gas streams.
4. What is the typical water adsorption capacity of this molecular sieve?
Under standard conditions, 3A molecular sieve can adsorb up to 20% of its weight in water.
5. Is this molecular sieve compatible with acidic or basic solutions?
While stable in neutral conditions, prolonged exposure to strong acids or bases may degrade the aluminosilicate structure.
