Product Description
Molecular Sieves 4A are highly effective desiccants designed for deep drying and purification in laboratory and industrial settings. With a uniform pore size of 4 angstroms, these 1.5mm beads selectively adsorb water and other small molecules while excluding larger compounds. This makes them ideal for applications like solvent drying, gas purification, and refrigerant dehydration.
Qualigens Molecular Sieves 4A are widely used in research labs, educational institutions, and industries where moisture control is critical. Their high adsorption capacity and thermal stability ensure reliable performance even under demanding conditions. Whether you’re working with organic solvents, natural gas, or air drying systems, these sieves deliver consistent results.
For researchers and students, Molecular Sieves 4A provide a cost-effective solution for maintaining dry environments in experiments. Their reusability through regeneration further enhances their value, making them a staple in chemistry and engineering labs across India.

FAQs
What is the difference between 3A, 4A, and 5A molecular sieves?
Molecular sieves are classified by their pore size in angstroms. 3A sieves adsorb molecules up to 3Å (like water), 4A up to 4Å (including ethanol), and 5A up to 5Å (like normal paraffins). 4A sieves are the most versatile for general laboratory drying applications.
How long do Molecular Sieves 4A last?
The lifespan depends on usage conditions. In continuous applications, they typically last 1-2 years before needing replacement. With proper regeneration, you can extend their useful life significantly. Monitor performance through moisture breakthrough testing.
Can I use Molecular Sieves 4A to dry acetone?
Yes, 4A molecular sieves are excellent for drying acetone. They effectively remove water without affecting the acetone molecules. This makes them superior to other desiccants that might react with or dissolve in acetone.
What’s the best way to store unused Molecular Sieves 4A?
Store in airtight containers with minimal headspace. For long-term storage, consider using desiccator cabinets or vacuum-sealed bags. Always keep them away from humidity and chemical vapors that could pre-saturate the sieves.
Are Molecular Sieves 4A reusable?
Absolutely. You can regenerate them by heating to 200-300°C for several hours. Industrial setups often use continuous regeneration systems. For lab use, a simple oven or muffle furnace works well for batch regeneration.
