Product Description
When precision matters in your lab, the right desiccant can make all the difference. Molecular Sieve 4A, with its uniform 1.5–3 mm pellets, is engineered to trap water and other small molecules with unmatched efficiency. Unlike silica gel, this lab-grade sieve offers higher selectivity for moisture, making it the go-to choice for researchers and students working with sensitive solvents or gas streams.
Whether you’re drying organic solvents before a critical synthesis or purifying air for analytical instruments, this Avantor-certified product delivers consistent performance. The LR grade ensures minimal impurities, so you can trust your results without second-guessing your reagents. And because it’s regenerable, you get more value from every gram—simply heat to reactivate when needed.
At eqipped, we understand that lab supplies aren’t just products; they’re tools that shape discoveries. That’s why we source molecular sieves from trusted brands like Avantor, so you can focus on your work without worrying about quality. Need it fast? Our streamlined logistics ensure your order reaches you promptly, no matter where your lab is in India.

FAQs
What’s the difference between 3A, 4A, and 5A molecular sieves?
3A sieves adsorb only water, 4A sieves adsorb water and molecules up to 4 Å (like CO₂), while 5A sieves can adsorb larger molecules like n-paraffins. For most lab drying needs, 4A offers the best balance.
Can I reuse Molecular Sieve 4A?
Yes, it’s regenerable. Heat to 250–300°C for 2–3 hours under vacuum or dry gas flow. Cool in a desiccator before reuse. Avoid overheating, as it can degrade the crystalline structure.
How much sieve do I need for drying 1 liter of solvent?
A general rule is 5–10% by weight of the solvent. For 1L of ethanol (density ~0.789 g/mL), use 40–80 grams of 4A sieve. Always test for residual water if critical for your application.
Is this sieve suitable for drying acetone?
No, acetone’s ketone group can react with the sieve. For acetone, use calcium sulfate (Drierite) or calcium chloride instead.
How should I store unused molecular sieve?
Keep in an airtight container with a desiccant indicator. If stored properly, it retains full capacity for years. Avoid humid environments to prevent pre-saturation.
