Product Description
When precision matters in your lab experiments, the Molecular Sieve 4A BAKER ANALYZED® Reagent from eqipped delivers unmatched performance. This activated molecular sieve is engineered to trap water and other small molecules, making it indispensable for drying solvents, purifying gases, and maintaining controlled environments in research and industrial applications.
Unlike generic desiccants, this Type 4A sieve offers a uniform pore size (4Å) that selectively adsorbs molecules like water, ammonia, and methanol while excluding larger hydrocarbons. The BAKER ANALYZED® certification ensures lot-to-lot consistency, so you can trust your results every time. Whether you’re preparing anhydrous reagents or protecting moisture-sensitive samples, this 500g pack provides ample supply for routine lab use.

Researchers and educators rely on this molecular sieve for applications such as:
- Drying organic solvents before synthesis
- Removing water from natural gas streams
- Preserving hygroscopic chemicals in storage
- Purifying argon and other inert gases
At eqipped, we understand the importance of quality lab supplies. That’s why we source this product from Avantor, a trusted name in scientific reagents. The 500g pack size is perfect for frequent users, reducing the need for constant reordering while maintaining freshness.
For best results, activate the sieve by heating at 300°C for 3 hours before use. Store in an airtight container to prevent premature moisture absorption. Remember, proper handling ensures maximum adsorption capacity and longevity.
FAQs
What is the difference between 3A, 4A, and 5A molecular sieves?
Molecular sieves are categorized by pore size: 3A (3Å) adsorbs only water, 4A (4Å) adsorbs water and small molecules like CO2, while 5A (5Å) can adsorb larger molecules like C4 hydrocarbons. Type 4A is ideal for general lab drying applications.
How do I regenerate used molecular sieve 4A?
Heat the used sieve at 250-300°C for 3-4 hours in a muffle furnace or oven. Cool in a desiccator before reuse. Avoid overheating as it may damage the structure.
Can this sieve be used for drying ethanol?
Yes, but note that 4A sieves will adsorb ethanol molecules along with water. For ethanol drying, consider using 3A sieves which exclude ethanol while removing water.
What’s the shelf life of activated molecular sieve 4A?
When stored properly in sealed containers, the shelf life is typically 2-3 years. Once opened, use within 6 months for optimal performance.
Where can I buy laboratory-grade molecular sieve 4A in India?
You can purchase authentic BAKER ANALYZED® Molecular Sieve 4A (500g) directly from eqipped’s online store with fast delivery across India.
