Product Description
Molecular Sieves Type 5A are highly effective desiccants designed for precise adsorption in laboratory and industrial applications. With a pore size of 5 Ångströms, these 1.5mm beads selectively adsorb molecules like water, CO₂, and H₂S while excluding larger hydrocarbons. This makes them ideal for drying gases and liquids, purifying solvents, and separating air components in research settings.
Whether you’re a student setting up a chemistry experiment or a researcher refining a process, these molecular sieves ensure consistent performance. The uniform bead size (1.5mm) allows for efficient packing in columns or reactors, maximizing contact surface area. Unlike silica gel, Type 5A sieves maintain stability at higher temperatures, making them suitable for regenerative processes.
At eqipped, we source these molecular sieves from trusted manufacturers to guarantee batch-to-batch consistency. The CDH-branded product (160835) meets stringent quality standards, ensuring reliable results in critical applications. Available in convenient pack sizes (250 gm, 5 kg, 25 kg), you can choose the quantity that fits your lab’s needs without overstocking.

How Molecular Sieves Type 5A Work
These zeolite-based adsorbents function through a process called physical adsorption. The crystalline structure contains tiny pores (5 Å) that trap molecules small enough to enter while rejecting larger ones. This selectivity is why they’re preferred for:
- Drying natural gas streams
- Removing moisture from refrigerants
- Purifying argon in air separation units
- Dehydrating organic solvents like ethanol or acetone
For best results, activate the sieves by heating to 250-300°C under vacuum or inert gas flow before use. This drives off pre-adsorbed water, restoring full capacity. Always store in airtight containers to prevent premature saturation.
Safety and Handling
While generally safe, molecular sieves can cause irritation if inhaled or contacted with eyes. Always wear appropriate PPE (gloves, goggles) when handling. Avoid generating dust during transfer. In case of skin contact, rinse thoroughly with water. For accidental ingestion, seek medical attention immediately.
Why Labs Trust This Product
Researchers across India rely on this specific CDH product (160835) because of its:
- Consistent particle size distribution (1.5mm beads)
- High adsorption capacity (up to 20% by weight)
- Low dust formation during handling
- Compatibility with most organic solvents
From university chemistry labs to pharmaceutical R&D centers, these molecular sieves deliver reproducible results. The 5 kg and 25 kg options are particularly popular with institutions running multiple experiments simultaneously.
Common Applications in Indian Labs
In academic and research settings across India, Type 5A molecular sieves are frequently used for:
- Drying solvent systems in organic synthesis
- Preparing anhydrous reaction conditions
- Purifying carrier gases in chromatography
- Moisture removal from compressed air lines
- Dehydrating biofuels during analysis
Many IIT and NIT laboratories stock these sieves as part of their standard consumables inventory. The 250 gm pack is perfect for student projects, while larger quantities support ongoing research programs.
Storage Recommendations
To maintain optimal performance:
- Store in original sealed containers
- Keep in a cool, dry place (below 30°C)
- Avoid exposure to atmospheric moisture
- Use desiccator storage for opened packages
Properly stored molecular sieves can be regenerated multiple times, offering excellent cost efficiency for budget-conscious labs.
FAQs
What’s the difference between 3A, 4A, and 5A molecular sieves?
3A sieves adsorb only water, 4A adsorb water and some larger molecules, while 5A (like this product) can adsorb molecules up to 5 Ångströms, including CO₂ and H₂S.
Can I regenerate these molecular sieves?
Yes, heat to 250-300°C under vacuum or inert gas flow for 2-3 hours. Avoid exposure to air during cooling to prevent re-adsorption of moisture.
What’s the typical lifespan of these sieves?
With proper regeneration, they can last for dozens of cycles. However, capacity gradually decreases with each regeneration cycle.
Are these sieves suitable for food-grade applications?
This laboratory-grade product isn’t certified for food use. For food applications, you’d need food-grade molecular sieves with appropriate certifications.
How quickly do you deliver to Indian cities?
eqipped typically delivers to major cities like Bangalore, Mumbai, and Delhi within 3-5 business days. Remote areas may take 7-10 days.
