Precision Adsorbents for Moisture Removal, Solvent Drying & Gas Purification

Molecular Sieve Beads are synthetic crystalline aluminosilicates engineered with uniform pore structures that selectively adsorb molecules based on size and polarity. Unlike general desiccants, molecular sieves provide targeted adsorption, allowing precise removal of water and impurities while excluding larger molecules—making them ideal for solvent processing, gas drying, and high-purity applications.

These beads are manufactured with high crush strength, low attrition, and consistent particle sizing to ensure reliable performance in packed columns and inline filtration systems. Their strong affinity for water enables ultra-low moisture levels, including dew points below -100°C when properly regenerated.

Available Types


3A Molecular Sieve Beads (3A Pore Size)

Selective Water Adsorption – Ideal for Solvent Dehydration

3A molecular sieve is the potassium-exchanged form of Type A zeolite with a pore opening of approximately 3 angstroms. It selectively adsorbs water while excluding larger molecules such as hydrocarbons and most alcohols, making it highly effective for drying sensitive solvents.

Key Features:

Adsorbs molecules <3A (primarily water)
Excludes hydrocarbons and larger organics
High adsorption capacity (~21 wt% water)
Excellent for moisture-sensitive systems

Applications:

Solvent dehydration (ethanol, benzene, toluene, hydrocarbons)
Natural gas and cracked gas drying
Refrigerant and air drying
Static and closed-system moisture control

Typical Specifications:

Pore Size: ~3A
Form: Spherical beads
Water Adsorption: ≥21 wt%
Bulk Density: ≥0.70 g/mL
Regeneration Temp: ~200–230°C

4A Molecular Sieve Beads (4A Pore Size)

General-Purpose Drying & Broad Moisture Removal

4A molecular sieve is the sodium form of Type A zeolite with a 4 angstrom pore opening. It adsorbs water along with small polar molecules such as CO₂, H₂S, and light hydrocarbons, making it a versatile, general-purpose desiccant.

Key Features:

Adsorbs molecules <4A (water, ammonia, CO₂)
Broader adsorption range than 3A
High capacity and rapid adsorption kinetics
Strong mechanical integrity for repeated cycles

Applications:

Air and gas drying systems
Solvent dehydration (less selective than 3A)
PSA and TSA drying systems
Packaging, electronics, and moisture-sensitive storage

Typical Specifications:

Pore Size: ~4A
Form: Beads or pellets
High static water capacity
Durable, regenerable structure


13X Molecular Sieve Beads (10A Pore Size)

Maximum Adsorption Capacity & Broad Spectrum Removal

13X molecular sieve (also known as Type X) features a larger pore size (~10 angstroms), enabling adsorption of a wide range of molecules including aromatics, CO₂, sulfur compounds, and larger hydrocarbons. It offers the highest capacity among common sieve types.

Key Features:

Adsorbs molecules <10A (large organics, aromatics, CO₂)
High adsorption capacity and throughput
Effective for impurity and color body removal
Strong affinity for polar and non-polar compounds

Applications:

Gas purification and air separation
Hydrocarbon and solvent processing
Removal of CO₂, H₂S, and sulfur compounds
General-purpose adsorption where selectivity is less critical

Typical Specifications:

Pore Size: ~10A
Form: Spherical beads
High capacity for large molecules
Regenerable via thermal or pressure swing methods

Great quality, color is ok.
Color: Cream Brown, Size: 2 x 6 ft Sheepskin
The quality, texture, feel and smell of the rug is very good. The hairs adhere to the back lining well and don't shed even with my cat trying to bite it out. The only downside unfortunately is aesthetic— the cream brown I ordered, in natural light/sun shining on it, looks more yellowish - gold.

Great Quality!
Color: Ivory White, Size: 2' x 6' (Sheepskin Shape), Color: Ivory White, Size: 2' x 6' (Sheepskin Shape)
I have owned many sheepskins before and this one is by far the best deal. Cheaper than similar sizes, but not in a bad way! It’s a beautiful creamy white, super plush, and is very long. We keep it on the back of our couch and it gives a very cozy vibe. I haven’t had any issues with it shedding. Word of advice for cat owners: When we first got it, it did have a sheepskin smell but it isn’t a gross smell and it went away within a few days; however, my cat was very attracted to that smell and was “attacking” the sheepskin. We trained her not to do it just by spraying her with water—after a few times of that she stopped going anywhere near it. Now that the smell has dissipated, she isn’t attracted to it anymore but does like to sit on it every once and awhile (I can’t blame her, it’s sooooo soft). I saw someone else say their cat ruined their rug, so I wanted to give our story on how we prevented that and hopes it helps another cat owner. You just have to be alert for the first day, maybe even let it off-gas outside first, then keep a spray bottle nearby and the cat should stop messing with it!

Great little rug!
Color: Ivory White, Size: 2' x 3' (Sheepskin Shape), Color: Ivory White, Size: 2' x 3' (Sheepskin Shape)
This nice little sheepskin rug is the perfect finishing touch to my little reading nook. It’s soft and thick. Follow the enclosed instructions to fluff it up. I was going to order a second one but saw that the price jumped nearly $10 in a week. It’s nice but it’s not worth that amount. I’d buy it on sale though. Five stars.
