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 for Puppies!
Color: Red
This toy has been a great purchase for my new puppy! He has so much fun playing with it and stays engaged for long periods. While it can move a little fast at first, the adjustable speed settings make it easy to customize. Overall, it’s a fantastic toy that keeps him active, entertained, and happy.

Good for (non-destructive) small dogs
Color: Red
Bought for a small dog, would not recommend for a destructive chewer. After some initial hesitation this has become her favorite toy and keeps her entertained for a good while. The different settings provide some variety to how she can play with it. The battery only lasts about an hour, but it does charge quickly. As others have noted the string is garbage.

Cool gadget for you puppy!
Color: Red
Do you need a break sometime? Something that you puppy can play with for 20 or 30 minutes at a time? This is it! It goes around the place in random paths that will keep your puppy entertained and amusedZ. It not to loud and it lasts a long time and nothing has broken off form the rough play at all.

Great for small dogs with a big prey drive!
Color: Red
He loves it!! I have a small dog with a big prey drive and he goes absolutely crazy for this! A big plus for taking the boredom away, really perking up his mental attitude. It's also (at this moment) much cheaper than others that look very similar. Super easy to charge. My dog is a rescue and never learned to play with toys, has zero interest in stuffed toys and doesn't really understand play, but this isn't play to him: It's what he was born to do. He gives it a hearty Two Paws Up!

Our Yorkie Puppy Loves This Toy!!!
Color: Red
Warning: your pet may become completely obsessed I’ve had this toy for about a year for my Yorkshire Terrier, Gia, and it’s easily the most successful toy purchase I’ve ever made. We even had to replace the first one after she loved it a little too much (chewed the string off), and have since bought more as gifts for friends’ pets. Great toy for small dogs (too fragile for bigger dogs) and active, young cats.) What we love: * Endless engagement: Gia ignores all her other toys and goes straight for this every time * Interactive features: Subtle beeping + changing colored lights + unpredictable rolling patterns keep her hooked * Energy burner: Perfect for indoor play on hardwood floors—she will chase it nonstop * Rechargeable: Battery lasts several hours, even with frequent use * Durability: Holds up well considering how rough she plays Real-life note: Gia will literally bring this toy to me to get me involved—and I have to limit her playtime because she won’t stop on her own. Bottom line: If you have a high-energy dog (or even a playful cat), this isn’t just a toy—it becomes their favorite activity… and possibly their entire personality.
