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 suit, but size up
Size: Large, Color: Black, Size: Large, Color: Black
This set comes with a jacket, pants, extra buttons, and a bow tie with an easy clip to remove it. The suit itself is really nice and I love the pattern, however, I thought I purchased a XXL, but seemed to have ordered a L instead. Not quite sure how that happened, but suffice to say, he could not fit the suit. He is normally an L in pants, so based on the fit, we would have needed to size up anyways. He couldn't fit his leg in the pants or his arm in the jacket. I automatically size up on items like this because you can take clothes in, but can't take them out if there is not enough cloth. The suit pants are not lined, but you can see that they did leave room for the legs to be let out. Perhaps if we have the pants let out, he would be able to wear the pants. The jacket is fully lined and it comes with two inside pockets, one can be buttoned. I cannot tell if the jacket has room for alterations, but I might have him fitted for it just to see. It comes with a slit on the back of the jacket, so it has that going for it from a quality standpoint. It does come folded so you have iron or dry clean it before wearing. The quality is good for the most part. There are some threads coming out of the bow tie, but that's all I seen that is less the good. I'm giving it four star based solo on it's look and feel. Of course, I can't comment on the fit. For around $80, I definitely think it's worth checking out for a school semi-formal or fancy dinner out. It might be a little lightweight for a higher end event. Did I say I love the pattern?

Stylish look and great value for special occasions
Size: X-Large, Color: Blue, Size: X-Large, Color: Blue
This suit looks really good in person. The pattern adds a nice touch that makes it stand out without looking too flashy. It is a great option for events like weddings, parties, or prom where you want something a bit different from a basic suit. The fit is slim and modern, giving a clean and sharp look when worn. It feels comfortable enough for a few hours, and the overall shape looks more tailored than expected for the price. The jacket sits well, and the pants match nicely to complete the set. The material is lightweight and decent for occasional use. It does not feel like a premium suit, but it looks good and photographs well, which is what matters for events. The bow tie included is a nice extra and helps complete the outfit without needing to buy more pieces. It may need a quick steam or ironing out of the package to look its best. Also, checking the size chart is important to get the right fit. For the price, this is a very good value. You get a full outfit that looks stylish and put together without spending too much. Great option if you need something affordable for special occasions.

Stylish Statement Suit for the Price
Size: Medium, Color: Gold - Embroidery, Size: Medium, Color: Gold - Embroidery
I really like the black with gold embroidery on this suit - it really will make you stand out. The gold does have a slight green tint to it in certain lighting, but overall I like the unique design and think it looks great. The pants have some flexibility, which made them more comfortable than I expected. I got a Medium - and im usually a 32W. I could see it fitting a 30W or34W too. It arrived in great shape and was not wrinkled at all, though i'm likely going to have to hem the pants 1-2 inches. The pants are neutral and could be worn with other black jackets. I am usually a size 42 bust in jackets, and while the size chart says medium is a 44 bust, i think this fits me like a glove. It also came with a bow tie, which is a nice added bonus. Overall, I think this is a great deal for the price and a solid choice for anyone looking for a versatile standout suit for a formal event or a costume party.

Way better than expected - Not a "costume" at all!
Size: X-Large, Color: Christmas Green
I’m going to be honest: I was fully prepared to open this package and find a cheap, shiny, flammable-looking costume that belonged in a discount Halloween store. Buying a tuxedo on Amazon feels like a total gamble, and I was definitely a skeptic. I couldn’t have been more wrong. This suit is actually fantastic. First off, the fabric. It doesn’t have that "plastic" feel I was dreading; it actually feels elegant and has a nice weight to it. The floral pattern is sharp and the colors are vibrant without being "too much." It looks way more expensive than the price tag suggests. The fit was the biggest surprise. I’m always wary of "slim fit" labels, but this hit the mark perfectly. It’s tailored in the right places without feeling like I’m about to burst a seam if I sit down. I originally bought this thinking it might work for a one-off event, but now I’m genuinely excited to break it out for an upcoming casino night and a wedding later this year. If you’re on the fence because you’re worried about Amazon quality, just go for it. This is a legitimate suit that’ll definitely get you some compliments. 10/10 would buy again.

Showstopper! Incredible Fit and Stunning Floral Design!
Size: Medium, Color: Black
I bought this Mgnaie floral tuxedo for a special event, and I was absolutely blown away by the quality and the fit! Getting a slim-fit suit online can be a gamble, but this two-piece set fit perfectly right out of the package. The blazer hugs the shoulders beautifully, and the pants have a modern, sleek profile without being too restrictive or tight. The floral pattern is exactly what I wanted—bold and eye-catching, yet elegant enough for a formal setting like a wedding, prom, or gala. I received compliments all night long! The fabric feels premium, breathable, and comfortable enough to wear and dance in for hours without losing its shape. For the price, you are getting a high-end look that rivals much more expensive designer tuxedos. If you want to stand out from the crowd in the best way possible, I highly recommend this suit. It is an absolute must-have for any formal wardrobe!
