Not all molecular sieves are created equal, and you want to be sure to get the one that is right for your needs. Read on to find out more about what a sieve does and what the various sizes offer! What is a Molecular Sieve? A molecular sieve, also called a mole sieve, is a type of drying agent that …

A molecular sieve is a porous material that has very small, uniform-sized holes. It works like a kitchen sieve, except on a molecular scale, separating gas mixtures that contain multi-sized molecules. Only molecules smaller than the pores can pass through; whereas, larger molecules are blocked. If the molecules you want to separate are the same size, a molecular sieve can …

Molecular Sieves are available in: 3A Molecular Sieve 3A means that the pore size measures as 3 angstrom. Anything larger than 3 angstrom won’t be able to be adsorbed. The order of adsorption rate is helium, neon, nitrogen and water. 3A EDG Molecular Sieve This Molecular Sieve was made with drying fuel grade ethanol in mind. Ethanol can only be …

Molecular Sieve Desiccants are typically used for drying gases and liquids. They are made up of a crystalline composition which makes them even more effective than other types of desiccants. These sieves are extremely helpful in cryogenic operations, during this process all water must be removed to avoid freezing. Molecular Sieves come in multiple ranges of absorbency, along with molecule shape and sieve surface. …

Zeolites as an adsorbent Zeolites are inert and extremely durable; they can withstand elevated temperatures, heavy loads, will remain free-flowing immersed in water, and will not disintegrate when exposed to air. Zeolites are commonly applied as an adsorbent because of its construction and due to their ability to be regenerated over and over again for re-use; many times designed to …

These instructions are meant for indicating (blue or orange) product only, it is difficult to effectively gauge if colorless product has re-generated. Let’s begin with some safety precautions: Use a Pyrex baking dish which is at least a ¼“ thick, the product becomes very hot while drying and potentially can cause other types of glass to shatter. It is also recommended not to …
