Product Overview
The Molecular Sieve, Activated, Type 3A BAKER ANALYZED™ Reagent is a high-performance desiccant engineered for precision moisture control in laboratory settings. With a pore size of 3Å, this activated molecular sieve selectively adsorbs water molecules while excluding larger compounds, ensuring efficient drying of gases and liquids. Its uniform bead form maximizes surface area for superior adsorption capacity, making it indispensable for applications requiring stringent moisture removal, such as solvent purification and gas stream dehydration. The reagent-grade purity guarantees minimal impurities, reducing interference in sensitive analytical processes. Designed for reliability, this molecular sieve maintains structural integrity under thermal regeneration, allowing for repeated use without compromising performance. Its compatibility with a wide range of solvents and gases further enhances its versatility in lab workflows. Whether used in static or dynamic systems, this 3A molecular sieve delivers consistent results, safeguarding equipment and experiments from moisture-induced degradation. The 500 g pack size offers ample quantity for frequent use, balancing cost-efficiency with convenience for researchers and technicians.
FAQs
1. What is the pore size of this molecular sieve and why does it matter?
The pore size is 3Å, which allows it to selectively adsorb water molecules while excluding larger compounds. This specificity is critical for applications where only moisture needs to be removed without affecting other components in the system.
2. Can this molecular sieve be regenerated after use?
Yes, it can be thermally regenerated by heating to 200–300°C to remove adsorbed moisture, restoring its adsorption capacity for repeated use. Ensure gradual heating to avoid thermal shock.
3. Is this molecular sieve compatible with organic solvents?
It is compatible with most organic solvents, but avoid prolonged exposure to highly polar or reactive solvents, as they may degrade the sieve’s structure or reduce its effectiveness.
4. How should this molecular sieve be stored to maintain its performance?
Store in a tightly sealed container in a dry, cool environment to prevent premature moisture adsorption. Avoid exposure to open air for extended periods before use.
5. What alternatives exist if a larger pore size is required?
For applications requiring adsorption of larger molecules, consider Type 4A or 5A molecular sieves, which have pore sizes of 4Å and 5Å, respectively, but may also adsorb smaller molecules like CO₂.
