Product Overview
The 4A molecular sieve is a highly effective desiccant designed for laboratory applications requiring precise moisture control. Composed of sodium aluminosilicate, this molecular sieve features a uniform pore size of 4 angstroms, making it ideal for adsorbing water, ammonia, methanol, and other small polar molecules. The 3 mm bead form ensures optimal flow dynamics and minimal pressure drop in gas or liquid systems. Its high adsorption capacity and thermal stability allow for repeated regeneration cycles without significant degradation in performance. This lab-grade molecular sieve is particularly suited for drying solvents, gases, and air streams where low moisture content is critical. The material is chemically inert and non-corrosive, ensuring compatibility with a wide range of laboratory equipment and processes. Whether used in static or dynamic systems, the 4A molecular sieve delivers consistent performance, making it a reliable choice for researchers and technicians who demand precision in their experimental setups.
FAQs
1. What is the adsorption capacity of this 4A molecular sieve?
The adsorption capacity depends on the specific application and conditions, but under standard laboratory conditions, it can adsorb up to 20-25% of its weight in water.
2. Can this molecular sieve be regenerated, and if so, how?
Yes, the 4A molecular sieve can be regenerated by heating it to 200-300°C in a controlled environment, such as an oven or furnace, to remove adsorbed moisture.
3. Is this molecular sieve compatible with organic solvents?
Yes, it is compatible with most organic solvents, but it is primarily used for drying them rather than reacting with them.
4. What is the shelf life of this molecular sieve when stored properly?
When stored in a dry, airtight container, the shelf life is typically 2-3 years without significant degradation in performance.
5. How does the 3 mm bead size compare to other sizes in terms of performance?
The 3 mm bead size offers a balance between flow dynamics and adsorption efficiency, making it suitable for both static and dynamic applications.
