Aluminium Oxide Active Neutral Extra Pure is a high-purity, fine white powder known for its high surface area and neutral pH, making it ideal for chromatography, adsorption, and catalyst support in laboratory research. Its active form ensures excellent capacity for separating and purifying organic compounds without altering their chemical structure, especially in column chromatography applications. Commonly used in analytical, organic synthesis, and material science laboratories, it provides consistent performance in adsorption studies, drying of solvents, and reaction monitoring. The extra pure grade ensures extremely low levels of impurities, suitable for high-precision experimental work. To maintain its activity, it should be stored in airtight containers away from moisture and reactive chemicals.

Ammonium Carbonate Extra Pure is a high-quality, white crystalline solid widely used across various scientific, industrial, and food-related applications. Manufactured to stringent purity standards, this compound is ideal for laboratories and processes that demand high-grade reagents. With its characteristic ammonia-like odor and ability to decompose upon heating, ammonium carbonate plays a versatile role in both chemical reactions and physical processes.
In aqueous solution, ammonium carbonate breaks down into ammonium bicarbonate and ammonium carbamate, further releasing ammonia (NH₃) and carbon dioxide (CO₂) upon heating. This property makes it especially useful in applications that require controlled gas release or temporary pH modification.
