Product Description
When precision matters in your lab work, neutral aluminum oxide powder from Avantor’s BAKER ANALYZED® line delivers consistent performance. This high-purity reagent-grade alumina is a staple in chromatography, offering excellent adsorption properties for separating and purifying compounds. Whether you’re a student setting up a column or a researcher refining a protocol, this versatile powder ensures reliable results every time.
Unlike acidic or basic alumina variants, the neutral form provides a balanced pH, making it ideal for sensitive applications where sample integrity is critical. Its fine particle size and uniform texture allow for efficient packing in chromatography columns, reducing channeling and improving separation efficiency. Many labs also use it as a catalyst support or desiccant due to its high surface area and stability.
At eqipped, we understand that quality reagents are non-negotiable. That’s why we source this aluminum oxide directly from Avantor, a trusted name in laboratory supplies. Each batch undergoes rigorous testing to meet BAKER ANALYZED® standards, so you can focus on your experiments without worrying about impurities. Need bulk quantities for your institution? Contact us for tailored solutions.
The 500 g pack size strikes a perfect balance—enough for multiple experiments without excessive storage concerns. Store it in a cool, dry place to maintain its adsorption capacity. For best results in chromatography, activate the powder by heating at 150–200°C for 2–4 hours before use, as this removes residual moisture and enhances performance.
From undergraduate labs to advanced research facilities, this neutral alumina powder is a workhorse reagent. Its compatibility with organic solvents and aqueous solutions makes it adaptable across disciplines, from chemistry to environmental science.

FAQs
What is the difference between neutral, acidic, and basic aluminum oxide?
Neutral alumina has a pH of ~7, making it ideal for general separations. Acidic alumina (pH ~4) is treated with acid for separating basic compounds, while basic alumina (pH ~9) is used for acidic compounds. Neutral is the most versatile for routine applications.
How do I activate aluminum oxide for chromatography?
Heat the powder at 150–200°C for 2–4 hours in an oven or muffle furnace. Cool in a desiccator before use. This removes moisture and activates the surface for better adsorption.
Can this alumina be reused?
Yes, but performance may degrade. Regenerate by washing with a suitable solvent (e.g., methanol for organic contaminants), then reactivate by heating. Test with a standard sample before reuse.
What particle size is this aluminum oxide?
The powder typically ranges from 50–200 mesh (75–300 µm), ideal for column chromatography. Exact specifications are provided in the certificate of analysis.
Is this product suitable for flash chromatography?
Yes, but for high-pressure applications, consider a finer mesh size. This grade works well for gravity or low-pressure column chromatography.
