Aluminum Oxide Adsorbents 815010.1 MACHEREY-NAGEL Bulk Basic 1kg

Description

Product Overview

The MACHEREY‑NAGEL 815010.1 aluminum oxide adsorbents are engineered for high‑performance column chromatography in both research and production environments. Each kilogram of material is supplied in a bulk, moisture‑controlled container that preserves the integrity of the particles, which range from 50 µm to 200 µm in size. The adsorbent exhibits a specific surface area of approximately 130 m²/g as measured by BET analysis, providing ample active sites for interaction with a wide variety of analytes. The material is available in neutral, basic, and acidic forms, with the basic grade being the focus of this listing, ensuring compatibility with a broad spectrum of mobile phases and buffer systems. The product complies with rigorous quality standards set by MACHEREY‑NAGEL, a globally recognized manufacturer of chromatography media, and is listed under model 815010.1 for precise identification.

In addition to its high surface area, the adsorbent’s particle size distribution is tightly controlled to promote uniform flow and reduce back‑pressure in packed columns. The bulk format eliminates the need for frequent re‑ordering, making it a cost‑effective solution for laboratories that run high‑throughput separations. The packaging dimensions of 12 × 12 × 12 inches and a weight of 2.2 lb facilitate easy handling and storage while protecting the material from ambient humidity. The product’s ASIN (B07T24QWVK) and its ranking as #22 in the Lab Chromatography LC Columns & Column Supplies category underscore its relevance and popularity among scientific professionals.

Usage

This aluminum oxide adsorbent is ideally suited for a range of chromatographic techniques, including normal‑phase, reverse‑phase, and ion‑exchange separations. Researchers can employ it for the purification of small molecules, peptides, and natural products, as well as for the removal of impurities in complex mixtures. The basic grade excels in applications where a higher pH environment is required, such as the separation of basic compounds or the removal of acidic contaminants. Its robust particle size and surface characteristics enable consistent performance across multiple runs, reducing variability and improving reproducibility in analytical workflows.

Industrial users can also leverage the bulk quantity for preparative scale separations, where the high loading capacity and low back‑pressure contribute to efficient processing of large sample volumes. The adsorbent’s compatibility with a variety of solvents—including methanol, acetonitrile, dichloromethane, and water—allows flexibility in method development and optimization. Whether used in manual column packing or automated chromatography systems, the material delivers reliable performance, making it a versatile choice for both discovery‑phase research and large‑scale production.

FAQ

What is the recommended column packing pressure for this adsorbent?

The recommended packing pressure is typically between 5 and 10 bar, depending on column dimensions and the desired flow rate. Maintaining this pressure range helps achieve a homogeneous bed and consistent chromatographic performance.

Can this adsorbent be used with aqueous mobile phases?

Yes, the basic grade of the aluminum oxide adsorbent is compatible with aqueous solvents and can be employed in methods that require high‑pH buffers or water‑rich mobile phases without compromising stability.

How should the bulk material be stored to maintain its performance?

Store the bulk container in a cool, dry environment away from direct sunlight. The packaging includes a moisture‑absorbing desiccant to protect the adsorbent from humidity, preserving its surface area and particle integrity.

Is the adsorbent suitable for preparative scale chromatography?

Absolutely. The 1 kg bulk quantity provides sufficient material for preparative runs, and the high loading capacity combined with low back‑pressure makes it an efficient choice for large‑scale separations.
