Kieselguhr Adsorbents MACHEREY-NAGEL Celite 545 LC Packing 1kg Bulk

Description

Product Overview

The MACHEREY-NAGEL 815560.1 Kieselguhr Adsorbents are engineered to meet the rigorous demands of modern liquid chromatography laboratories. Formulated from high‑purity Celite 545, this material offers uniform particle size distribution and excellent chemical inertness, making it a reliable choice for packing LC columns where precision and repeatability are essential. The product is supplied in a 1 kg bulk container, providing ample material for multiple column preparations while maintaining consistent performance across batches.

Each kilogram of Kieselguhr is produced under strict quality‑control protocols that monitor moisture content, particle morphology, and bulk density. The resulting packing material exhibits low back‑pressure, enabling faster run times without compromising resolution. Its silica‑based composition resists degradation from a wide range of solvents, acids, and bases commonly used in analytical and preparative chromatography, ensuring long‑term column stability and reduced downtime for column regeneration.</n

Designed for compatibility with a variety of LC column formats, the Celite 545 packing material can be used in both analytical and preparative scale columns, ranging from 2 mm to 10 mm internal diameters. The material’s high mechanical strength supports high‑pressure applications up to 600 bar, allowing users to explore advanced gradient methods and high‑throughput workflows with confidence. Additionally, the bulk packaging minimizes exposure to atmospheric moisture, preserving the adsorbent’s performance characteristics throughout its shelf life.

Packaging dimensions of 11.69 × 5.79 × 5.47 inches and a net weight of 2.2 lb make handling and storage straightforward for laboratory personnel. The product is shipped from the United States, ensuring rapid delivery to North American customers and compliance with regional regulatory standards. Detailed product specifications, including particle size range (30–50 µm) and surface area (approximately 150 m²/g), are provided on the accompanying data sheet to assist users in method development and validation.

Usage

This Kieselguhr adsorbent is ideally suited for laboratories engaged in pharmaceutical analysis, environmental testing, and biochemical research where high‑resolution separation of complex mixtures is required. Its low back‑pressure characteristics enable efficient use in high‑speed LC systems, reducing solvent consumption and operational costs. Researchers can employ the material for both reversed‑phase and normal‑phase chromatography, benefiting from its versatile surface chemistry that supports a broad spectrum of analyte polarities.

In practical terms, the bulk 1 kg supply allows users to pack multiple columns or to replenish existing columns without the need for frequent re‑ordering. This is particularly advantageous for core facilities and contract research organizations that operate a high volume of chromatographic analyses daily. The material’s stability under a wide pH range (2–12) ensures compatibility with diverse mobile phase compositions, making it a flexible component in method development pipelines.

Target audiences include analytical chemists, method developers, and quality‑control technicians who demand reliable, reproducible column performance. The product’s consistent particle size distribution contributes to uniform flow dynamics, which is critical for achieving accurate quantitation and method robustness. By integrating this adsorbent into their workflows, users can achieve sharper peak shapes, improved resolution, and extended column lifetimes, ultimately enhancing overall laboratory productivity.
