Description

Spherosil is a high-performance, porous silica-based material widely recognized for its exceptional adsorption and chromatographic properties. Its value lies in providing consistent, high-purity separation and purification essential for demanding industrial and pharmaceutical processes. This product is critical for manufacturers and research facilities in the pharmaceutical, biotechnology, and fine chemical sectors who require reliable media for filtration, chromatography, and catalyst support applications.

Application

• Chromatographic Separation: Used as a stationary phase in high-performance liquid chromatography (HPLC) and preparative chromatography for the purification of pharmaceuticals, natural products, and peptides.
• Catalyst Support: Serves as an inert, high-surface-area carrier for catalysts in various chemical synthesis and petrochemical processes.
• Protein & Biomolecule Purification: Employed in affinity and size-exclusion chromatography for the isolation and purification of proteins, enzymes, and other sensitive biomolecules.
• Filtration Media: Acts as a depth filter aid or adsorbent in process streams to remove impurities, color bodies, and particulates.
• Drying Agent: Utilized for drying solvents and gases due to its controlled pore structure and high moisture affinity.
• Analytical Sample Preparation: Used in solid-phase extraction (SPE) cartridges for the clean-up and concentration of analytes prior to analysis.

Quality Control

Our Spherosil is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including particle size distribution, pore volume, surface area, and pH to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture uptake, which can affect performance.
