Description

Amberlite XAD-7 is a macroreticular, cross-linked acrylic ester adsorbent resin widely used for the purification and separation of organic compounds from aqueous and non-aqueous solutions. Its importance lies in its excellent chemical stability and high surface area, which enables efficient adsorption of a wide range of medium-polarity molecules. This product is essential for industries requiring advanced separation techniques, including pharmaceutical manufacturing, environmental remediation, and the recovery of valuable natural products.

Application

• Pharmaceutical Purification: Adsorption and purification of antibiotics, steroids, and other active pharmaceutical ingredients (APIs) from fermentation broths or reaction mixtures.
• Wastewater Treatment: Removal of organic pollutants, phenols, and dyes from industrial wastewater streams.
• Natural Product Extraction: Isolation and concentration of flavonoids, alkaloids, and pigments from plant extracts.
• Food & Beverage Processing: Decolorization of sugar syrups and removal of off-flavors or impurities.
• Chemical Synthesis: Separation of reaction products or catalysts in organic synthesis processes.
• Analytical Sample Preparation: Solid-phase extraction (SPE) for the preconcentration of analytes prior to HPLC or GC analysis.

Quality Control

Our Amberlite XAD-7 is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance characteristics such as surface area, pore volume, and particle size distribution. A Certificate of Analysis (COA) detailing the physical and chemical specifications is provided with every shipment to guarantee it meets the requirements for your specific application.

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). Keep away from strong oxidizing agents. The resin should be kept moist as supplied; if dried, it must be rehydrated carefully before use to prevent cracking.
