Description

Dextranomer is a highly cross-linked, hydrophilic polysaccharide bead derived from dextran, widely recognized for its exceptional fluid absorption capacity. This property makes it a critical component in advanced wound care and medical device applications, where effective exudate management is paramount. Key industries that rely on this material include pharmaceutical manufacturing, medical device production, and advanced biomaterial research for developing absorbent matrices and controlled-release systems.

Application

• Advanced Wound Dressings: Primary absorbent component in gels, beads, and pastes for managing moderate to heavily exuding wounds, such as leg ulcers and pressure sores.
• Medical Device Manufacturing: Used in the production of specialized surgical pads, wound packing materials, and other absorbent medical textiles.
• Pharmaceutical Formulations: Serves as a carrier or excipient in topical drug delivery systems, facilitating controlled release of active ingredients.
• Biomaterial Research: Utilized as a model porous matrix or scaffold in laboratory studies for tissue engineering and fluid dynamics.
• Diagnostic Applications: Can be employed in certain diagnostic test kits as an absorbent or separation medium.
• Veterinary Medicine: Applied in wound care products and topical treatments for animals.

Quality Control

Our Dextranomer is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. The product undergoes rigorous testing for critical parameters including particle size distribution, swelling capacity, purity, and absence of pyrogens. Certificates of Analysis (COA) documenting full specifications are provided with each shipment. We can supply material compliant with relevant pharmacopoeial standards (e.g., for medical device applications) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial opening to prevent moisture absorption, which can affect the product's performance.
