Dextrine White / Yellow – 500 gram Packs

Dextrine White / Yellow, commonly known as Dextrin, is a starch-derived carbohydrate material produced by the partial breakdown or heat treatment of starch. It consists of shorter carbohydrate chains containing glucose units connected primarily through glycosidic bonds. White and yellow dextrins differ in colour and processing characteristics, which can influence their solubility, viscosity, and binding behaviour. This material is relevant to laboratory studies involving carbohydrate chemistry, starch modification, polymeric materials, and aqueous dispersions. Its composition and molecular weight vary according to the source starch and degree of polymerisation, so dextrin is represented by a general chemical formula rather than one fixed molecular structure. Dextrine White / Yellow is suitable for appropriate educational experiments, material science investigations, and research procedures when its properties meet the method requirements. Lab Wale offers this material in convenient 500 gram packs for laboratory and institutional sourcing.

Key Features of Dextrine White / Yellow

• Starch-derived composition: Dextrin contains glucose-based carbohydrate chains formed through the partial breakdown or thermal processing of starch.
• Distinct colour variants: White and yellow dextrins have different processing characteristics and appearances, making variant selection important for specific laboratory procedures.
• Variable molecular weight: The molecular weight depends on the distribution and length of the carbohydrate chains rather than a single fixed molecular structure.
• Useful physical properties: Depending on the variant, dextrin exhibits characteristic water-dispersion, solubility, viscosity, and binding behaviour.
• Research relevance: Its carbohydrate structure and material properties make it suitable for selected investigations in polymer chemistry, starch modification, and materials science.

Laboratory Applications of Dextrine White / Yellow

• Educational chemistry experiments: Used in supervised college and university practicals examining starch-derived carbohydrates and their physical properties.
• Carbohydrate chemistry investigations: Supports studies of starch breakdown, carbohydrate structure, and changes resulting from thermal or chemical processing.

Frequently Asked Questions About Dextrine White / Yellow

What is Dextrine White / Yellow used for in laboratories?

Dextrin is used in carbohydrate chemistry experiments, starch modification studies, solubility investigations, and selected materials research. Its binding and dispersion properties may also be examined in technical formulation studies. The appropriate application depends on the particular dextrin variant and the specifications required by the experimental method.

What is the chemical formula of Dextrin?

Dextrin is commonly represented by the general formula (C₆H₁₀O₅)ₙ. The value of n varies according to the length of the carbohydrate chains. C₆H₁₀O₅ represents the repeating anhydroglucose-unit composition and is not the complete molecular formula of every dextrin molecule.

What is the CAS number of Dextrine White / Yellow?

The CAS Registry Number commonly associated with dextrin is 9004-53-9. This identifier applies to the general dextrin material. Since white and yellow variants can differ in processing and functional properties, confirm the specific product identity when a laboratory method requires a particular type.

What is the difference between White Dextrin and Yellow Dextrin?

White and yellow dextrins differ mainly in their processing conditions, colour, and certain functional characteristics. These differences can influence solubility, viscosity, and binding behaviour. The appropriate variant should be selected according to the experimental purpose, as the two types may not be interchangeable in every laboratory procedure.

How should Dextrine White / Yellow be stored and handled?

Store dextrin in a tightly closed container in a cool, dry location, protected from moisture, excessive heat, and contamination. Avoid unnecessary dust generation and use suitable eye protection and gloves during handling. Keep it away from incompatible substances, particularly strong oxidising agents, and follow the applicable Safety Data Sheet and laboratory procedures.

Storage Conditions for Dextrine White / Yellow

Store Dextrine White / Yellow in a tightly closed, compatible container in a cool, dry, well-ventilated area. Protect it from moisture, excessive heat, and contamination. Keep the material away from incompatible substances, particularly strong oxidising agents, and maintain clean, dry storage conditions. Follow the supplier’s recommendations for the specific variant and ensure the container is properly labelled after use.

Precautions for Handling Dextrine White / Yellow

Review the applicable Safety Data Sheet before use and wear suitable protective gloves, safety goggles, and laboratory clothing. Minimise airborne dust and avoid unnecessary inhalation when transferring or weighing the powder. Use appropriate ventilation when dust may be generated, and prevent contact with incompatible chemicals. Clean spills using methods that limit dust dispersal and dispose of residues according to institutional procedures and applicable local requirements.
