Product Overview

DEXTRINE WHITE is a refined, water-soluble polysaccharide derived from starch, widely used in laboratories and industries as a binding agent, adhesive, and mounting medium. Its neutral pH and inert nature make it ideal for preparing temporary microscope slides, where it provides a clear, non-reactive background for specimen observation. In pharmaceutical and chemical industries, dextrine serves as a binder in tablet formulation and granule production, ensuring uniform particle cohesion without altering the chemical properties of active ingredients. The powder dissolves readily in cold water, forming a viscous solution that dries to a transparent, glossy film, offering excellent adhesion to glass, paper, and other surfaces. Unlike synthetic adhesives, dextrine is non-toxic and biodegradable, making it a safer choice for educational and research environments. Its stability under moderate temperatures and resistance to microbial growth further enhance its utility in long-term storage applications. Whether used for slide preparation, industrial bonding, or as a filler in pyrotechnics, this laboratory-grade dextrine delivers consistent performance with minimal batch-to-batch variation.

FAQs

1. How do I prepare a dextrine solution for microscopy?

Dissolve 10–20 g of dextrine in 100 ml of distilled water, heat gently if needed, and stir until fully dissolved. Filter before use.

2. Can dextrine be used as a food-grade adhesive?

While generally non-toxic, this lab-grade dextrine is not certified for food use; food-grade alternatives should be sourced for edible applications.

3. What is the drying time for dextrine-based adhesives?

Drying time varies with humidity and thickness but typically ranges from 30 minutes to 2 hours for thin layers.

4. Does dextrine react with common lab solvents?

It is insoluble in organic solvents like ethanol or acetone but soluble in water and glycerol-based mixtures.

5. What is the difference between white dextrine and yellow dextrine?

White dextrine is more refined, with higher solubility and lower color, while yellow dextrine has slightly higher viscosity and residual starch content.
