A-3279 Starch Soluble (Ex Potato) (LR Grade)
Smart Lab A-3279 is a Laboratory Reagent (LR) grade soluble starch derived specifically from potatoes. It is a highly refined carbohydrate used in various laboratory settings as a sensitive chemical indicator, particularly for iodine-based titrations and as a biological substrate.
Description
Description
Soluble Starch A-3279 is supplied as a fine, white powder produced from high-quality potato starch to ensure consistent analytical performance. Unlike native starch, this soluble form is specially processed to dissolve more readily in hot water, forming a clearer solution suitable for visual analysis.
As an LR Grade reagent, it is intended for general laboratory use, teaching laboratories, and qualitative testing where the high precision of Analytical Reagent (AR) grade materials is not strictly required.
Main Features
Source-Specific (Ex Potato)
Derived from selected potato starch, providing an optimal amylose-to-amylopectin ratio for sharp and reliable colorimetric responses.
Laboratory Reagent (LR) Grade
An economical yet dependable grade suitable for routine laboratory work, educational experiments, and industrial quality control applications.
Sensitive Iodometric Indicator
Produces a distinct deep-blue complex with iodine in iodometric titrations, with a sharp color disappearance at the endpoint.
Improved Solubility
Specially treated to dissolve efficiently in boiling water, resulting in a clearer solution compared to untreated native starch.
Multi-Purpose Laboratory Use
Widely applied as a thickening agent in biochemical media, a nutrient source for microorganisms, and as a processing aid in selected pharmaceutical preparations.
