In laboratories, starch can act as an indicator, thickening agent, technical excipient, or component of physicochemical assays. Proper selection depends on the purpose, product specification, and technical documentation that accompanies the batch.
Laboratory applications of starch
Starch is frequently used in iodometry and iodimetry procedures, in which it reacts with iodine and forms a characteristic color. This visual response helps identify the titration endpoint, provided the solution is prepared according to the required analytical method.
It can also be used in viscosity tests, stability studies, experimental formulations, and comparative analyses of raw materials. That is why technical use of starch requires control over concentration, solubilization, storage, and compatibility with other reagents.
How to evaluate starch before purchase?
Buying starch for laboratory purposes must consider criteria beyond price. In analytical processes, small quality variations can compromise results, cause rework, and hinder analysis traceability.
Some aspects help qualify the choice:
- Product technical specification: allows verification that the starch meets the intended method or application.
- Batch certificate and documentation: support traceability, internal checking, and quality control.
- Packaging conditions: reduce risks of moisture, contamination, and physical change.
- Technical support in supply: helps selection according to use, concentration, and laboratory routine.
Storage and handling precautions
Starch should be kept in a dry, airy place protected from excessive heat. Packaging must remain tightly closed after use, since moisture exposure can alter the powder appearance and impair its application.
During handling, follow the safety data sheet and internal laboratory procedures. Weighing, transfer, and solution preparation should use clean utensils, avoiding cross-contamination.
