Iodine Tincture Extra Pure
SHORT DESCRIPTION
Iodine Tincture Extra Pure is a high-quality antiseptic solution composed of elemental iodine dissolved in a mixture of alcohol and potassium iodide. It is widely used for disinfecting wounds, sterilizing skin before medical procedures, and as a laboratory reagent in various analytical and microbiological applications. Its fast-acting antimicrobial properties make it effective against bacteria, viruses, and fungi. In laboratory settings, it serves as a reliable indicator and staining agent. Due to its volatility and staining nature, the tincture should be handled with care and stored in tightly closed, amber-colored bottles to preserve stability and prevent degradation.
USES
Primary Laboratory Uses:
- Antiseptic and Disinfectant Studies:
Iodine tincture is commonly used in microbiology labs to study antimicrobial efficacy, particularly in surface sterilization and wound disinfection models. - Biological Staining:
Used as a mordant or contrast agent in microscopic studies, especially for enhancing visibility of cell structures in plant and animal tissues. - Chemical Testing for Starch:
Serves as a quick field reagent for starch detection, where the presence of starch turns the iodine solution deep blue-black.
Secondary Laboratory Uses:
- Iodine Source in Redox Titrations (Iodometry):
May serve as a readily available iodine source in some titration procedures when high-purity iodine is not required. - Educational Demonstrations and Experiments:
Used in science education to demonstrate concepts such as diffusion through membranes, osmosis, or antiseptic action in practical biology and chemistry. - Preparation of Dilute Iodine Solutions:
Acts as a stock solution for preparing various iodine-based reagents used in both analytical chemistry and biochemistry.

SAFETY PRECAUTIONS
Personal Protective Equipment (PPE):
- Wear a lab coat, nitrile gloves, and safety goggles.
- Use in a well-ventilated area or under a fume hood due to volatile solvents.
Handling:
- Avoid skin and eye contact; iodine and alcohol can be irritating.
- Prevent inhalation of vapors.
- Wash hands thoroughly after use.
- Keep away from heat, sparks, open flames, and hot surfaces—no smoking.
Storage:
- Store tightly sealed in a cool, dry, and well-ventilated space.
- Keep away from light, heat, and incompatible substances (e.g. strong oxidizers).
- Flammable—store away from ignition sources.
FIRST AID MEASURES
Inhalation:
- Move the person to fresh air.
- Keep breathing comfortable for breathing.
- Seek medical attention if respiratory irritation occurs.
Skin Contact:
- Immediately wash with soap and water.
- Remove contaminated clothing.
- Seek medical advice if irritation develops or persists.
Eye Contact:
- Rinse carefully with water for several minutes.
- Remove contact lenses if present and easy to do.
- Continue rinsing and seek medical help.
Ingestion:
- Rinse mouth. Do not induce vomiting.
- Never give anything by mouth to an unconscious person.
- Seek immediate medical attention.
FIRE FIGHTING MEASURES
Flammability:
- Highly flammable due to alcohol content.
Extinguishing Media:
- Use CO₂, dry chemical powder, or alcohol-resistant foam.
- Water spray can cool surfaces but may spread flammable liquids.
Hazardous Combustion Products:
- Iodine vapors, carbon monoxide, carbon dioxide, and irritating fumes.
Firefighter Protection:
- Wear full protective clothing and self-contained breathing apparatus (SCBA).
- Evacuate the area and fight fire from a safe distance.
