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.

Description

USES

Table of Contents

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 HANDLING PRECAUTIONS

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.
