Sudan III (Animal Tissue)
Sudan III (Animal Tissue) (Product Code: SCL458/0140) is a fat-soluble dye used to show lipids by staining fat droplets orange-red in animal tissue preparations and food tests. Biology and physiology classes rely on it because it dissolves far more readily in fats and oils than in water, and it is packed as 125 ml of analytical reagent grade stain with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a biology lab equipment supplier serving schools and colleges.

What Is Sudan III Stain Used For?
For the food test, a little oil, butter or crushed food is shaken with water in a test tube and a few drops of Sudan III are added. After standing, any lipid collects as a red-stained oily layer at the surface, while a lipid-free sample leaves the colour evenly spread. In histology and physiology classes the stain is applied to fresh or frozen preparations of animal tissue, where it picks out fat droplets inside cells; routine alcohol-processed permanent sections generally lose their fat, so fresh material gives the clearest result.
Wear gloves, keep the container firmly closed and store it away from heat and open flames; the MSDS supplied with the reagent sets out storage, handling and disposal. Schools stocking school biology lab equipment in India often order Sudan III together with the sugar and protein test reagents, so the full food-test practical can run from one consignment.
Supplier
ScienceLab is the brand name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, which supplies stains, reagents and apparatus to teaching and research laboratories in India and international markets.

Frequently Asked Questions
What does Sudan III (Animal Tissue) stain?
Sudan III (Animal Tissue) colours lipids such as fats and oils orange-red. Proteins and carbohydrates are not stained, which is why it is used as a specific test for fat in food samples and for fat droplets in fresh animal tissue.
How much Sudan III (Animal Tissue) is supplied?
Each container of Sudan III (Animal Tissue) holds 125 ml of analytical reagent grade stain and is supplied with an MSDS. A few drops are enough for each food test, so one container serves many student groups through the year.
Can Sudan III (Animal Tissue) be used on permanent animal tissue slides?
Usually not. Routine processing for permanent slides uses alcohol and clearing agents that dissolve fat, so Sudan III (Animal Tissue) works best on fresh or frozen tissue preparations where the lipid droplets are still present.
What is the shelf life of Sudan III (Animal Tissue)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for Sudan III (Animal Tissue). Ask us for the expiry date of the batch you are quoted, and store it closed, cool and away from light and open flames.
Who supplies Sudan III (Animal Tissue)?
Sudan III (Animal Tissue) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company can quote it with Benedict's and biuret reagents, so a complete food-test practical for carbohydrates, proteins and lipids can be ordered together.
What should an institutional quotation request include?
A quotation request for Sudan III (Animal Tissue) should list the product name and code SCL458/0140, the quantity, the delivery address and any documents your purchase process needs. Send these through the contact page for a quotation covering India or international delivery.
