Aceto carmine is a staining solution used primarily in microscopy to highlight cellular components. It is a mixture of carmine dye and acetic acid. Here’s an overview of its properties, preparation, and uses:
Properties
- Color: Red to purplish-red.
- Solubility: Soluble in water and ethanol.
- Staining Characteristics: Stains chromatin and cytoplasmic components, providing contrast for better visualization under a microscope.
Preparation
- Ingredients:
- Carmine dye: A natural red dye extracted from the cochineal insect.
- Acetic acid: A colorless liquid organic compound with a pungent smell.
- Procedure:
- Dissolve a specific amount of carmine powder in hot distilled water.
- Add glacial acetic acid to the solution.
- Filter the mixture to remove any undissolved particles.
Description
Uses of Aceto Carmine
1. Cytology
- Chromosome Staining: Aceto carmine is used to stain chromosomes during cell division processes such as mitosis and meiosis. It helps in visualizing the chromosomal structures, making it easier to study their behavior and morphology.
- Karyotyping: The staining highlights the chromosomal patterns and abnormalities, aiding in the identification of genetic disorders.
2. Histology
- Tissue Staining: In histological studies, aceto carmine is used to stain various tissues, helping differentiate between different types of cells and their components. This is particularly useful in examining the structure and function of tissues.
- Cell Component Differentiation: It selectively stains specific cellular components like chromatin, making it easier to distinguish between the nucleus and cytoplasm in cells.
3. Botany
- Plant Cell Studies: Aceto carmine is widely used to stain plant cells, especially root tips, to observe cell division and growth. It is an essential tool for studying the structure and function of plant cells.
- Temporary Mounts: It is used to prepare temporary mounts of plant tissues for microscopic examination, making it easier to study plant anatomy and morphology.
4. Education
- Teaching Tool: In educational settings, aceto carmine is frequently used in biology and botany laboratories to teach students about cell division, tissue structure, and plant anatomy. Its ease of use and effectiveness make it a popular choice for demonstrations and practical exercises.
- Laboratory Practicals: Students use aceto carmine in laboratory practicals to learn staining techniques and to observe cellular structures under the microscope.
5. Research
- Genetic Studies: Researchers use aceto carmine to study chromosomal behavior and abnormalities, contributing to genetic research and understanding of hereditary conditions.
- Developmental Biology: It is used to study the development and differentiation of cells and tissues in both plants and animals, aiding in developmental biology research.

Acetic Acid 2.5litre
Acetic acid is an organic acid with the chemical formula CH3COOH, also known as ethanoic acid. It is a colorless liquid with a pungent, sour taste and a distinctive vinegar-like odor. Acetic acid is an important industrial chemical used in the production of various products, including solvents, plastics, textiles, and food additives. It is also the main component of vinegar, which is commonly used as a condiment and preservative in cooking and food preparation.
Aluminum Ammonium Sulphate
Aluminum ammonium sulfate, also known as ammonium alum or just alum, is a chemical compound with the formula (NH4)Al(SO4)2·12H2O. It's a white crystalline solid commonly used in water purification, leather tanning, and as a mordant in dyeing textiles.
In water purification, alum acts as a coagulant to remove impurities by causing suspended particles to clump together, making it easier for filtration to remove them. In leather tanning, it helps to stabilize the leather by tightening the collagen fibers. And in dyeing textiles, alum helps the dye adhere to the fabric.
However, it's important to note that excessive exposure to aluminum compounds like alum can be harmful, so it's typically used with caution and proper safety measures.
Aluminum Hydroxide 250gm
Aluminium hydroxide is a chemical compound with the formula Al(OH)3. It is an inorganic compound that is commonly used as an antacid to neutralize excess stomach acid, as well as a component in the manufacture of various products, such as ceramics, paper, and cosmetics. It is a white, powdery substance that is insoluble in water and has a low toxicity. When heated, it decomposes to produce aluminium oxide, or alumina, which is used in the production of aluminium metal.
Aluminum Sulphate 500gm
Aluminum sulfate, also known as alum, is a chemical compound with the formula Al2(SO4)3. It's commonly used in water treatment plants as a coagulant to clarify turbid or muddy water by causing suspended particles to clump together and settle out. In addition to water treatment, aluminum sulfate has various other industrial applications, such as in paper manufacturing, dyeing, and as a mordant in textile dyeing to help fix dyes to fabrics.
Ammonia Solution 2.5litres
An ammonia solution is a solution of ammonia (NH3) gas dissolved in water. It is a clear, colorless liquid with a pungent odor and a basic pH. The concentration of ammonia in the solution can vary, and is typically expressed in terms of percent by weight or by volume.
Ammonia solutions are commonly used in a variety of applications, including cleaning agents, fertilizers, and as a precursor to other chemicals. They are also used in industrial processes such as refrigeration, gas purification, and water treatment. Ammonia solutions can be dangerous if not handled properly, as they are highly corrosive and can release toxic fumes if mixed with certain chemicals
