Field Stain A and B 25gm
Field Stain A and B are used in a staining technique for blood films, particularly for the rapid identification of malaria parasites and other hematological purposes. The staining method is known as Field's stain, and it is a type of Romanowsky stain.
Field Stain A
- Composition: Field Stain A is typically an aqueous solution of methylene blue, which stains the nuclei of cells blue.
- Function: It primarily stains the acidic components of the cell, including DNA and RNA. This makes the nuclei and certain cytoplasmic components appear blue.
Field Stain B
- Composition: Field Stain B is usually an aqueous solution of eosin, which stains the basic components of the cell pink.
- Function: It stains the cytoplasm and extracellular components pink to red. Eosinophilic structures, such as red blood cells and certain granules, are highlighted by this stain.
Usage
- Procedure:
- Prepare the blood smear: A drop of blood is spread thinly on a glass slide and allowed to air dry.
- Apply Field Stain A: The dried smear is immersed in Field Stain A for a short duration, typically around 5-10 seconds.
- Rinse: The slide is briefly rinsed in water to remove excess stain.
- Apply Field Stain B: The smear is then immersed in Field Stain B for another short duration, around 5-10 seconds.
- Rinse and dry: The slide is rinsed again in water and allowed to air dry.
- Outcome: The resulting stained smear allows for the differentiation of various cell components, making it easier to identify and analyze blood cells and any parasitic infections like malaria.
Formaldehyde 2.5 litres (formalin)
Formaldehyde is a colorless gas with a pungent odor, which is used as a disinfectant, preservative, and in the production of various materials and chemicals.
Formalin is a solution of formaldehyde gas in water, typically containing 37% formaldehyde by volume. It is commonly used as a tissue preservative in biological specimens for medical and research purposes. Formalin is also used in various industrial applications such as manufacturing plastics, resins, and textiles.
Formic Acid 2.5l
Formic acid is a colorless, pungent liquid with a chemical formula of HCOOH. It is the simplest carboxylic acid, naturally occurring in certain fruits and vegetables and in the venom of some ants. It has a wide range of industrial applications as a preservative, antibacterial agent, solvent, and in the production of textiles, leather, rubber, and other materials. It also has some medical applications and is used in organic chemistry reactions as a reducing agent. However, formic acid is highly corrosive and can be dangerous if ingested or inhaled in large quantities.
Giemsa Stain Powder 25gm
Giemsa stain powder is a violet-colored biological stain composed of methylene blue, eosin, and azure dyes. It is primarily used in laboratories for staining biological samples such as blood films, bone marrow, and various microorganisms. The stain works by binding to different cellular components, allowing for enhanced visualization and characterization under a microscope. Giemsa stain is particularly valued for its ability to highlight details in cellular structures and to differentiate between different cell types and pathogens.
Glacial Acetic Acid Food Grade 35kg
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.
Glycerol AR 2.5 liters
Glycerin, also known as glycerol, is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. It is a type of alcohol with three hydroxyl (OH) groups, and is commonly used in various industries such as pharmaceuticals, cosmetics, food, and personal care products. Glycerin has numerous applications, including as a solvent, humectant, emollient, and lubricant, among others. It can be derived from both plant and animal sources, and is also produced as a byproduct of soap and biodiesel manufacturing.
