Phosphotungstic Acid LR/AR is a chemical compound which is most commonly utilized as a homogenous catalyst for various reactions.Phosphotungstic Acid LR/AR appears as white to yellowish green crystalline powder with a melting point of about 89 degrees Celsius.

Phosphoric acid is stronger than acetic acid, so it is ionized to a greater extent. Acetic acid is stronger than carbonic acid, and so on.

 Mesh Size (or U.S. Sieve Size) is defined as the number of openings in one square inch of a screen. For example, a 36 mesh screen will have 36 openings while a 150 mesh screen will have 150 openings. ... For example, a product identified as -100 mesh would contain only particles that passed through a 100 mesh screen.

The CERTISTAIN dry dye Phloxin B (C.I. 45410) is used for the preparation of a staining solution for cytoplasmic staining in histological sections of human origin. It is mainly used in Hemytoxylin and Eosin (H&E) overview staining that is routinely performed in histological laboratories.

Primuline is used as a reagent in the preparation of lipids for chloroplast lipid membrane. 

It is also used as a dye in preparative thin-layer chromatography (TLC).

 Primuline is suitable for vital staining and is used as a fluorochrome in plant tissues

Potassium Nitrate is a crystalline salt, KNO3; a strong oxidizer used especially in making gunpowder, as a fertilizer, and in medicine.

Potassium nitrate can be made by combining ammonium nitrate and potassium hydroxide. Potassium nitrate can also be produced by neutralizing nitric acid with potassium hydroxide. This reaction is highly exothermic

Ruthenium red is a polycationic stain used to visualize acid polysaccharides on the outer surface of cells. Ruthenium red staining followed by electron microscopic analysis was used to demonstrate the presence of an external glycoprotein layer surrounding the spore of both Bacillus anthracis and Bacillus subtilis.

Polyvinylpyrrolidone, also known as povidone or PVP, is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs.N-vinyl-2-pyrrolidone (VP) is commonly used as a reactive diluent for radiation curing in UV-coating, UV-inks, and UV- adhesives.

Phthalide is an organic chemical compound with the molecular formula C8H6O2. It is a lactone that serves as the core chemical structure for a variety of more complex chemical compounds including dyes (such as phenolphthalein), fungicides (such as tetrachlorophthalide, often referred to simply as "phthalide"), and natural oils (such as butylphthalide).

Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid.

Quinaldine or 2-methylquinoline is an organic compound with the formula CH3C9H6N. It is one of the methyl derivative of a heterocyclic compound quinoline. It is bioactive and is used in the preparation of various dyes. It is a colorless oil but commercial samples can appear colored.[1]
