Most people in the United States dilute 30% hydrogen peroxide before using it for cleaning and disinfecting operations. It must be handled carefully during the process of dilution because it is severely corrosive to your eyes, skin and respiratory tract. 30% hydrogen peroxide is used in laboratories to prepare solutions for inducing apoptosis in CHO K1 cell lines. Hydrogen peroxide diluted solutions (30% wt in water) are used in laboratories in the USA as a powerful oxidant and reducing agent. It is stored in a refrigerator and should be handled nitrile gloves, safety goggles and a labcoat. The molarity of a 30 % hydrogen peroxide solution is 9.8 M based on a density of 1.11 g/ml. 30% hydrogen peroxide is 30% w/v of hydrogen peroxide for each 100 mL of solution there are 30 g of hydrogen peroxide. 30% hydrogen peroxide is used as a reagent in laboratories in the USA. In laboratories in America, 30 wt% solutions of hydrogen peroxide are the most commonly used.
Most laboratory chemicals are labelled with a grade which generally indicates the purity of the chemical. Laboratory grade 30% hydrogen peroxide is the most popular grade for use in educational applications, but its exact levels of impurities are unknown. While excellent for teaching and training, it is not pure enough to be offered for food, drug, or medicinal use of any kind. In general, technical grade or laboratory grade 30% hydrogen peroxide has the lowest purity. Laboratory Grade chemicals are often used in less critical analyses and educational labs and school science laboratories as a middle tier quality.
30% Hydrogen Peroxideis a clear, colorless liquid that is classified as a strong oxidizer and a corrosive liquid. It is commonly used as a laboratory reagent and also in its vapor form as a sterilizer, a popular alternative to ethylene oxide and formaldehyde, as a safer and more efficient decontamination method for isolated rooms and biosafety cabinets.
