It is a clear, colorless, mild oxidizer for laboratory reagent use, microbiology testing, cleaning, and disinfection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat 3% (w\/w) means.\u003c\/strong\u003e Every 100 g of solution contains 3 g of hydrogen peroxide. Stated by weight, as reagent peroxide normally is, it corresponds to roughly 0.9 M and about 10 volumes of available oxygen (calculated).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy stabilized.\u003c\/strong\u003e Hydrogen peroxide slowly decomposes to water and oxygen, and traces of metals, dust, heat, and light speed the process. Stabilizers slow that breakdown, so the solution holds its strength longer between uses, which matters for reagent work that depends on concentration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaboratory uses.\u003c\/strong\u003e Three-percent hydrogen peroxide is used for the catalase test in microbiology, as an oxidizing reagent in sample preparation and teaching experiments, for cleaning and disinfecting surfaces and equipment, and for removing organic stains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight protection.\u003c\/strong\u003e Light accelerates peroxide decomposition. Store the solution in a dark place and keep the container closed to preserve strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize for routine use.\u003c\/strong\u003e The 3.8 L size supports labs that use 3% peroxide daily for testing or cleaning, providing one consistent lot. For smaller volumes, see Lab Pro's Hydrogen Peroxide 3% (500 mL, 1 Gallon).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiluting stronger peroxide.\u003c\/strong\u003e Labs that prefer to prepare 3% in-house dilute 30% hydrogen peroxide about tenfold with deionized water. A stabilized ready-made 3% reagent avoids handling the concentrate and gives consistent strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChecking strength.\u003c\/strong\u003e For critical reagent use, confirm concentration by titration with standardized potassium permanganate in sulfuric acid. Each mole of permanganate reacts with 2.5 moles of hydrogen peroxide.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecomposition products.\u003c\/strong\u003e Hydrogen peroxide breaks down only to water and oxygen, which is why it leaves no persistent residue on cleaned surfaces and is widely used where residues would interfere with later work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling at a glance.\u003c\/strong\u003e Three-percent hydrogen peroxide is mild but can irritate the eyes. Wear safety glasses, avoid eye contact, and rinse splashes with water. Never return used solution to the stock container.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;
