It is a clear, colorless, mild oxidizer used for cleaning, disinfection, and laboratory reagent applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat 3% delivers.\u003c\/strong\u003e A 3% solution contains about 30 g of H2O2 per liter (roughly 0.9 M) and is often described as 10 volume, meaning it can release about 10 volumes of oxygen upon complete decomposition (calculated). That strength works for many cleaning and disinfecting tasks while being far safer to handle than concentrated peroxide.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow it works.\u003c\/strong\u003e Hydrogen peroxide releases reactive oxygen species that oxidize organic matter, break down stains, and inactivate microorganisms. It decomposes to water and oxygen, leaving no persistent residue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaboratory uses.\u003c\/strong\u003e In the lab, 3% hydrogen peroxide is used for the catalase test in microbiology, where bubbling indicates catalase-producing organisms; for cleaning and disinfecting benches and equipment; for removing organic stains; and as an oxidizing reagent in teaching experiments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStability.\u003c\/strong\u003e Even dilute peroxide slowly decomposes, especially when exposed to light, heat, metals, or contamination. Keep the container closed and in a cool, dark place, and replace stock that no longer fizzes vigorously on contact with a catalase-positive organism or a drop of blood.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo sizes.\u003c\/strong\u003e The 500 mL size (HP6300-500) suits benchtop use and teaching labs, while the 1 gallon size (HP6300-38) supports routine cleaning and higher-volume reagent use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe catalase test in detail.\u003c\/strong\u003e To perform the test, place a small amount of colony on a slide and add a drop of 3% hydrogen peroxide. Immediate bubbling shows catalase activity, which helps classify bacterial isolates in microbiology.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling.\u003c\/strong\u003e Three-percent hydrogen peroxide is mild but can irritate eyes. Wear safety glasses, avoid eye contact, and rinse splashes with water. For stronger solutions, see Lab Pro's Hydrogen Peroxide 6%, 1 Gallon and Hydrogen Peroxide 30 to 32%, 1 Pint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhere it is used.\u003c\/strong\u003e Three-percent hydrogen peroxide is used in microbiology labs, teaching labs, cleanrooms and general surface cleaning, equipment and electronics cleaning, and as a mild oxidizer in sample preparation and demonstrations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%;
