Bleach is commonly used in the laboratory as a disinfectant to kill bacteria, viruses, and other microorganisms on surfaces and equipment. It is also used for sterilization of laboratory equipment like glassware, pipettes, and plasticware. Additionally, bleach is used for decontamination of laboratory spills and for the treatment of wastewater.
Bleach, which typically refers to a solution of sodium hypochlorite (NaClO) or calcium hypochlorite (Ca(ClO)2), has various functions in the laboratory due to its oxidizing and disinfecting properties. Here are some common functions of bleach in the laboratory:
1. Disinfection: Bleach is commonly used as a disinfectant in the laboratory. It can kill or deactivate a wide range of microorganisms, including bacteria, viruses, and fungi. It is often used to clean laboratory surfaces, equipment, and biological safety cabinets.
2. Sterilization: In certain cases, bleach can be used for sterilization purposes. It can help eliminate or reduce microbial contamination on laboratory glassware, such as petri dishes, test tubes, and pipettes.
3. Decontamination: Bleach is effective in decontaminating laboratory materials that may be contaminated with biological or chemical agents. It can neutralize or destroy hazardous substances, reducing the risk of contamination or cross-contamination.
4. DNA/RNA Extraction: In molecular biology and genetics laboratories, bleach can be used to sterilize tools and equipment used in DNA/RNA extraction processes. It helps minimize the presence of contaminants that may interfere with the analysis of genetic material.
5. Spill Cleanup: In the event of a spill involving biological materials or certain chemicals, bleach can be used to decontaminate the spill area. It helps in disinfecting and minimizing the potential spread of hazardous substances.
6. Water Treatment: In environmental and water testing laboratories, bleach can be used to treat water samples for disinfection. It helps eliminate or reduce the presence of microorganisms that may interfere with water quality analysis.
It's important to follow proper safety protocols when using bleach in the laboratory, including wearing appropriate protective equipment, ensuring proper ventilation, and adhering to the recommended dilution ratios.

Bleach, which is a solution of sodium hypochlorite (NaClO), has several functions in the laboratory. It is commonly used as a disinfectant to kill bacteria, viruses, and other microorganisms on surfaces and equipment. It can also be used to oxidize or bleach certain organic compounds in chemical reactions. Additionally, bleach can be used to remove stains or disinfect laboratory clothing, gloves, and other protective gear. However, it's important to use bleach carefully and follow safety guidelines since it can be corrosive and toxic if not handled properly.
