What is the universal disinfectant?

The Power of Chlorine in the Lab

When it comes to keeping laboratory spaces safe and sterile, science relies on a tried-and-true workhorse. Often called the universal disinfectant, chlorine stands out as a powerful agent capable of tackling a wide array of microorganisms, from everyday bacteria to more stubborn pathogens.

In practical laboratory settings, you rarely see pure chlorine gas floating around. Instead, it is most commonly delivered in the form of sodium hypochlorite, which comes packed in varying concentrations of free chlorine depending on the specific cleaning task at hand.

For general, everyday laboratory work and surface sanitation, technicians typically rely on a standard concentration of 1 g/l (1000 ppm) of free chlorine. This specific strength strikes the ideal balance, ensuring surfaces remain thoroughly sanitized without being excessively harsh or difficult to manage during daily routines.
