Decontamination for Laboratory Biosafety

JoVE 10399

Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA


Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization.…
