The laminar flow hood first appeared in the field of science, where a guarantee of the microbiological purity of samples was required to perform experiments without risk of cross-contamination. As the laminar flow hood expanded its use, hospitals, clinics and other medical centers recognized its benefits for safe and effective sample handling. For example, it is used to perform DNA extraction, ECyM and PCR in clinical laboratories.
The laminar flow hood also ensures the quality of clinical results by minimizing exposure to cross-contamination. This is achieved by preventing microorganisms from coming into contact with the sample and becoming contaminated, thus reducing the possibility of erroneous or inconsistent results at the clinical level. In addition, the chamber design ensures that laboratory personnel are protected from the possible harmful effects of the chemical or microbiological solvent.
