Laminar flow hoods
This type of equipment is used for certain processes where extreme contamination control is needed.
Normally, these systems are used for microbiological control procedures, packaging process, sterile filling, etc. but in no way should they be used for processes involving strains of contaminating biological agents, whether they are known or not. For these cases there are biological safety cabinets, prepared for the protection of the product / process, the operator and the environment.
