They are those tools that allow to obtain a sterile and safe area for any need that is required within a laboratory. They can be: Horizontal and Vertical. Basically, it constitutes a space which, by means of a specific air treatment, allows working in an area with a strict control of non-viral particles.
This type of equipment is used for certain processes where extreme contamination control is required.
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 known or unknown. For these cases there are biological safety cabinets, prepared for the protection of the product / process, the operator and the environment.
