BioSafety Cabinets
Biological safety cabinets are divided into three classes based on the amount of protection they provide.
Class I: The investigator is partially protected, no protection for the sample.
Class II: The investigator is partially protected and the sample is protected.
Class III: Both the sample and the investigator are protected.
