Human Body Filtration Process

BSCs of this class are either ______ (connected to the building exhaust system) or unducted (recirculating filtered exhaust back into the laboratory)

Class II cabinets provide both kinds of ______ (of the samples and of the environment)

Makeup air is also ______-filtered in Class II cabinets

______ cultures that potentially generate aerosols are handled in BSCs

Class II cabinets are commonly used in ______ and research laboratories

BSCs of this class are the ______ used cabinets in clinical and research laboratories

Class II cabinets are the ones that provide ______ for the samples and the environment

Unducted BSCs ______ filtered exhaust back into the laboratory

The ______ air is also HEPA-filtered in Class II cabinets

BSCs of this class handle ______ cultures that potentially generate aerosols

Filtration occurs naturally in the human body, specifically in the kidneys through a process called glomerular filtration.

A Biological Safety Cabinet (BSC) is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with pathogens.
BSCs provide a defined biosafety level, and the Centers for Disease Control and Prevention (CDC) classifies them into three classes.

Classes of BSCs are distinguished by the level of personnel protection, environmental protection, and product protection provided.
Class II cabinets provide both kinds of protection (of the samples and of the environment) since makeup air is also HEPA-filtered.
Class II cabinets are the most commonly used in clinical and research laboratories.

They provide a high level of personnel protection and environmental protection.
They are either ducted (connected to the building exhaust system) or unducted (recirculating filtered exhaust back into the laboratory).
They are used for aerating cultures that potentially generate aerosols.
