What exactly is cleanroom classification? ISO 14644-1 and older standard FS 209E determine class by the concentration levels of particles. The particles range in size from .1 -.5 microns (µm). The class defines a minimum cleanliness level, not a specific design. However class will greatly impact design considerations such as filtration, HVAC requirements and other design elements. Please call AdvanceTEC to discuss your specific requirements.
Biosafety levels define the levels of containment required for handling various types of biological hazards. In the United States, there are four levels of containment as specified by the Centers for Disease Control and Prevention (CDC). The table below is based on information provided by in CDC publications.
