Class II Biological Safety Cabinet

<p>Lab Expo Class II Biological Safety Cabinet are fully enclosed units with safety levels A2 and B2. They provide choices for either 100% air exhaust or 70% air recirculation. These cabinets have HEPA filters for enhanced filtration and glass doors that may be inclined or vertical. They utilize air insulation to prevent cross-pollution and preserve vertical negative pressure. They have energy-efficient designs, stainless steel workspaces, LCD digital screens, and microprocessor controls. Our Class II Biological Safety Cabinet securely manage dangerous items and infections, safeguarding both people and the surrounding area.</p>

FAQ for Class II Biological Safety Cabinet

1: What are the air exhaust and recirculation options in a Class II Biological Safety Cabinet?

Class II Biological Safety Cabinets provide options for either 100% air exhaust used when working with toxic chemicals or radionuclides or approximately 70% air recirculation, where filtered air is returned to the workspace to maintain containment and energy efficiency.

2: What type of filtration is used in Class II Biological Safety Cabinets?

Class II Biological Safety Cabinets are equipped with high-efficiency particulate air (HEPA) filters that remove 99.97% of airborne particles ?0.3 microns, ensuring a sterile work environment and preventing cross-contamination.

3: How do Class II Biological Safety Cabinets prevent cross-contamination between samples?

These cabinets use air insulation barriers and controlled airflow patterns primarily vertical laminar flow and HEPA filtration to isolate samples, ensuring that contaminants do not travel across the work surface and affect other materials.

4: Why is vertical negative pressure important in Class II Biological Safety Cabinet?

Vertical negative pressure ensures that any potentially contaminated air is drawn downward and into internal filters rather than escaping into the laboratory, protecting both the operator and the environment.

5: How do these cabinets protect laboratory personnel and the environment?

They use a combination of HEPA filtration, laminar airflow and negative pressure containment to prevent the escape of harmful aerosols, ensuring that both the user and the surrounding area remain protected.
