Introduction Class II A2 Biosafety Cabinet

The Biobase BSC-4FA2-NA Class II A2 Biosafety Cabinet creates a protected workspace for the operator, the sample and the laboratory. This NSF certified 4-foot workstation pulls room air through the front grille and filters it with two HEPA filters. Moreover, the airflow system recirculates 70% of the air and exhausts the other 30%. The front window stops at a 254 mm (10-inch) safe working height. A 7-inch color touch display shows airflow, filter life and alarms in real time. Biobase Scientific manufactures the cabinet in China for microbiology, cell culture and clinical testing. Stainless steel 304 lines the work area, so technicians clean it quickly.

Key Features Biobase BSC-4FA2-NA

1. The three-layer airflow barrier shields the operator, the sample and the lab environment.
2. Two HEPA filters clean both the supply air and the exhaust air.
3. In addition, the motorized front window glides to the safe height with a single touch.
4. The 7-inch color touch display presents real-time airflow and runtime data.
5. The EC fan adjusts airflow automatically, so velocity stays stable as the filters load.
6. Audible and visual alarms flag abnormal airflow, high filter pressure and unsafe window height.
7. Technicians remove the integrated work area easily, which simplifies deep cleaning.
8. Furthermore, a power-on password blocks unauthorized use.
9. The memory function restores the previous state after a power failure.
10. The adjustable base lets the lab match the cabinet height to its operators, so users work comfortably for long hours.

Who Uses This 4 feet safety workstation

1. Clinical laboratories handle blood, urine and swab samples inside the cabinet.
2. Medical colleges and universities train students in sterile technique with it.
3. Diagnostic centers prepare PCR and culture samples in the clean workspace.
4. Biotech and pharmaceutical firms run cell culture and quality tests.
5. Moreover, government research institutes use it for microbiology and molecular biology studies.
6. Similarly, food and water testing labs rely on it for contamination checks.

Applications NSF certified biosafety cabinet

1. Technicians grow cell lines and tissue cultures under sterile downflow air.
2. Microbiologists inoculate, streak and subculture bacterial samples.
3. Moreover, molecular biology teams set up PCR reactions without cross-contamination.
4. Clinical staff process specimens that carry moderate-risk agents.
5. Researchers prepare vaccine and biologic samples during development.
6. Finally, trainers demonstrate aseptic technique in teaching laboratories.
7. However, the cabinet does not suit volatile toxic chemicals or radionuclides, so labs use a Class II B2 cabinet for those tasks.

Frequently Asked Questions / FAQ Class II A2 Biosafety Cabinet

Q1. What does a Class II A2 biosafety cabinet do?
It protects the operator, the sample and the environment during work with moderate-risk biological agents. Moreover, it recirculates 70% of the filtered air and exhausts 30%.

Q2. What are the dimensions of the Biobase BSC-4FA2-NA?
It measures 1383 × 775 × 2295 mm outside and offers a 1210 × 600 × 660 mm work area.

Q3. Which sash height does this cabinet use?
It uses a 254 mm (10-inch) safe working height.

Q4. What power supply does it need?
