Biological Safety Cabinet, Class II Type B2, BSC-2B2 Series

  1. Type: Class II, Type B2
  2. Venting Mode: 100% Outward venting
  3. Available Width: 4ft.
  4. Cleanliness Class: ISO4 (Class 10)
  5. ULPA Filter technology used,over 99.9995% filtering ratio of 0.1-0.2um dust particle


  1. Front window: anti-cracking toughened glass, clear optics perspective, no side effect while cleaning or sterilizing, thickness of glass ≥ 5mm;
  2. Cabinet body: four-faced and double layer structure, stainless steel 304(imported)used for all operating chambers and catchment grooves; incorporated structure of the three sidewalls in operating area, leaving some space on the bottom for cleaning purpose, avoiding cross infection Maintenance of blower/motor and/or disassembly/ assembly/replacement of high efficiency filter could be done at the front part of safety cabinet.
  3. Leakage-proof of cabinet body: apply air pressure 500pa to safety cabinet and the pressure shall not be less than 450Pa after 30 minutes.
  4. Stability of cabinet body: apply 23kg load on center of work table, no bend shall occur.
  5. Alarm system: the interlocking system will be started up, generating alarm in sound, light and voice form at the same time if the open height of front window of safety cabinet exceeds the setting value/flow speed fluctuation of downflow and/or inflow is 20% more than nominal value.
  6. The perfection of high efficiency filter:
    missing rate ≤ 0.01% at any point for scannable detection filter missing rate ≤ 0.005%at detecting point for unscannable detection filter
  7. Personal protection: colony amount ≤ 10CFU per time for impact type sampler; colony amount ≤ 5CFU per time for slit type sampler
  8. Product protection: colony amount ≤ 5CFUper time; colony amount ≤ 2CFU per time
    The 12 new functions of the new type safety cabinet
  9. Pioneered at home, high accuracy wind speed sensor of ultra micro differential pressure sensor and frequency conversion controlling technology adopted to automatically regulate speed of airflow, extending service life of filter scientifically
  10. ULPA Filter technology used, over 99.995% filtering ratio of 0.3um dust particle
  11. High-class blower system: Three-phase AC asynchronous motor adopted, more stable operation, lower noise, less electric consumption, less maintenance cost
  12. Record of accumulated operating time for in time understanding filter service life and blower maintenance period
  13. Perfect alarm/protection system, generating voice, light and electric alarm at the same time
  14. Keyboard lockout to prevent you from unwanted lost due to Mis-operation
  15. Friendly man-machine interface: all parameters displayed at the same time
  16. Four-faced and double layer structure to ensure negative pressure on each of the four faces in operating area
  17. Simple and convenient maintainability: stainless steel304# used for inner body and catchment disc, once-shaping innerbody,R15 arc processing
  18. Unique technology :when sitting, you can perform all these activities- watching pressure gauge, adjusting the height of exit door and controlling power supply in the cabinet
  19. Interlocking UV light, protecting tester and test sample
  20. Electric front window of automatically locating type, using foot or hand operated switch to locate at your will, easy to operate

Basic characteristics:

  1. Use a color LCD with high brightness and resolution providing an animated simulation to indicate the state of safety cabinet.
  2. Provide the function of scheduled and time-limit sterilization.
  3. Keep the record of accumulated operating time of illuminating lamp, sterilizing lamp or air blower.
  4. Add a prompt(clearable)of replacing illuminating lamp when its accumulated operating time exceeds 5000 hours.
  5. Add a prompt (clearable) of replacing sterilizing lamp when its accumulated operating time exceeds500 hours.
  6. Add the indication of filter life.
  7. Add the function to remotely control the rising and falling of blower, illuminating lamp, sterilizing lamp and front window.
  8. Add the clock setting and real-time display function
