JSCB-1200SB from JS Research – Class II Type A2 microbiological safety cabinet
The JSCB-1200SB from JS Research is biological protection equipment designed to meet the strict containment requirements of laboratories handling biological agents of BSL-1, BSL-2 and BSL-3 levels.
Designed with a vertical laminar airflow system, the JSCB-1200SB draws ambient air through an inlet grille, directs it to a negative pressure plenum, and then distributes it evenly over the work area after HEPA filtration. This process significantly reduces the risk of cross-contamination and maintains a sterile working environment. Approximately 70% of the filtered air is recirculated inside the hood, while 30% is discharged into the room after passing through a second HEPA filter. For even more stringent requirements, a ULPA filter option is available, offering 99.999% filtration efficiency for particles larger than 0.12 µm.
Protection and performance in the laboratory
The JSCB-1200SB biological safety cabinet is constructed with mini-pleated HEPA filters with aluminium frames, offering 99.993 to 99.995% efficiency for particles larger than 0.3 µm. Its design meets the highest safety standards, ensuring that airborne particles are effectively captured. Air is distributed at an optimal speed of 0.3 m/s in downward flow and 0.5 m/s in inward flow, ensuring continuous protection.
The digital control system with integrated microprocessor and graphic LCD display allows precise adjustment of the air speed over 10 levels, as well as independent control of the LED and UV lamps. The adjustable UV sterilisation timer and filter usage counter ensure reliable maintenance monitoring.
Comfort, ergonomics and safety
For user comfort, the JSCB-1200SB is equipped with an ergonomic armrest and a 3° angled front window, reducing fatigue during long work sessions. The removable 304 stainless steel work area facilitates cleaning and decontamination. The front panel opens for quick access during maintenance and can be completely closed to keep the interior clean and prevent exposure to UV radiation during sterilisation mode.
Quiet operation is ensured by a vibration-free motor fan, while LED lighting provides optimal visual comfort with a light intensity of 1510 lux. A 253.7 nm germicidal UV lamp is integrated into the work area for disinfection between uses. The system features automatic safety features such as UV lamp shut-off when the door is opened, overcurrent protection and a filter replacement alarm.
The epoxy powder-coated SPCC sheet steel frame gives the JSCB-1200SB excellent resistance to corrosion and common chemicals. Its tempered glass window ensures operator safety while providing perfect visibility.
With its combination of safety, comfort and performance, the JSCB-1200SB is the ideal choice for any laboratory seeking to ensure a safe working environment that complies with the most stringent regulations.
