2、 Structural and functional characteristics:

1. Jinan Xinbeixi Biotechnology Co., Ltd. is one of the drafting units for the product standard YY0569-2011 Level II Biosafety Cabinet in the pharmaceutical industry of the People's Republic of China; Its safety cabinet complies with both the industry standard YY0569-2011 Grade II Biosafety Cabinet and the national standard GB 41918-2022 Biosafety Cabinet requirements;

2. The cabinet adopts a 10 ° tilt angle design, which conforms to ergonomic principles, has a larger viewing angle, is easy to operate, and is more user-friendly;    

3. The three side wall panels of the exposed work area of the safety cabinet are made of high-quality 304 # stainless steel integrated structure, and the internal washable parts are treated with 8mm large rounded corners, leaving no dead corners and easy to clean;

4. The workspace is designed with negative pressure surrounding it on all four sides (left and right, rear, and bottom) for better protection and safety;

5. The workbench is made of high-quality 304 # stainless steel and adopts a bowl shaped design. Even if there is waste liquid overflowing from the experiment, it will not flow into the liquid accumulation tank, making it easy to clean;

*6. Fuma caster design: The caster and bracket are integrated, and the safety cabinet can be safely moved by the caster, or fixed and leveled by adjusting the caster support feet;

7. The cabinet and bracket can be separated, and the height of the bracket can be customized and modified according to the actual situation;

8. Reasonable structural design: The maintenance and replacement of the safety cabinet filter and fan can be carried out on the front side of the safety cabinet, and can be replaced by a single person, which is more efficient; The four cushion blocks at the bottom of the cabinet reserve space for lifting, making transportation safer and more convenient;

*9. The front window glass adopts double-layer laminated explosion-proof safety glass; Even if the glass is damaged, it will not harm people, and the biosafety cabinet can still work normally until the end of the experiment, better protecting the safety of personnel and the experiment;

*10. LCD color LCD display screen, full parameter display, real-time dynamic display of descending airflow velocity and inflow airflow velocity in the operation area, display of the overall operating time of the safety cabinet, the operating time of the UV lamp, the temperature and humidity in the operation area, the resistance of the supply and exhaust filters, display of the filter's usage time, and display of the filter's service life with a barcode. When the barcode is fully lit, the filter's service life expires, and the operating status is fully displayed at a glance;

*11. The glass door can be flexibly controlled by three methods: foot pedal electric, touch button, and remote control electric. When the glass door reaches a safe operating height, it automatically stops lifting, making the operation more convenient; And the glass door does not need to directly touch the glass when lifting, making the experimenters safer;

12. Remote control: All button operations of the safety cabinet can be achieved through remote control, making the use of the safety cabinet faster and more convenient; The use of remote control greatly reduces direct contact between users and the safety cabinet, further protecting the personal safety of users;

13. Equipped with a scheduled timer function, it can automatically set the timing for the safe cabinet to turn on, off, and disinfect the UV lamp, greatly saving work time and improving work efficiency;

14. Strict airtightness testing: The pressure inside the safety cabinet is increased by 500Pa, and after holding for 10 minutes, the air pressure is not less than 450Pa;

15. Front window airflow partition design: prevents airflow from leaking through the front window sidewall and upper side, making the test safer;

16. Excellent fan selection: When the safety cabinet is running normally without adjusting the speed control of the motor, and the air pressure through the filter drops by 50%, the exhaust volume of the fan will not decrease by more than 10%;

17. A comprehensive alarm system:

(1) Glass door not at safe height alarm: The safe height of the glass door is 200mm. When the front side of the safety cabinet is higher or lower than the safe height, the safety cabinet will sound and light an alarm;

(2) Filter pressure over high alarm: When the resistance of the filter increases, the safety cabinet will sound and light an alarm;

(3) Filter failure replacement alarm: When the service life of the filter expires, there will be a filter replacement sound and light alarm;

(4) Airflow fluctuation alarm: When the airflow fluctuation of the safety cabinet exceeds 20% of the nominal value, an audible and visual alarm will be triggered;

18. Safe chain protection design: Chain protection is set up for misoperation, so even if misoperation occurs, it will not cause harm

(1) Interlocking between safety cabinet fan and glass door: When the safety cabinet glass door falls to the bottom, the safety cabinet fan automatically shuts off, which further protects the use of the safety cabinet and increases its service life;

(2) UV lights are interlocked with safety cabinet glass doors, fans, and lighting fixtures: the UV lights can only be turned on when the glass falls to the bottom and the lighting fixtures are not turned on, preventing accidental operation of the UV lights from causing harm to human health and further protecting personnel safety;

*19. Double trigger signal for closing the front window, enabling the UV lamp sterilization and disinfection function to be activated normally;

*20. The negative pressure air duct is equipped with a foreign object filtering structure to prevent paper scraps and other foreign objects from entering the fan system and affecting the normal operation of the product.
