(12) Number of users: 1-2 people
2. Biosafety:
(1) Personnel safety: Tested using potassium iodide (KI) method, the protective factor of the front window operating port should not be less than 1 × 105
(2) Product safety: Colony count ≤ 5CFU/time
(3) Cross contamination safety: colony count ≤ 2CFU/time
2、 Structural and functional characteristics:
1. The cabinet adopts a 10 ° inclined angle design, which conforms to the principles of ergonomics, has a larger perspective, is easy to operate, and is more user-friendly;
2. 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;
3. The work area adopts a negative pressure surrounding design on four sides (left and right sides, rear, bottom), which provides better protection and safety;
4. The workbench is made of high-quality 304 # stainless steel and adopts a bowl shaped design. Even if there is any waste liquid overflow during the experiment, it will not flow into the liquid accumulation tank, making it easy to clean;
5. Fuma Castor Design: The integrated design of the casters and the bracket allows the safety cabinet to move safely through the casters, and can also be fixed and leveled by adjusting the support feet of the casters;
6. The cabinet and bracket can be separated, and the height of the bracket can be customized and modified according to the actual situation;
7. Reasonable structural design: The maintenance and replacement of the filter and fan in the safety cabinet can be carried out on the front side of the safety cabinet, which can be replaced by a single person, making it more efficient; The four cushion blocks at the bottom of the cabinet reserve space for lifting, making handling safer and more convenient.
8. 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;
9. LCD color LCD display screen, full parameter display, real-time dynamic display of the 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 the filter's service life with barcode. When the barcode is fully lit, the filter's service life expires, and the operating status is fully displayed, making it clear at a glance;
10. Flexible control of glass door lifting through three methods: foot operated electric, touch button, and remote control electric. When the glass door reaches a safe operating height, it automatically stops lifting, making operation more convenient; And when lifting the glass door, there is no need to directly contact the glass, making the experimental personnel safer;
11. 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;
12. It has an appointment and timing function, which can automatically set the safety cabinet's scheduled startup, shutdown, and UV lamp disinfection time, greatly saving work time and improving work efficiency;
13. Strict airtightness testing: pressurize the safety cabinet to 500Pa and maintain it for 10 minutes before the air pressure does not fall below 450Pa.
14. Front window airflow partition design: prevents airflow from leaking through the side walls and upper sides of the front window, making the test safer;
15. Excellent fan selection: When the safety cabinet is operating normally without adjusting the speed control of the motor, and the air pressure through the filter decreases by 50%, the exhaust volume of the fan decreases by no more than 10%
16. 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) High filter pressure 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 an audible and visual alarm for filter replacement;
(4) Air flow fluctuation alarm: When the air flow fluctuation of the safety cabinet exceeds 20% of the nominal value, an audible and visual alarm will sound,
17. Safe chain protection design: Chain protection is set for accidental operation, so even if accidental operation occurs, it will not cause harm
(1) Interlocking between safety cabinet fan and glass door: When the glass door of the safety cabinet falls to the bottom, the safety cabinet fan automatically closes, which further protects the use of the safety cabinet and increases its service life
(2) The ultraviolet lamp is interlocked with the glass door, fan, and lighting of the safety cabinet: the ultraviolet lamp can only be turned on when the glass falls to the bottom and the lighting is not turned on, preventing the accidental operation of the ultraviolet lamp from causing harm to human health and further protecting personnel safety;
18. Double trigger signal for front window closure, enabling the UV lamp sterilization and disinfection function to be activated normally;
19. The negative pressure air duct is equipped with a foreign object filtering structure to prevent foreign objects such as paper scraps from entering the fan system and affecting the normal operation of the product;
3、 Qualification certificate and technical documents
