2. Biological security:
(1) personnel safety: the protection factor of the front window operating port shall not be less than 1 x 105 tested by potassium iodide (KI) method
(2) product safety: the number of colonies is no more than 5CFU/ time
(3) safety of cross contamination: the number of colonies is less than or equal to 2CFU/ time Structural features:
1, the cabinet put oneself in another's position with 10 ° Angle design, accord with human body engineering principle, the Angle is bigger, easy to operate and more human;
2. The three side walls of the working area exposed by the safety cabinet are made of high quality 304# stainless steel, and the cleaning part inside is treated with 8mm large rounded corner, without any dead corner, which is easy to clean.
3. The working area adopts four sides (left and right sides, rear and bottom) negative pressure to surround the design work area, which is more protective and safe.
4. The work table is made of high-quality 304# stainless steel and adopts the basin type design. Even if there is a waste liquid overflow in the experiment, it will not flow into the accumulator for cleaning.
5. Fuma foot wheel design: the castor and bracket are integrated design. The safety cabinet can be moved safely by the castor, and can be fixed and adjusted by adjusting the foot of the castor.
6. The cabinet and bracket can be separated, and the bracket height can be customized and modified according to the actual situation;
7. Reasonable structural design: maintenance and replacement of safety cabinet filters and fans can be carried out on the front side of safety cabinet, which is more convenient and fast.
8. The front window glass adopts double-layer laminated safety glass;
Even if the glass is broken, it will not hurt people, and the biosafety cabinet can work normally until the end of the experiment, which better protects the personnel and the safety of the experiment.
9, high brightness LCD display screen, the operation of the real-time dynamic display of downwash velocity and into the airflow velocity, show whole running time of the safety cabinet, the running time of UV lamp, the temperature and humidity of operation area, the resistance of the air supply and exhaust air filters, and indicates that the use of filter time by bar code shows that the service life of filter, bar code is all light filter life expires, running state, according to all be clear at a glance.
10. Electric control of the front window and glass door can be operated by foot control, button control or remote control at the same time. When the glass door is lifted to a safe height, it will automatically stop lifting, making the operation more convenient.
And the glass door is not directly touched when lifting, which makes the experimenter safer.
11. Remote control: all key operations of the safety cabinet can be realized through remote control, so that the safety cabinet can be used more quickly and conveniently.
The use of the remote control greatly reduces the direct contact between the user and the safety cabinet, and further protects the user's personal safety.
12. It has the function of appointment timing. It can automatically set the time of starting up, shutting down and sterilizing the ultraviolet lamp of the safety cabinet.
13. Strict air tightness test: pressurize 500Pa in the safety cabinet and keep the pressure at no less than 450Pa after 30min.
14. Air separation design of the front window: it prevents air leakage through the side wall and upper side of the front window, making the test safer;
15. Good choice of fan: when the safety cabinet is running normally without adjusting the speed control of the motor, when the air pressure of the filter drops by 50%, the displacement of the fan does not exceed 10%
16. Perfect alarm system:
(1) the glass door is not at the 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 give an audible and visual alarm;
(2) ultra-high filter pressure alarm: when the resistance of the filter increases, the safe cabinet will sound and light alarm
(3) filter failure and replacement alarm: when the filter life expires, there will be a sound and light alarm;
(4) air flow fluctuation alarm: when the air flow fluctuation of the safety cabinet exceeds 20% of the nominal value, the sound-light alarm is given.
17. Safe linkage protection design: the linkage protection is set for the wrong operation. Even if the wrong operation, no harm will be caused
(1) interlock the safety cabinet fan and the glass door: when the glass door of the safety cabinet falls to the bottom, the safety cabinet fan is automatically closed, which protects the use of the safety cabinet and increases the service life of the safety cabinet
(2) interlock the ultraviolet lamp with the glass door of safety cabinet, fan and floodlight: when the glass falls to the bottom and the lamp does not open, the ultraviolet lamp can be opened, which prevents the ultraviolet lamp from wrong operation causing harm to human body and further protects the safety of personnel;
