All surfaces within the work area are made of 304 series stainless steel
The front window glass is made of explosion-proof tempered and strengthened glass, which ensures clear optical perspective and is not adversely affected during cleaning and disinfection. The thickness is >6mm. The filter uses ULPA filters, with a filtration efficiency of over 99.9995% for 0.12um particles, meeting the requirements for temperature, humidity, corrosion resistance, and mechanical strength under normal use conditions. The filter material is ultra-fine glass fiber, and the substances that may be released do not have adverse effects on personnel, the environment, or equipment
The exposed working area of the safety cabinet adopts an R8 three-sided seamless rounded corner structure, which enhances the self-cleaning function; the filters and fans can be replaced and maintained at the front of the safety cabinet
The front glass doors and windows adopt a 10-degree physiological bevel angle, providing a wider viewing angle and enhancing user-friendliness
The front window adopts electric lifting, which can be controlled by buttons, remote control, or foot pedal. With three control methods, it avoids direct contact between the user and the glass doors and windows, reducing cross-contamination
Equipped with a high-precision limiter, it features audible and visual alarms when the safe height is exceeded
The front windshield glass is made of UV-resistant, double-layer laminated explosion-proof safety glass
It possesses adequate rigidity, boasts a straightforward design, lacks exposed threads, facilitates cleaning, and can adjust the levelness and stability of the safety cabinet
Equipped with a thermal protection device, it can operate stably at 1.15 times the rated voltage value
It can adjust speed and maintain stable control. The speed controller is installed on the back of a removable or lockable control panel
When the fan motor is operating normally in the safety cabinet without adjusting the motor speed control, and the air pressure through the filter decreases by 50%, the exhaust volume of the fan should not decrease by more than 10%
The liquid collection tank has a capacity of ≥4000ml, designed to collect splattered liquids in the work area. It ensures no significant leakage or infiltration within 1 hour. Additionally, a drain valve is installed underneath the tank for easy cleaning
Pressurize the safety cabinet to 500Pa, and maintain the pressure at not less than 450Pa for 30 minutes
For scannable filters, the leakage rate of the filtered material at any point must be ≤0.001%. For non-scannable filters, the leakage rate at the detection point must be ≤0.005%
The noise level of the safety cabinet is ≤67dB(A)
The average illuminance of the safety cabinet is ≥650 Lux
The net amplitude of vibration between frequencies of 10Hz and 10kHz does not exceed 5um (rms)
The average wind speed of the descending airflow in the safety cabinet is 0.33±0.025m/s
The average wind speed of the inflow airflow in the safety cabinet is 0.53±0.025m/s
High-brightness and clear LCD display, which dynamically shows the temperature, humidity, descending airflow velocity, incoming airflow velocity, filter differential pressure system working time, filter working time, system status safety prompts, and the working status of each system component in the operation area in real time
Remote control reduces direct contact between the user and the safety cabinet, providing better protection for the user. With a preset timing function, it can automatically disinfect, switch on and off, improving work efficiency
After a 23kg pressure is applied to the center of the work surface of the safety cabinet, the work surface does not deform
The socket can support the normal operation of instruments with a power consumption of up to 500W
Personnel safety: When tested using the potassium iodide (KI) method, the protection factor of the front window operation port should be no less than 1x105
Product safety: Colony count ≤ 5 CFU per instance
Cross-contamination safety: bacterial count ≤2 CFU per instance
