Ultra-clean workbench is a kind of local air purification equipment, which is specially used in clean room workshop or sterile room and other working environments. The main application industries include industrial laboratories, biological laboratories, medical and health, biopharmaceuticals and other related industries.
1. Disinfect the required instruments, utensils, bacterial bags, test tubes, etc., and put them into the clean workbench.
2. When using the clean workbench, it should be turned on 30 minutes in advance (press the power button), press the setting button to check the setting of relevant parameters and the working status of the equipment, press the UV lamp button to turn on the UV lamp, and treat the microorganisms accumulated on the surface of the operation area. . When leaving the room where the ultra-clean workbench is located, turn on the UV lamps in the buffer room for sterilization. After the sterilization is completed, the instrument should be turned off for 30 minutes to allow the ozone to be converted into oxygen to avoid stimulation to the operator's body. Then press the fluorescent light button to turn on the fluorescent light and start the fan. to operate.
3. Personnel wear disposable masks, caps and medical latex gloves.
4. Properly open the sliding door of the ultra-clean workbench. Perform the required action. During the whole experiment, the experimenter should operate according to the aseptic operation procedures.
5. After the work is completed, wipe and purify the work surface with 75% alcohol, turn off the blower, turn on the UV lamp for sterilization for 15 minutes, and then turn off the power.
6. After use, fill in the use record.
The ultra-clean workbench is a one-way flow type air purification equipment that provides a local dust-free and sterile working environment. It is widely used in scientific research and production departments that require a local clean and sterile working environment, such as medicine and health, biopharmaceuticals, food, medical scientific experiments, optics, electronics, sterile room experiments, sterile microorganism testing, plant tissue culture inoculation, etc. It can also be connected into an assembly line with the advantages of low noise and mobility. It is a kind of air purification equipment that provides local high cleanliness working environment with strong versatility. Its use has good effects on improving process conditions, improving product quality and increasing yield.
A clean bench is different from a biological safety cabinet. The ultra-clean workbench can only protect the reagents operated in the workbench from contamination, and does not protect the staff, while the biological safety cabinet is a negative pressure system, which can effectively protect the staff.
Its working principle is that the air is sucked into the pre-filter by the fan, and filtered by the high-efficiency filter through the static pressure box. cleanliness requirements. The ultra-clean workbench is divided into vertical flow ultra-clean workbench and horizontal flow ultra-clean workbench according to the direction of air flow. According to the operation structure, it can be divided into two forms: unilateral operation and bilateral operation. According to its use, it can be divided into ordinary ultra-clean work. bench and biological (medicine) ultra-clean workbench.
The principle of the ultra-clean workbench is that in a specific space, the indoor air is pre-filtered by a pre-filter, pressed into a static pressure box by a small centrifugal fan, and then filtered by a high-efficiency air filter. The blown clean airflow has a certain and uniform cross-sectional wind speed, which can remove the original air in the working area and take away dust particles and biological particles to form a sterile and high-clean working environment.
