A. Precautions: the length of service life of the ultra-clean bench and the cleanliness of the air. In temperate regions ultra-clean bench can be used in the general laboratory, however, in tropical or subtropical regions, by the amount of pollen in the atmosphere, or dusty areas, the ultra-clean bench should be placed in a better double door indoor use.
In no case should not be ultra-clean table air intake hood to the open door or window, so as not to affect the service life of the filter. In the ultra-clean bench can also be suspended in the ultraviolet lamp, but should be installed in the lighting outside the hood, and staggered lighting arrangement, so that the work does not interfere with the lighting.
Do not put the ultraviolet lamp into the lighting lampshade (glass plate) inside, because the ultraviolet light can not penetrate the glass, its lamp is quartz glass, rather than silicate glass.
Two, the use of ultra-clean workbench procedures:
1, when using the workbench, the first after the cleaning solution soaked gauze to wipe the surface of the table, and then disinfectant wipe disinfection;
2, turn on the power supply, open the UV lamp irradiation disinfection in advance of 50 minutes to deal with the purification of microorganisms accumulated in the surface of the table within the work area, 30 minutes later, turn off the UV lamp, turn on the blower!
3, workbench surface, do not store unnecessary items to keep the clean airflow in the work area without interference;
4, the end of the operation, clean up the workbench surface, collect all the waste, turn off the fan and the lighting switch, with detergent and disinfectant wipe disinfectant;
5, and finally turn on the workbench ultraviolet lamp irradiation disinfection for 30 minutes after the turn-off of UV lamps, cut off power;
5, the last turn on the workbench ultraviolet lamp irradiation sterilization Light, cut off the power supply;
6, every two months with an anemometer to measure the average wind speed in the work area, such as found to be inconsistent with the technical standards, should be adjusted regulator handle, change the fan input voltage, so that the workbench is in the best condition;
7, once a month to carry out maintenance inspections and fill in the maintenance records.
Expanded information:
A, ultra-clean bench (clean bench), also known as the purification workbench, is in order to adapt to the modernization of the industrial, photovoltaic industry, biopharmaceuticals, as well as scientific research and experimentation and other fields of the cleanliness of the local work area demand And the design.
The air is sucked into the pre-filter through the fan, and then filtered into the high-efficiency filter through the static pressure box, and then the filtered air is sent out in the state of vertical or horizontal airflow, so that the operation area reaches the cleanliness of class 100 to ensure the production of the environmental cleanliness requirements.
Two, the principle of ultra-clean bench:
It is in a specific space, the indoor air through the pre-filter primary filtration, pressed by a small centrifugal fan into the static pressure box, and then through the air high-efficiency filters secondary filtration, from the air high-efficiency filters out of the air out of the surface of the clean air flow with a certain and uniform cross-section of the air velocity, can be excluded from the original air in the work area, dust particles and biological particles to take away, in order to form a sterile high cleanliness. The airflow from the air outlet of the AHF filter has a certain and uniform cross-section wind speed, which can exclude the original air in the working area and take away the dust particles and biological particles to form a sterile and highly clean working environment.
Three, ultra-clean bench use:
It is a one-way flow air purification equipment to provide a local dust-free and sterile working environment. Applicable to medicine and health, biopharmaceutical, food, medical science experiments, optics, electronics, aseptic chamber experiments, sterile microbiological testing, plant inoculation and other needs of the local clean and sterile working environment of the scientific research and production departments.
Can also be connected to the assembly line with low noise, mobility and other characteristics. Its use to improve process conditions, improve product quality and increase the yield are good results.
