Under no circumstances should the inlet hood of the clean bench be facing the open door or window to avoid affecting the service life of the filter. Adjust the height of each foot to ensure a safe and level of operation.
The power supply of the ultra-clean workbench should use * special circuits to avoid the change of air flow rate caused by circuit overload. Check the UV germicidal lamp, lighting fluorescent lamp and blower to provide the power of air flow. Air filter plate and its sealing: adopt the nutrient agar plate method.
Each time the ultra-clean workbench is used, the experimenter should first turn on the UV lamp on the ultra-clean workbench and use it after 20 minutes of UV irradiation.
Turn on the ultra-clean workbench power supply, turn off the UV lamp, and wipe the disinfection work surface with 75% alcohol or 0.5% peracetic acid.
The vaccination room is intended to be simple, and any items that are not directly related to the work of the room can not be placed in order to maintain sterility. The experimenter should follow the aseptic protocol throughout the experiment.
After the experiment, wipe the work surface with disinfectant, turn off the working power, and turn on the UV light for 15 minutes. * First keep the indoors dry and clean. The humid air will both rust the manufacturing materials and affect the normal operation of the electrical circuit. The humid air is also conducive to the growth of bacteria and mold. A clean environment also extends the life of the filter plate. In addition, regular cleaning of equipment is an important part of normal use. Cleaning should include routine cleaning before and after use and regular fumigation. When fumigation, all gaps should be completely sealed. Cleaning should include routine cleaning before and after use and regular fumigation. When fumigation, all gaps should be completely sealed. For example, the type of ultra-clean workbench with movable baffle cover at the operation port can be sealed with plastic film. The filter plates and UV germicidal lamps of the ultra-clean workbench have a calibrated service life and should be replaced on schedule. The sterile room should be periodically dusted and disinfected with 70% alcohol or 0.5% phenol spray, wiped with 2% chlorhexidine and utensils (70% alcohol is also available), and formalin (40% formaldehyde) plus a small amount of permanganic acid. Potassium is periodically sealed and fumigation, combined with UV sterilization lamps (opening for more than 15 minutes each time), etc., so that the sterile room is always kept highly sterilized.
What should be paid attention to when installing, using and maintaining a clean bench?
The length of service life of a clean bench is related to the cleanliness of the air. In the temperate zone, the ultra-clean platform can be used in the general laboratory. However, in the tropical or subtropical region, due to the high level of pollen or dusty areas in the atmosphere, the ultra-clean platform should be placed in a good double-door. Indoor use.
