How to arrange the ultra-clean bench and other equipment in the laboratory?
The ultra-clean workbench in the pharma machinery sucks the air into the pre-filter through the fan, and enters the high-efficiency filter through the static pressure box for filtration, and sends the filtered air in a vertical or horizontal airflow state, so that the operating area can reach the 100-level cleanliness , to ensure the environmental cleanliness requirements of production or experimental operations; its structure mainly includes electrical parts, blowers, tertiary filters and ultraviolet lamps; turn on the ultraviolet lamps before using the ultra-clean workbench to deal with the purification of the air in the work area and surface accumulation After 30 minutes, turn off the UV lamp and start the blower to remove dust particles. It can be operated in the work area within 10-20 minutes. After the work is completed, the blower is stopped, the countertop is sanitized and cleaned, and the dustproof curtain is put down.
The ultra-clean workbench should be installed in a clean and dust-free room to avoid direct sunlight. It is better if it can be placed in a sterile operation area, which not only has good effect, but also prolongs the service life of the filter; other Supplies not related to cell culture should not be used as storage rooms. Turn on the UV lamp for sterilization half an hour before each use, then turn off the sterilization lamp to start the fan, and then operate. Workbenches that have not been used for a long time should be thoroughly cleaned before use. , disinfection and sterilization, scrub the table with 75% alcohol, the dust of the filter equipment can be removed with a vacuum cleaner, and it is best to cover it with a dust cloth or plastic cloth when it is stopped to avoid dust accumulation; it is not often used in the sterile operation area. For the purification bench, pay attention to the effect of the filter. Zhongjing Global Purification can supply and install ultra-clean workbenches, and can provide laboratory consulting, planning, design, construction, installation, transformation and other supporting services.
The agarose gel electrophoresis detection of PCR products in the laboratory, as well as the electrophoresis of proteins and nucleic acids in molecular microbiology, require the use of electrophoresis instruments. According to the output voltage, electrophoresis instruments can be divided into normal pressure, medium Pressure and high-pressure electrophoresis apparatus, general electrophoresis detection of PCR products can use atmospheric pressure electrophoresis apparatus, and nucleic acid sequence analysis needs to use medium and high pressure electrophoresis apparatus; electrophoresis apparatus provides constant voltage or constant current for the electrophoresis process, and finally achieves Separate different substances; the electrophoresis tank is the core part of the electrophoresis system, which is generally composed of samples, carriers, buffer solutions, positive and negative electrodes, etc.; The switch is placed in the off position, and the voltage-stabilizing and current-stabilizing selection switch is placed in the required working state; the power cord is connected, the power switch is turned on, the output adjustment knob is rotated, and the voltage or current is adjusted to the required value to start electrophoresis; electrophoresis; When finished, turn the voltage knob to the minimum position and turn off the power switch.
