Clean Bench
The laboratory ultra-clean bench is designed to protect the experimental materials. The air is sucked into the pre-filter through the fan, and filtered by the high-efficiency filter through the static pressure box, and the filtered air is sent out in the state of vertical or horizontal airflow , so that the operating area can reach the corresponding level of cleanliness to ensure that the requirements for environmental cleanliness of the experiment are met; the advantages of the ultra-clean workbench are that it is easy to operate, more comfortable, high work efficiency, short preparation time, and can be operated for more than 10 minutes after starting up. Basically, it can be used at any time; compared with the sterile hood, the ultra-clean bench has the advantages of allowing the operator to move freely, easily reaching the operating area and higher safety.
The clean environment of the ultra-clean workbench is formed by the flow of clean air in a set direction in a specific space, which is divided by the direction of the airflow. The existing ultra-clean workbench can be divided into vertical type, from the inside to the outside From the perspective of operating quality and impact on the environment, the vertical type is superior. The clean air provided by the air supply filter plate descends through the operating area at a specific speed, and is separated approximately in the middle of the operating area. It is sucked by the front air suction hole and the rear suction window, mixed with the sucked air in the lower part of the operation area, and pumped into the rear positive pressure area by the blower; in the upper part of the machine, 30% of the air passes through the exhaust filter. The board is exhausted from the top, and about 70% of the gas re-enters the operating area through the oxygen supply filter board; to supplement the air discharged from the exhaust port, the same volume of air is supplemented from the room air through the operating port, and these air will never enter the operation. area, just form an air barrier.
The ultra-clean workbench has been strictly tested before leaving the factory to ensure normal use, but this does not mean that the manufacturer's test can replace the operator's necessary inspection and debugging before use, because the environment where the ultra-clean workbench is located Different, only after proper inspection and debugging can the function of the equipment be maximized; before debugging, a better environment should be selected for the machine, placed in a sterile room with air disinfection facilities, and adjusted. The height of the feet to ensure the stability and the level of the operation surface; the power supply of the ultra-clean workbench should adopt a special circuit to avoid the change of the air flow rate caused by the overload of the circuit; the ultraviolet germicidal lamp and the fluorescent lamp for lighting are the standard configuration of the ultra-clean workbench , the blower provides the power for air flow. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for laboratories and GMP workshops.
The ultra-clean workbench should be irradiated with ultraviolet light before use, and check that the various openable doors and windows around the operation area are in the working position. No advanced equipment can guarantee the success of the test. The use of the ultra-clean workbench in the animal quarantine laboratory is for the purpose of sterility and avoiding cross-contamination, so skilled operation and clear aseptic essentials are essential. The ultra-clean workbench is a relatively precise electrical equipment, and it is very important to carry out regular maintenance and maintenance. First of all, it is necessary to keep the room dry and clean. The humid air will not only corrode the manufacturing materials, but also affect the electrical circuit. Normal operation, humid air is also conducive to the growth of bacteria and mold, and a clean environment can also prolong the service life of the filter plate; the cleaning of the equipment should include routine cleaning before and after use and regular fumigation treatment, and all gaps should be completely fumigated. Seal, such as the type of ultra-clean workbench with a movable baffle cover at the operation port, it can be sealed with plastic film; the high-efficiency filter and ultraviolet germicidal lamp of the ultra-clean workbench have a useful life and should be replaced on schedule.
The , essentially perfected by extraction machine, is one of the first home appliance to be widely distributed.
