Working principle of ordinary microbial limit tester
Inject the test substanceMicrobial limit incubatorInternally, the testing instrument is equipped with an imported diaphragm liquid pump for negative pressure filtration, which traps microorganisms in the test sample on the filter membrane. The filter membrane is then removed using a membrane extractor and transferred to a prepared solid culture medium, with the bacterial surface facing upwards and flat. Cover the lid to form a closed culture box, place it in the corresponding constant temperature culture box for cultivation and counting.GY-ZXDY Purified Water Microbial Limit Tester Manufacturer

Make good records and provide detailed archival information for the normal operation and daily maintenance of the instrument in the future. Construction of maintenance team
To ensure the normal operation of experimental instruments and equipment, it is not only necessary to have sufficient maintenance funds, but also to ensure the timeliness of equipment maintenance. Relying on manufacturers for maintenance is costly and time-consuming. Therefore, our unit should gradually cultivate its own maintenance team to regularly maintain the equipment. The equipment management department should formulate an annual instrument and equipment maintenance plan based on the actual situation. This not only saves funds but also ensures the real-time maintenance. Therefore, establishing a lean and efficient maintenance team based on our unit is a necessary condition to ensure the normal operation of instruments. Regularly provide technical training to technical and management personnel to improve maintenance skills and management level, and continuously accumulate maintenance experience through practice. Pay attention to the procurement of consumables and maintenance spare parts. Imported instruments are often paired with imported original consumables. In consideration of ensuring the accuracy of test data is not affected, domestic consumables and spare parts can be tried to reduce testing costs. There are currently domestically produced substitute consumables with stable performance, such as the element lamp used in atomic absorption and the injection tube used in thermal desorption instruments for analytical instrument injection, which are much cheaper than imported consumables. For frequently used maintenance spare parts, there should be spare parts to reduce the time cost of purchasing them when problems occur. The management and maintenance of laboratory instruments and equipment can not only improve the standardization of laboratory instrument and equipment management, but also further enhance the effective utilization rate of laboratory equipment; It can also strengthen the safety management of laboratory instruments and equipment, which plays an important role in the smooth completion of experiments. Establishing strict rules and regulations for the management and maintenance of laboratory equipment and instruments is of great significance in ensuring the quality of experiments. Comprehensively improving the comprehensive quality of management personnel, strengthening the sense of responsibility of operators, and improving instrument maintenance records not only solve the problems of high maintenance requirements, heavy tasks, and tight time, but also save costs for testing and improve the efficiency of the use of testing instruments, providing strong support for the construction of a scientific, fair, accurate, and efficient testing service platform.
The former is sterilized for 2 hours, while the latter is sterilized for 30 minutes. The calibration time for the drying sterilization oven is generally one year.
For the control of distilled water used in the preparation of culture media, it is necessary to regularly clean the ion exchanger and replace the ion exchange material according to the equipment instructions. Testing requirements: The Western European standard specifies that the specific conductivity of distilled water used for microbiological testing should be less than 0.5mS/m; Bacterial count<50cfu/ml. Our daily standard is<10ms/m, and no bacterial indicators have been found. Testing frequency: once a month
Maintenance of pH meter: Regular cleaning of electrode surface; Electrode sensitivity detection and polarity recovery. The control level flow of the purification workbench requires a cleanliness level of 100 in the working area of the purification workbench. The air settles for 30 minutes and the bacterial count is less than 1 per dish. Currently, the maintenance of instruments and equipment is a rather complex task, and many institutions have equipment departments responsible for maintaining the safety and stability of equipment. However, there are still many issues that many equipment maintenance personnel do not understand or pay enough attention to. Here, we would like to once again introduce the maintenance and upkeep of medical equipment to everyone. Careful daily maintenance and upkeep are crucial for ensuring the normal operation of instruments and equipment
Daily maintenance may seem simple, but it is often not taken seriously and can be easily overlooked; But often, big problems are accumulated from small problems. To actively cooperate with clinical users and maintain the cleanliness of the instrument surface; Before use, check whether the voltage and power supply are normal; During use, pay attention to observing whether the instrument is functioning properly and fill in the usage record. Develop good habits during daily maintenance to avoid damage incidents. The second point is that equipment maintenance work must be handled carefully and not be careless
When equipment malfunctions, it is necessary to collect and prepare information before maintenance; Including model, factory number, time of fault occurrence, whether there is any abnormal sound when the fault occurs, whether there has been a sudden power outage, whether the instrument has been moved, and other issues. During maintenance, attention should be paid to the order of disassembly of medical equipment, and brute force should be avoided. The removed fastening screws, small parts, etc. should not be placed randomly. They should be sorted and stored properly to avoid loss. After the equipment maintenance is completed, during installation, it should be restored to its original state step by step in reverse order, without any unnecessary accessories. Damaged spare parts should also be marked and replaced to restore their original condition without any errors. After the maintenance work is completed, clean the surface of the instrument, turn on the power, and see if it can work properly. Calibrate the instrument, restore normal working condition, and then hand it over to
