1.Microbiological Research

In the field of microbiological research, the automatic solid medium preparation and dispensing system is a core auxiliary tool in experiments, which can greatly improve experimental efficiency and accuracy. In microbial isolation experiments, researchers need to inoculate different samples into suitable media. The system can quickly prepare various types of plate media. Whether it is ordinary nutrient agar or selective or differential media for specific microorganisms, it can be accurately dispensed according to the preset thickness and uniformity.

The prepared plates have strong consistency, avoiding the problems of uneven thickness and uneven nutrient distribution caused by manual preparation, laying a good foundation for subsequent microbial isolation. During strain screening and purification, the system supports two commonly used inoculation methods: pour plate method and spread plate method. When using the pour plate method, the system can smoothly and evenly pour the melted and cooled liquid medium into the petri dish.

Combined with the automatic oscillation mixing function, it can fully mix the sample with the medium to prevent bacterial accumulation or uneven distribution, ensuring the independent growth of single colonies and facilitating subsequent observation of morphology and identification. When operating the spread plate method, the system first accurately controls the coating amount of the medium, and cooperates with the uniform movement of the coating tool to make the medium form a thin and even coating on the bottom of the dish, which is suitable for the cultivation of microorganisms with high oxygen demand and sensitivity to coating. In addition, the system can flexibly set the dispensing volume from 12 to 30 mL, and the rapid mixing function can accelerate subsequent steps, meeting the needs of a series of experiments such as colony count and drug susceptibility tests, significantly shortening the experimental cycle and improving the accuracy and repeatability of experimental results.

2.Pharmaceutical and Sterility Testing

The pharmaceutical and sterility testing field has strict requirements on environmental sterility and operational standardization. The automatic solid medium preparation and dispensing system is a key equipment to ensure the quality of drugs and the accuracy of sterility testing. During the pharmaceutical production process, whether it is the sterility testing of raw materials or the microbial limit test of finished preparations, high-quality sterile media are required. At this time, dispensing equipment with whole-machine sterilization function should be selected. Such equipment can be thoroughly sterilized through high temperature and high pressure or chemical sterilants to eliminate the risk of microbial contamination inside the equipment.

At the same time, disposable sterile pipelines are used to avoid cross-contamination caused by repeated use of pipelines, ensuring that the media are in a sterile state during the whole process of preparation and dispensing.

The system can also accurately control the dispensing volume and uniformity of media in each batch, ensuring the consistency of test results, providing reliable data support for drug production and quality control, and thereby ensuring the safety and effectiveness of drugs.

3.Food and Water Quality Testing

Food and water quality testing laboratories undertake the daily large-scale microbial testing tasks of samples and have high requirements for the efficiency and stability of medium preparation. The automatic solid medium preparation and dispensing system exactly meets this demand and can achieve batch and rapid preparation of plate media. In food testing, for the detection of indicators such as total colony count, coliforms and pathogenic bacteria in raw materials, finished products or production environment samples, the system can continuously prepare plate media of different specifications.

The preparation process has a high degree of automation, reducing errors caused by manual intervention, and is suitable for the laboratory's daily need to process a large number of samples. In terms of water quality testing, whether it is the detection of drinking water, surface water or industrial wastewater, it is necessary to prepare media with specific nutrients and pH values according to standards.

The system can accurately prepare corresponding media according to different testing standards and achieve uniform dispensing to ensure the accuracy of subsequent microbial testing. At the same time, it reduces the labor intensity of manual preparation, allowing laboratories to efficiently cope with daily batch testing work.

4.University Teaching and Scientific Research

In the teaching of microbiology, biology and other related majors in universities, experimental courses need to balance the simplicity of operation and cost controllability. For this demand, the semi-automatic desktop automatic solid medium preparation and dispensing machine is an ideal choice. Such equipment has a simple structure and a low operation threshold, making it suitable for students to practice hands-on in class.

During the teaching process, as long as students manually place the petri dishes in the designated position, they can operate the equipment to complete the addition of media. The simple insulation function can maintain the media in a suitable temperature range to ensure that the media remain liquid and do not solidify, allowing students to intuitively master the preparation process of solid media and deepen their understanding of the principles of microbial cultivation. In the scientific research work of universities, if the research field has moderate requirements for equipment accuracy, such semi-automatic dispensing machines can save scientific research funds by virtue of their economic and practical characteristics.

At the same time, their flexible operation mode can also adapt to the conventional medium preparation needs of different scientific research scenarios, helping to smoothly carry out scientific research work.
