The vertical flow workbench is an air purification device that provides a local high-cleanliness environment. Its airflow moves vertically, isolating external pollution and preventing the spread of pollutants during operation. It is widely used in fields with high cleanliness requirements, such as:
I. Biomedical Field
In microbiological research, it is used for experiments such as isolating, culturing, and identifying microorganisms like bacteria, fungi, and viruses. For example, when studying new pathogenic bacteria, researchers operate within a vertical flow workbench. This setup prevents external contaminants from affecting samples and reduces health threats to operators by containing pathogens.
Cell culture: The culture of animal cells, plant cells and stem cells has strict requirements for environmental cleanliness. The vertical flow workbench can create a sterile and dust-free environment, ensuring that cells are not contaminated during the culture process and maintaining their normal growth state and biological characteristics. It is an indispensable device in cell laboratories.
Medical device handling: For some precision medical devices (such as minimally invasive surgical instruments and ophthalmic surgical instruments), the assembly and debugging before use, as well as the cleaning, disinfection and examination after operation, need to be carried out in a clean environment. The vertical flow workbench can prevent the devices from being contaminated and ensure medical safety.
Ii. Pharmaceutical Industry
In the production process of pharmaceuticals such as tablets, capsules and injections, key steps such as weighing, mixing and packaging of raw materials are involved. These steps have strict limits on the content of particles and microorganisms in the environment. Vertical flow workbenches can provide a clean space for these operations, prevent drugs from being contaminated, and ensure that the quality of drugs meets national standards.
Drug development experiments: During the process of new drug development, researchers need to conduct experiments such as drug synthesis, efficacy tests, and drug stability tests. Among them, the purity control of drug synthesis reactions and the processing of samples in efficacy tests all need to be carried out in a clean environment. The vertical flow workbench can meet the cleanliness requirements of these experiments and improve the accuracy and reliability of the experimental results.
Iii. Electronic Manufacturing Industry
Semiconductor chip production: The manufacturing process of semiconductor chips is extremely precise. The circuit width on the chip is measured in nanometers, and even the tiniest dust particles can cause the chip to fail. Vertical flow workbenches are widely used in the photolithography, etching, packaging and other processes of chips, providing a high-cleanliness environment for these operations, effectively removing particles in the air and ensuring the yield of chip production.
Precision electronic component assembly: Precision electronic components such as micro-sensors and integrated circuit boards in smart phones and tablet computers have high requirements for environmental cleanliness during the assembly process. If dust adheres to the surface of the components, it may affect the electrical performance and service life of the components. The vertical flow workbench can ensure that the assembly process takes place in a clean environment, improving the assembly quality of electronic components.
Iv. Food Processing and Inspection Field
Sterile food production: In the production process of sterile foods such as fruit juice, dairy products, and canned foods, operations such as sterilization and filling of food raw materials are required. To prevent food from being contaminated by external microorganisms from sterilization to filling, key steps such as filling must be completed in a vertical flow workbench to ensure the safety and quality of food within its shelf life.
Food microbiological testing: When food quality inspection institutions test the microorganisms in food (such as Escherichia coli and Salmonella), they need to process, cultivate and observe the food samples. The vertical flow workbench can provide a sterile environment for these testing operations, preventing external contaminants from interfering with the test results, ensuring the accuracy of the test data, and providing a reliable basis for food quality supervision.
