1. Introduction to GMP Good Manufacturing Practice (GMP) is a management system that ensures that the entire process of drug production is strictly controlled. Its purpose is to ensure the safety, effectiveness and consistency of drugs. GMP covers multiple aspects such as personnel, equipment, materials, procedures and records, requiring pharmaceutical companies to achieve high standards of cleanliness and pollution control in all links. 2. Definition and type of laminar flow hood Laminar flow hood is an air purification device used to provide a local dust-free and sterile environment. It is widely used in pharmaceutical, medical and research fields that require high cleanliness. According to different application requirements, laminar flow hoods can be divided into two types: vertical unidirectional flow and horizontal unidirectional flow. Vertical unidirectional flow can effectively prevent external air pollution from entering the working area, while horizontal unidirectional flow is more suitable for large-area clean workshops. 3. Importance and role of laminar flow hood The application of laminar flow hood in the GMP pharmaceutical industry is mainly to maintain a highly clean environment in the drug production process. Through high-efficiency air filtration system and reasonable airflow organization, it can minimize particles and microorganisms in the air, thereby reducing the risk

Create a comfortable environment conducive to work for medical staff, and meet the strict requirements of the surgical process on air temperature, humidity, wind speed, freshness, cleanliness, noise, etc. The operating room building has strict divisions of clean area, quasi-clean area, and general area, with clear flow direction and rigorous plane functional area. Let’s talk about the role of the air shower room of the hospital purification project. As follows: 1. Low bacterial count in the operating room. 2. The indoor temperature of the comfortable air flow can be adjusted between 25℃ and 65%. 3. The positive pressure airflow of 25Pa in the operating room prevents the entry of external pollution. 4. The air in the operating room is fresh and clean, and the working environment is comfortable. 5. In laminar flow operating rooms, there is generally no need to use physical or chemical methods for disinfection, which saves labor and avoids the influence of bad air. 6. The role of the air shower room is to reduce the amount of dust brought into the clean room, ensure the cleanliness of the clean room, and will not cause secondary environmental pollution. 7. The air shower  is where the cleaned dust particles

In the field of biomedicine, air quality control is crucial. As an advanced air purification equipment, the gel seal HEPA filter is widely used in the purification end of various advanced sealed spaces due to its excellent performance and efficient filtering ability. This article will analyze in detail the application of gel seal HEPA filter in the field of biomedicine. 1. Principle and structure of gel seal HEPA filter.  The gel seal HEPA filter is mainly composed of ultra-fine glass fiber filter paper, jelly glue and metal frame. The core part is ultra-fine glass fiber filter paper, which has extremely high filtration efficiency and can effectively remove particulate matter and microorganisms in the air. Jelly glue is used for sealing to ensure the air tightness and reliability of the filter. 2. Characteristics of gel seal HEPA filter   1) High filtration efficiency: Using ultra-fine glass fiber filter paper as the filter material, Gel seal HEPA filter has extremely high filtration efficiency, which can filter out more than 99.97% of particulate matter and microorganisms in the air to ensure air quality. 2) Excellent sealing performance: Jelly glue sealing technology ensures that the filter forms an airtight and airtight sealing effect in the aluminum tank, preventing air leakage and improving filtration efficiency. 3) Wide range

In the field of modern scientific research and pharmaceuticals, accuracy and safety are two indispensable elements in the experimental process. In order to solve this problem, negative pressure weighing rooms came into being. It not only provides scientists with a safe experimental environment, but also ensures the accuracy of weighing. This article will take you to a deep understanding of what a negative pressure weighing room is, its importance and its application in various industries. 1. What is a negative pressure weighing room? The negative pressure weighing room is a safety device designed for sensitive powder materials and harmful dust. It is mainly used for accurate weighing of samples under a controlled environment. It effectively prevents dust leakage and pollution by generating a pressure difference (ie, negative pressure) lower than the external atmospheric pressure in the room, ensuring the safety of operators and the cleanliness of the laboratory. 2. Characteristics of negative pressure weighing rooms 1) High safety: The use of negative pressure technology effectively prevents harmful substances from leaking into the external environment, reducing the risk of occupational exposure. 2) Strong accuracy: The built-in precision balance, combined with a stable working environment, ensures the accuracy and repeatability of the weighing results. 3) Convenient operation:

When you are searching for issues about quality control, you may feel confused. Because sometimes you can see “quality assurance”. “quality control” and “quality assurance” sometimes are used in a mix. But actually, they are different and they shouldn’t be used with the same meaning. What is Quality Assurance (QA)? Quality assurance is to plan production activities & requirements and ensure these requirements will be fulfilled in the whole developing and manufacturing process. Take a new high-end watch production for example. QA has to do watch research, evaluate watch design, analyze watch sales and business, contact client’s specific requirements, etc. During these processes, QA can foresee the potential problems which haven’t yet happened to the watches. Then QA will pre-define the production processes and standards to prevent these problems. What is Quality Control (QC)? Quality control is a practical activity to inspect and test the products and the production process to ensure the finished products meet quality standards. Still take the new high-end watch production for example. QC inspect watches have been produced. QC finds and rejects defective products, like watches with scratches or painted the wrong color. These defective watches will be asked to rework to ensure the goods
