Stem cell technology serves as a core pillar in regenerative medicine and precision medicine, and the safety and standardization of its research and application directly depend on the construction level of specialized laboratories. The construction of stem cell laboratories differs from that of ordinary biological laboratories, requiring consideration of four core dimensions: clean environment control, biosafety protection, equipment precision assurance, and a quality management system. It must strictly adhere to relevant national and industry standards, achieving standardization throughout the entire process from site planning to operation and maintenance management. This article, based on relevant industry standards, elaborates on the core points and implementation paths for stem cell laboratory construction, providing a practical construction reference for research institutions, medical institutions, and enterprises.

Animal laboratories are specialized facilities used to raise laboratory animals and conduct animal experiments. Their design quality directly affects the accuracy of experimental results, the health and welfare of animals, and the biosafety of researchers.

At the forefront of biomedical research and disease control, biological laboratories are not only "containers" for scientific exploration, but also "fortresses" against potential biological risks. The cleanliness, stability, and safety of their internal environment are directly related to the accuracy of experimental results and the safety of researchers.

In the daily operation of modular cleanrooms, unstable differential pressure is a common and challenging problem. Stable differential pressure is a key indicator for maintaining cleanliness and preventing cross-contamination. Fluctuations can not only affect product quality but also lead to the failure of the entire purification system. This article will systematically analyze the four main causes of unstable differential pressure from a practical operation and maintenance perspective and provide a set of on-site troubleshooting methods.

Modular cleanrooms, with their advantages of rapid installation, adjustable layout, and controllable cost, are widely used in fields with strict requirements for environmental cleanliness, such as pharmaceuticals, electronics, and food. Although large-scale on-site construction is not required, achieving a stable and compliant clean environment necessitates consideration of multiple core conditions, including preliminary planning, environmental control, structural materials, equipment configuration, construction acceptance, and operation and maintenance management. Each of these factors directly determines the effectiveness and compliance of the cleanroom.
