The modular laboratory adopts factory-prefabricated clean panels assembled in a modular way and can be flexibly divided according to experimental functions into a sterility testing area, a physicochemical analysis area, a sample storage area, and a buffer/gowning area. Personnel and material flow routes are rationally planned to avoid cross-contamination. It supports customized cleanliness classes including Class 100,000, Class 10,000, and Class 100, and is equipped with a complete automatic control system for laminar flow purification, constant temperature and humidity, negative-pressure ventilation, and waste gas and liquid treatment. Walls and floors feature seamless coved finishes, are resistant to acid and alkali corrosion, and are easy to clean and disinfect. The overall construction period is short, and the laboratory can be easily dismantled and reassembled, with convenient future expansion and renovation. It comes with integrated supporting facilities such as laboratory workbenches, fume hoods, and intelligent information terminals, and strictly complies with construction standards for medical testing laboratories and biological laboratories. We provide one-stop services covering layout design, enclosure construction, and purification equipment installation and commissioning. It is widely applicable to hospital clinical laboratories, third-party testing institutions, biomedical R&D, and university research laboratories, and is also suitable for the implementation of domestic and international cross-border medical laboratory projects.
