1. Basic Definition and Core Functions
Also known as laboratory animal laboratory, it is a professional and standardized research facility specially designed for the rearing, breeding, observation and experimental operation of laboratory animals. It serves as a fundamental platform for scientific research in life science, medicine, pharmacy, agronomy and other disciplines.
Different from ordinary laboratories, it is equipped with systematic capabilities including environmental regulation, microbial prevention, personnel and material flow control, as well as temperature, humidity and cleanliness adjustment, creating a stable, controllable and traceable experimental environment.
Adopting professional ventilation purification, disinfection and sterilization, isolation protection and environmental monitoring technologies, the laboratory effectively reduces the adverse impacts of bacteria, fungi, parasites, dust and other exogenous contaminants on experimental animals. It minimizes environmental interference on experimental data, maintains steady physical conditions of animals, and guarantees authentic, accurate, repeatable and reliable experimental results, providing solid scientific support for research, drug testing and technological development.

2. Main Application Scope
Widely applied in basic research, pharmaceutical development, agricultural science, academic education and safety inspection, it acts as an important platform for interdisciplinary studies.
Basic Medical Research: Explore disease mechanisms, establish pathological models, study physiological functions, genetic experiments and immune responses, offering theoretical and experimental evidence for clinical medical advancement.
Biological and Veterinary Research: Conduct studies on animal physiology, pathology, microbiology and parasitology. It also supports livestock disease prevention, epidemic detection, veterinary drug development and efficacy verification.
Agricultural Scientific Research: Carry out experiments on crop resistance, feed development and safety inspection, livestock breed improvement, biological agent research and cultivation technology optimization.
Drug Research and Toxicology: Perform pharmacological tests, efficacy verification, toxicity detection and safety assessment for new drugs, as well as toxicological tests for health food and cosmetics. It is an essential site for pre-market drug safety evaluation.
Education and Skill Training: Provide practical training venues for medical, agricultural and bioengineering majors, cultivating professional research and technical talents.

3. Classification System Based on Microbial Control
Laboratories are classified into open system, barrier system and isolation system according to microbial control standards and protection levels.
Open System: Basic-level experimental space maintained by regular ventilation and disinfection. Suitable for common-grade laboratory animals and basic experiments with relatively low microbial control requirements.
Barrier System: Widely-used enclosed standardized space. Equipped with air filtration, strict disinfection, access management and pressure difference control, it builds a relatively sterile environment. It is applicable to rearing clean-grade and Specific Pathogen Free (SPF) animals for pharmaceutical and pathological research.
Isolation System: Highest-level sterile protection facility. With fully enclosed structure and multi-layer air purification, it forms an almost contaminant-free environment. It is used for germ-free animals, gnotobiotic animals and purebred species, catering to cutting-edge biological research and high-precision pathogenic studies.

4. Core Facilities and Layout Specifications
Complete functional facilities include breeding rooms, observation rooms, dissection laboratories, dedicated operation rooms, disinfection buffer rooms, material storage rooms and waste disposal rooms, covering the whole process of animal raising, observation, experiment, analysis and waste treatment.
The layout follows the principles of clear zoning, separation of clean and polluted areas and independent circulation routes to avoid cross contamination. The space is divided into clean area, buffer area and contaminated area. Separate passages are set for staff, animals, clean supplies and waste, thoroughly preventing cross-infection between humans and animals.

5. Operation and Management Requirements
Strict daily maintenance, environmental monitoring and standardized management are required. Key indicators such as cleanliness, temperature, humidity, ventilation frequency, pressure difference and microbial concentration are monitored in real time.
Staff must receive pre-job training and follow strict disinfection and aseptic operation rules. Laboratory animals are raised, quarantined and traced in standardized ways. Regular environmental disinfection, equipment maintenance and data recording are implemented to ensure animal health, genetic stability and reduce experimental errors.
6. Core Value and Significance
As indispensable infrastructure for biomedical research, biological safety testing, biological product manufacturing, agricultural innovation and public health prevention, it provides favorable living and experimental conditions for animals. It ensures precise, repeatable and traceable research and testing data.
Standardized animal laboratories support high-end scientific innovation, new drug research and achievement transformation for universities, research institutions and pharmaceutical enterprises, and play a vital role in promoting life science progress, medical upgrading and public health security.
