Standard Humidity in Animal Laboratories: Guangzhou Cleanroom Construction Co., Ltd. Helps Create a Suitable Environment for Animal Survival and Experiments
2025.03.19
Animal laboratories, as crucial places for conducting various animal experiments, have environmental conditions that play a vital and decisive role in the health, physiological state of experimental animals, and the accuracy of experimental results. Among these, humidity is an important environmental factor that cannot be ignored. As a professional constructor, Guangzhou Cleanroom Construction Co., Ltd. deeply understands and strictly adheres to the standard humidity requirements for animal laboratories during the construction process, and is committed to creating an ideal experimental environment for scientific researchers.
I. The Significant Impact of Humidity on Experimental Animals
A. Impact on Animal Health
Appropriate humidity helps maintain the normal physiological functions of experimental animals. Excessively high humidity will make the animals' perceived body temperature rise, and it will be difficult for them to dissipate heat, leading to heat stress reactions in animals, a decrease in immunity, and an increased susceptibility to diseases. For example, in a high-temperature and high-humidity environment, mice are prone to symptoms such as difficulty breathing and decreased appetite, and microorganisms like bacteria and molds are more likely to breed, increasing the risk of animals getting sick. Conversely, too low humidity will dry out the respiratory mucosa of animals, causing respiratory diseases. For instance, rats may experience problems such as bleeding and cracking of the nasal cavity and respiratory mucosa.
B. Interference with Animal Behavior and Physiological Rhythms
Changes in humidity can affect the behavior and physiological rhythms of animals. Some animals are sensitive to humidity. When the humidity is not suitable, their activity levels, food intake, and sleep time will all change. For example, rabbits will become restless and less active in a high-humidity environment; while in a low-humidity environment, their fur will become rough, and they will increase grooming behavior. These changes in behavior and physiological rhythms may interfere with the accuracy of experimental results and cause deviations in experimental data.
C. Impact on the Accuracy of Experimental Results
For some experiments that require precise control of the physiological state of animals, fluctuations in humidity may have a significant impact on the experimental results. In drug research and development experiments, the physiological state of animals has an important influence on the processes of drug absorption, metabolism, and excretion. Humidity changes may alter the physiological state of animals, thus affecting the evaluation of drug efficacy. For another example, in genetic experiments, inappropriate humidity may affect the gene expression and genetic stability of animals, resulting in unreliable experimental results.
II. Standard Humidity Requirements for Different Types of Experimental Animals
A. Rodents
Rodents such as mice and rats are the most commonly used experimental animals in animal laboratories. The suitable relative humidity range for them is generally between 40% and 70%. Within this humidity range, the physiological functions of rodents can be normally exerted, and their health conditions are good. For example, when cultivating and researching transgenic mice, maintaining appropriate humidity helps with the growth, development, and reproduction of the mice, ensuring the smooth progress of the experiment.
B. Rabbits
Rabbits have relatively strict requirements for humidity. The suitable relative humidity is generally between 40% and 60%. Excessively high humidity is likely to cause skin diseases and respiratory diseases in rabbits because rabbits have long and dense fur, and bacteria and fungi are likely to breed in a high-humidity environment. While too low humidity may dry out the skin and respiratory mucosa of rabbits, causing discomfort.
C. Dogs and Primates
The suitable relative humidity range for dogs is usually between 30% and 70%, and for primates such as rhesus monkeys, the suitable relative humidity is generally between 40% and 65%. These larger experimental animals have a relatively wider adaptability range to humidity, but it is still necessary to keep the humidity within an appropriate range to ensure their health and the accuracy of the experiments. For example, when conducting cardiovascular disease experiments on dogs, appropriate humidity helps maintain the normal function of the dog's cardiovascular system and reduces the interference of environmental factors on the experimental results.
III. Professional Measures Taken by Guangzhou Cleanroom Construction Co., Ltd. for Humidity Control in Animal Laboratories
A. Precise Design and Planning
During the design stage of the animal laboratory, the professional team of Guangzhou Cleanroom Construction Co., Ltd. will fully consider the humidity requirements of different types of experimental animals and the functional layout of the laboratory. Through comprehensive analysis of factors such as the laboratory's area, spatial structure, and heat generation of equipment, the capacity and quantity of the required humidity control equipment are accurately calculated. For example, for a large comprehensive animal laboratory, according to the types and quantities of animals raised in different areas, the humidity control areas are reasonably divided, and corresponding humidity control equipment is equipped for each area to ensure that the humidity in each area can meet the standard requirements.
B. Selection of Advanced Humidity Control Equipment
Guangzhou Cleanroom Construction Co., Ltd. cooperates with many well-known equipment suppliers and selects advanced humidity control equipment, such as intelligent humidity control systems, dehumidifiers, humidifiers, etc. These devices are equipped with high-precision humidity sensors and intelligent control algorithms, which can monitor and adjust the humidity of the laboratory in real-time. The intelligent humidity control system can automatically start the dehumidification or humidification function according to the set humidity range to ensure that the humidity remains stable within the standard range. At the same time, Guangzhou Cleanroom Construction Co., Ltd. will select appropriate installation locations for the equipment according to the actual situation of the laboratory to ensure the effect of humidity control.
C. Strict Control of Construction and Installation Quality
During the installation and construction process of the humidity control equipment, Guangzhou Cleanroom Construction Co., Ltd. operates strictly in accordance with the design requirements and construction specifications. Ensure that the equipment is firmly installed and tightly connected to avoid problems such as water leakage and air leakage. For the installation of ventilation ducts and humidity sensors, strict quality inspections will also be carried out to ensure the normal operation of the ventilation system and the accuracy of humidity monitoring. For example, when installing a humidifier, ensure that the spray port of the humidifier is in a reasonable position to avoid the water mist directly spraying on the animals or experimental equipment.
D. Comprehensive After-sales Service and Maintenance
After the animal laboratory is completed, Guangzhou Cleanroom Construction Co., Ltd. provides customers with comprehensive after-sales service and maintenance solutions. Regularly inspect and maintain the humidity control equipment, including cleaning the equipment, replacing the filters, calibrating the humidity sensors, etc., to ensure the normal operation of the equipment and the accuracy of humidity control. At the same time, the professional technicians of Guangzhou Cleanroom Construction Co., Ltd. will regularly monitor and analyze the humidity situation of the laboratory, and promptly discover and solve potential problems. If abnormal humidity fluctuations are found, they will respond quickly and take effective measures to adjust to ensure that the humidity of the laboratory always meets the standard requirements.
IV. Other Precautions for Humidity Control
A. Regular Monitoring and Recording
It is recommended that users of animal laboratories regularly monitor the humidity of the laboratory and keep records. Through the analysis of humidity data, the change rules of humidity can be understood, and potential problems can be discovered in a timely manner. Professional humidity recorders can be used to automatically record humidity data at regular intervals and generate humidity change curves, which is convenient for data analysis and trend prediction.
B. Personnel Training and Management
Conduct training on humidity control for laboratory staff so that they understand the importance of humidity for experimental animals and experimental results, as well as how to correctly operate and maintain the humidity control equipment. At the same time, establish a complete laboratory management system, clarify the responsibilities and operation specifications of staff in humidity control, and ensure the effective implementation of humidity control work.
C. Coordinated Control with Other Environmental Factors
The control of humidity needs to be coordinated with other environmental factors in the laboratory, such as temperature and ventilation. For example, while adjusting the humidity, pay attention to changes in temperature to avoid the temperature being too high or too low due to humidity adjustment. A good ventilation system can help the humidity control equipment play a better role, and timely discharge excess moisture or replenish dry air.
