A Comprehensive Analysis of Construction Standards for DNA Testing Laboratory Purification Projects

2025.01.24
In the current era of rapid development of gene science, DNA testing laboratories undertake important tasks such as disease diagnosis and genetic analysis. A high - standard purification project is a key prerequisite for ensuring the accuracy and reliability of DNA testing results. As a professional purification equipment manufacturer, Guangzhou Cleanroom Construction Co., Ltd. will deeply analyze the construction standards for DNA testing laboratory purification projects for you today.

I. Air Purification Standards

1. High - efficiency Filtration System: DNA testing experiments are easily interfered by tiny particles and microorganisms in the air. Therefore, high - efficiency particulate air (HEPA) filters need to be equipped. Generally, the filtration efficiency for particles with a particle size of ≥ 0.3μm should reach over 99.97% to effectively intercept pollutants such as dust, bacteria, and viruses, creating an ultra - clean air environment for experiments.
2. Reasonable Airflow Organization: Unidirectional flow or turbulent flow airflow organization methods are adopted. Unidirectional flow can form parallel and uniform airflow, which is more effective in discharging pollutants; turbulent flow is suitable for some areas with slightly lower airflow requirements. At the same time, the positions of air supply outlets and air return outlets are reasonably set to avoid airflow dead corners and ensure uniform air purification in the room.

II. Ground and Wall Treatment Standards

1. Selection of Ground Materials: The ground needs to have the characteristics of wear resistance, corrosion resistance, anti - static properties, and easy cleaning. Epoxy self - leveling floors are commonly used. Their seamless and flat surfaces can effectively prevent dust accumulation and are convenient for cleaning and disinfection, meeting the strict requirements of DNA testing laboratories.
2. Requirements for Wall Materials: Color steel plates or antibacterial wall panels can be selected for the walls. Color steel plates have the advantages of fire resistance, moisture resistance, and high strength. Antibacterial wall panels can inhibit the growth of bacteria and reduce the risk of microbial contamination. Both are easy to wipe and maintain, ensuring the cleanliness of the laboratory walls.

III. Disinfection and Sterilization Standards

1. Regular Disinfection Measures: The laboratory should formulate strict disinfection plans. After the end of experiments every day, the experimental countertops, floors, instrument equipment, etc. need to be comprehensively disinfected. Chemical disinfectants can be used for wiping, such as 75% alcohol, chlorine - containing disinfectants, etc., and appropriate disinfection methods are selected for different items.
2. Configuration of Sterilization Equipment: For some key experimental utensils and consumables, high - temperature and high - pressure sterilization treatment is required. Professional autoclaves are equipped to ensure that the sterilization effect reaches the sterile standard and prevent cross - contamination from affecting DNA testing results.

IV. Personnel and Item Purification Standards

1. Personnel Purification Process: Personnel entering the laboratory need to go through a strict purification process, including steps such as changing into clean work clothes, hand - washing, disinfection, and air shower. The air shower room can effectively remove dust and microorganisms on the surface of personnel's clothing, avoiding the introduction of pollutants into the experimental area.
2. Item Purification Requirements: All items entering the laboratory, such as reagents, samples, instruments, etc., need to be surface - cleaned and disinfected. For external items, they also need to enter through a pass - through window. The two - side doors of the pass - through window need to be interlocked to prevent air convection from causing pollution.
