Objective To test the function and evaluate the safety of the self-developed biosafety cage changing workbench. Methods According to the criteria of YY 0569-2011 "Class II Biological Safety Cabinet" and RB/T 199-2015 "Laboratory Equipment Biosafety Performance Evaluation Technical Specifications", we detected the various performance indicators of the cage changing workbench (HT-1303), which was independently developed and produced by Shenzhen Hongteng Biological Technology Co., LTD, and evaluated the safety and validity. Results The appearance integrity and stability of the main body of the biosafety cage changing workbench, the cleanliness of the working area, the velocity of the inflow airflow, the velocity of the descending airflow, the illuminance, the noise level, the airflow direction, the high-efficiency particulate air filter were at good condition, reaching the standards of level II biological safety cabinet. The airtightness of the contaminated goods recovery cabin and the sterilization chamber of utensil surface was good, but the size and quantity of the sterilized cage box need to be further improved. Conclusion The biosafety cage changing workbench developed by our team can be operated properly in whole. It can complete the replacement of individually ventilated cages in this workbench under negative pressure environment. Our workbench also can ensure the safety of operators, environment and experimental subjects.
