During the test, a variety of vessels and materials are needed to test them. In order to improve the safety of the staff, a group of transparent protective windows with operation ports are usually slidably installed on the front end face of the cabinet. In actual application, the operator puts both hands into the operation port to realize the transmission prevention test of infectious materials.

[0003] For example, the existing application number CN201921692344.8 discloses a biological safety cabinet, including a bracket and a cabinet fixed on the bracket, an operating room with a clean workbench opened on one side is provided in the cabinet, an ultraviolet lamp and a lighting lamp are provided in the operating room, a glass door is provided at the opening of the operating room, the glass door is connected to the opening of the operating room by sliding up and down, the glass door is movably and fixedly connected to the front wall of the cabinet through a motor, an air suction port is provided above the cabinet, the air suction port is connected to the air outlet duct, a filter and an exhaust fan are provided at the air suction port, a height sensor is provided on the glass door, a pressure sensor is provided on the filter, a timer is provided in the control panel, an air pressure sensor is provided in the cabinet, and an alarm device is also provided on the cabinet, which is connected to the height sensor, the pressure sensor, the timer and the air pressure sensor.
