Embodiment 1

[0025] Please refer to figure 2 , a safe and sealed biological safety cabinet, including a cabinet body 10, and the cabinet body 10 is fixed on a bracket 20. The cabinet is provided with an exhaust system, a filter system, a workbench, etc., which are common technical features in the prior art, and will not be described in detail here.

[0026] Please refer to image 3 ,Depend on image 3 It can be seen that a PCB board 30 is fixed by screws on the sealing board of the cabinet body 10 in the present invention, and the PCB board is a PCB board with a transfer function.

[0027] The front and back sides of the adapter PCB board 30 are respectively provided with corresponding adapters, and the adapters on the front and back are in one-to-one correspondence, and can be connected to external and internal wires respectively, further realizing the one-to-one correspondence between external wires and internal wires.

[0028] In order to achieve a better sealing effect, the transfe...

Abstract

The invention provides a biological safety cabinet with security seal, comprising a cabinet body, an exhaust system arranged in the cabinet body and a filter system, wherein the wires inside and outside of the cabinet body are connected by a transfer printed circuit board (PCB). The transfer PCB is fixed on the seal plate of the cabinet body through four screws and is sealed by silica gel. Compared with the fixed head connection mode of the traditional biological safety cabinet, the connection mode of the invention has the advantages that the assembly and disassembly are more convenient and the connection is more firm, thus enhancing the seal performance.

Description

technical field [0001] The invention relates to a biological experiment equipment, in particular to a safe and sealed biological safety cabinet. Background technique [0002] Aerosols may be generated when liquids or semifluids are manipulated in the laboratory, such as by shaking, pouring, stirring, or dripping a liquid onto a solid surface or into another liquid. Aerosols can be generated by streaking agar plates, pipetting cell culture flasks, centrifuging infected fluids, and performing animal manipulations. For these aerosols with a diameter of less than 5 microns and tiny liquids with a diameter of 5-100 μm, which cannot be seen by the naked eye, laboratory workers are usually unaware of their existence and may inhale or cross-contaminate other materials on the work surface. [0003] Biological safety cabinets are used to protect the operator, the laboratory environment and experimental materials from exposure to the above-mentioned operations when operating infectiou...
