Product Description The structure of biological safety cabinetBiological safety cabinets generally consist of two parts: a box body and a bracket. The box body mainly includes the following structures:1. Air Filtration SystemThe air filtration system is the most important system to ensure the performance of this equipment. It consists of a driving fan, an air duct, a circulating air filter and an external exhaust air filter. Its main function is to continuously make clean air enter the studio, so that the downdraft (vertical airflow) flow rate in the work area is not less than 0.3m/s, and the cleanliness in the work area is guaranteed to reach 100 grades. At the same time, the external exhaust flow is also purified to prevent environmental pollution.The core component of the system is the HEPA filter, which uses a special fireproof material as the frame, and the frame is divided into grids by corrugated aluminum sheets, which are filled with emulsified glass fiber sub-particles, and the filtration efficiency can reach 99.99%~100%. The pre-filter cover or pre-filter at the air inlet allows the air to be pre-filtered and purified before entering the HEPA filter, which can prolong the service life of the HEPA filter.2. External exhaust air box systemThe outer exhaust box system consists of an outer exhaust box shell, a fan and an exhaust duct. The external exhaust fan provides the power for exhausting the unclean air in the working room, and it is purified by the external exhaust filter to protect the samples and experimental items in the cabinet. The air in the work area escapes to protect the operator.3. Sliding front window drive systemThe sliding front window drive system is composed of front glass door, door motor, traction mechanism, transmission shaft and limit switch, etc. The main function is to drive or pull each door shaft, so that the front glass door is in the normal position during the operation of the equipment.4. The lighting source and UV light source are located on the inside of the glass door to ensure a certain brightness in the work room and to sterilize the table and air in the work room.ApplicationThe biological safety cabinet can prevent the occurrence of aerosols containing dangerous or unknown biological particles during the experimental operation and processing.Dissipative box-type air purification negative pressure safety device. It is widely used in microbiology, biomedicine, genetic engineering, biologicalIn scientific research, teaching, clinical inspection and production in the fields of laboratory biosafety, it is the most basic protective barrier in laboratory biosafety.Safety protection equipment.
