1 المقدمة

The working principle of the biosafety cabinet is to pump the air out of the cabinet to keep the negative pressure in the cabinet and protect the staff through vertical air flow. The air in the cabinet also needs to be filtered by HEPA filters to protect the environment.

2. الأداء

• The 10° tilt angle design conforms to the ergonomic principle, and the operation experience is better;
• The shell is made of high-quality cold-rolled steel plate and electrostatic sprayed; the three sides of the safety cabinet operating area adopts a stainless steel (SUS304) integrated structure, and the internal cleanable parts are treated with 8mm large round corners for easy cleaning;
• Unique internal cavity safety negative pressure design, air curtain isolation, to ensure no leakage under normal use, 70% gas circulation, 30% exhaust laminar flow, in line with YYⅡ biological safety cabinet standards;
• The integrated working table adopts a tray structure, which is easy to remove and clean. There is a liquid collecting tank under the operation table and a sewage valve under it;
• Biosafety cabinet is equipped with filter blocking alarm, blower overload alarm, working window opening limit alarm system;
• Integrated sliding safety sliding door, which can be positioned arbitrarily, is easy to operate, and can be completely closed for sterilization;
• Using ultra-high-efficiency air filter with a filtration efficiency of 99.999% (m particles). The filter membrane material is made of borosilicate glass fiber without partitions;
• The front window and germicidal lamp chain design: when the front window is raised, the germicidal lamp turns off;
• The bracket-type safety cabinet, the bracket and the upper box can be separated, which is convenient for transportation and positioning;
• Biosafety cabinet has the function of parameter memory and call recovery for protection due to power failure and data loss in crash state.
