Application scope: Biosafety cabinet is widely used in medical and health care, disease prevention and control, food hygiene, biological pharmacy, environmental monitoring, higher education institutions and chemical experiments, virus experiments and other high-risk situations. Biosafety devices are biosafety devices used in microbiology, biomedical, biosafety laboratories and other laboratories.It adopts advanced air purification technology and negative pressure box design, which can protect the environment, personnel and samples and prevent the diffusion of harmful suspended particles and aerosols.It provides safety protection for operators, samples and cross-infection between samples and the environment. It is the most basic safety protection equipment in the first-level biological safety protective barrier of the laboratory. Features description: The executive standard of the conflict: YY 0569-2005 and is in compliance with us NSF/ ans149-2002 and European en12469:2000 standards. Have unique design of inner cavity safety negative pressure gas episodic isolation, to ensure the normal use don't leak, 70% gas cycle, 30% exhaust way of laminar flow, accord with YY0569-2005 grade Ⅱ biological safety cabinet standard; To comply with the principle of ergonomics 10 ° Angle design, operation experience is better; The outer box is made of high quality cold rolled steel and is sprayed with static electricity. The three sides of the safety cabinet operation area adopt stainless steel (SUS304) integrated structure, and the cleaning part inside is treated with 8mm large round Angle, which is convenient for cleaning. The work table with integral shape adopts pallet structure and is easy to remove and clean. The filter is equipped with pre-failure and damage and blocking alarm technology. The fan overload alarm is provided. When the opening height of the front window of the safety cabinet exceeds the set height, when the flow velocity of the downdraft and inflow flow velocity of the safety cabinet fluctuates more than 20% above its nominal value, the interlock system starts alarm prompt. Two ULPA super-efficient filters are standard in the project, which can reach 99.999% of the blocking efficiency according to 0.12 million particles. Borosilicate glass fiber without partition is used as filter material. Lying integrated sliding safety door, can be arbitrarily positioned, easy to operate, and can be closed completely for sterilization. The front window and sterilization lamp interlock design: when the current window is raised, the sterilization lamp is put out; The table supports the safety cabinet, the bracket and the upper box body can be separated, easy to carry and in place. Is due to power failure, crash status data loss and protection of parameter memory, call recovery function.
