Introduction of the Instrument With the development of modern biology technology, the biologic safety problem has drawn great importance to vast scientific and technical workers in biology field. The laminar clean bench is one of essential and widely applied basic facility in the biology technology researching, but its biologic safety and validity face severe challenge for the instant state of its main part HEPA (high-efficiency purifier).
Presently, as to the laminar clean bench widely used in inland, the user has difficulty in judging at the safety and validity of the HEPA. So, there are overdue services and invalid usages generally or to some extents exist in national college, junior college schools, and scientific research laboratories of research and application fields such as biology pharmacy. So, the safety and validity problem of the biologic technology are rather severe!
ZHICHENG ZHJH-C series of new type laminar clean bench tackles the users problem of monitoring the HEPA status. It can display the HEPA status of the laminar clean bench on LCD liquid crystal display screen full in Chinese, monitor the whole process, and design two functions of invalid acoustic-optic pre-warning and warning.
Additionally, automatic functions like real-time check, LCD wind speed display in fixed quantity and set the open and close time of the sterilizing lamp of ultraviolet rays randomly. The application of these series of technologies provides an invigorative solution for the problems, which has puzzled the biology field for years of overdue service and invalid usage of HEPA. The first 101 pieces ZHJH-1209C new type laminar clean bench won the bid in the bid invitation of animal cold chain project in the Agriculture Department, Xin Jiang corps on Nov.18th, 2004.
Major Technical Features 1 LCD large-screen liquid crystal display screen displays each working parameters Pattern reveals the humanized soft push controlling panel Display in full Chinese at HEPA state, whole-process monitoring, automatic acoustic-optic pre-warning and warning for invalid state The wind speed is adjustable at stepless, LCD indicates the actually measured wind speed, which ensures the wind speed in the operating room at an ideal state The open and close time of the blower and the UV sterilizing lamp can be willfully designed and automatically controlled Be provided with clock indicating function, the experimental time can be displayed accumulatively Equipped with high efficient air filtering system with preprocess filter Up and down sliding front window, which can be positioned freely Double side safe big screen window with wide viewpoint and good illumination High quality stainless steel box with smooth and easy-clean internal corner It has universal turning truckle and can move easily. It is also stable and reliable when fixed.
