Regardless of changes in its appearance, its internal performance must have the following elements: 
 ** ** Steplessly movable window frame with one piece ABS material, the balance of the window glass can be easily moved, and no noise. Composite window with 6mm toughened safety glass, the vertical height of the maximum opening 900mm, is the ideal height space experiments. 
 ** Spoiler ** three-stage diversion system using 5mm import Kang Beite plate, with good acid properties. Different proportion of three-stage diversion cabinet can easily absorb the harmful gas emissions, the total elimination of exhaust dead, ensure that no residual gas. 
 Operating table ** ** EPOXY corrosion, impact resistance, excellent high temperature performance, both the U.S. and the Netherlands Wilsonart all the benefits of Trespa, the first choice for today's laboratory table, were surrounded by a thick file of 45 waterside ° angled, match exactly with the operating surface with a solution to prevent the leakage function. 
 ** PC ** fixture synthesis injection produced high-quality PC, forming one. To fix the guide plate, convenient, beautiful, easy to disassemble for maintenance and cleaning guide plate convenience, but also the future acquisition of synthetic frame and prepare a positioning base. 
 Balance weight Type weight ** weight ** weight part of a balanced design, the windows are free to stay at any height. Fully enclosed design with a hidden bearing pulley so that the window vertically Brisk lubrication. 
 ** ** Electrical circuits socket in the use of international standard, for a variety of instruments plug. Circuit uses touch-button control system, there is leakage, overload, under equal protection, provide considerable security. Safe use of hidden lighting 30w lights, to ensure that operating room brightness 400Lux. 
 ** On the cabinets, under cabinet, panel ** 1.2mm cold rolled steel sheet products of Baosteel bending produced by phosphating, pickling, external epoxy powder coating, high temperature bake curing, adhesion , surface hardness and strong acid properties. Under the cabinet-in-one with excellent stability and load-bearing of. Imported high quality detachable hinge quick, easy disassembly and maintenance, so that both drugs under the counter cabinets, solvent storage cabinets and other functions. 
 Ventilation parameters ** ** 
 Under the fume hood and the configuration selected fans of different specifications, the following parameters 
 ** Suction capacity: 1200 m3 / h 1600 m3 / h 3000 cubic meters / hour 
 ** Surface wind speed: 0.5m / s (usually required, the general non-toxic pollutants 0.25-0.3 m / s; toxic or dangerous pests 0.4-0.5 m / s; a small amount of toxic or radioactive 0.5- 0.6 m / s; gas tilting to 0.5 m / s particulate is 1 m / s) 
 ** Exhaust outlet diameter: 250 mm
