How to choose the correct Lab Storage Cabinet exhaust?
In the chemical experiment process, often produce a variety of unpleasant, corrosive, toxic or explosive gas. Laboratory equipment manufacturers to remind you: these harmful gases if not promptly excluded from the outdoor, it is necessary to cause indoor air pollution, affecting the health and safety of the experimental staff; affect the accuracy of equipment and service life, therefore, the laboratory storage cabinet is the laboratory design An indispensable component. In order to allow laboratory staff not to inhale or swallow some toxic, pathogenic or toxic chemicals and organisms, the laboratory should be well ventilated. In order to prevent some of the vapor, gas and particulates (smoke, soot, dust and gas suspension) inhalation, pollutants must be used to remove the laboratory storage cabinet, hood, local exhaust method.
There are two types of chemical laboratory ventilation, that is, local exhaust and the whole room ventilation. Local exhaust is immediately after the occurrence of harmful substances discharged, this way can be a small amount of air emissions from a large number of harmful substances, energy and effect is good, is to improve the existing laboratory conditions feasible and economical methods, it may Is the best way to adapt to the new laboratory ventilation. For some experiments can not use local exhaust, or local exhaust can not meet the exhaust requirements, the use of full room ventilation.
The laboratory storage cabinet is one of the most commonly used local exhaust equipment in the laboratory, and his performance depends mainly on the speed of movement of the air through the laboratory storage cabinet. Factors that affect the front speed and air movement are vortex, the inlet shape of the cabinet, the heat load, the mechanical action, the vent hole design and the anticoagulant. In addition, it is related to its ability to prevent fire, corrosion resistance, ease of cleaning, and the ability of contaminants to collect certain contaminants before entering the exhaust system. It is generally believed that laboratory Lab Storage Cabinet in the laboratory should be able to accommodate flammable liquids and gases, and that structural materials should have a few minutes of fire resistance to keep the laboratory storage cabinet complete and timely.
To date, in most laboratories, Lab Storage Cabinet are an important component that is very eye-catching and frequently used. Since the eighties did not, when the epoxy resin gradually replaced the cement asbestos, etc. become the mainstream of the laboratory storage cabinet and incorporated into the industry standard, the manufacturers have also committed to improving the design of the countertop to meet the research laboratory Corrosion resistance, heat resistance and load resistance requirements. Therefore, the current countertop can have many different types, colors and additional safety and aesthetic functions to choose from, to the various laboratories on the efficiency, accuracy, comfort and accuracy of different requirements, provides a variety of options.
Precise / novel design
In general, the new Lab Storage Cabinet are often in accordance with the new equipment, space reconfiguration or a comprehensive renovation to design. Due to the characteristics of the R & D laboratory, the design of the countertop board needs to be considered with some flexibility (R & D laboratories have an average life expectancy that is to be reconstructed every three to five years). Therefore, in the initial planning, we should consider the future needs to select the appropriate countertops (and the bottom cabinet), so in the long term can only achieve the purpose of saving costs.
