1. Horizontal laminar flow ultra-clean workbench: It is a versatile local clean workbench, which is widely used in electronics, national defense, precision instruments, instrumentation, pharmaceutical industry, etc. 2. Vertical laminar flow ultra-clean workbench: The vertical unidirectional flow ultra-clean workbench is widely used in areas requiring local cleanliness. Laboratory, biopharmaceutical, optoelectronic industry, microelectronics, hard disk manufacturing and other fields. The vertical unidirectional flow ultra-clean workbench has the advantages of high cleanliness, can be connected into an assembly production line, low noise, and mobility. In short, the current workbench can meet your experimental needs. All you have to consider is the airflow pattern (according to your experiment to see which type of air supply has the least effect on your experiment): that is, vertical or horizontal. Generally vertical. The vertical air supply is vertical downward blowing, vertical manifold, quasi-closed table, which can effectively prevent the external confluence and the odor of the operation from stimulating the human body. Also ensure that the air flow can pass through without obstruction, if it is in the workbench Put the microscope, the air flow of vertical air supply will be blocked by the microscope, it is better to choose the horizontal, but the general experiment uses vertical, and the glass door generally moves up and down. Levels sometimes affect the flame of alcohol lamps. To put it bluntly, there is no obvious pros and cons of the two types of air supply, and it is most important to choose the appropriate type according to the experiment.
