The difference between vertical and horizontal flow hoods
The difference between vertical and horizontal flow hoodsThe purification workbench is a basic and important equipment in the laboratory. A purification workbench is used to purify contaminated air inside biology and chemistry laboratories. These purification workbenches are mainly divided into two categories: vertical purification workbench and horizontal purification workbench. Today, we will experience the differences between these two different types of purification workbenchs.We need to understand the two main types of clean benches: vertical clean benches and horizontal hoods. Vertical laminar flow: The air in the room enters through a special air intake form. There will be a blower directing it toward a high-efficiency particulate air filter, or HEPA. Then, some of the air is expelled through the vents, eventually leaving the area completely. After the air is filtered by HEPA, it will flow back into the room again. Horizontal Laminar Flow: These horizontal decontamination benches are often designed to resemble a bench. On the work surface, the pre-filter will draw air into the HEPA space. Air should circulate smoothly from the HEPA to the entire work surface. In life, laminar flow is used in many situations, such as to circulate the air in the room, ensure that patients are not exposed to any form of pollutants, and prevent emitted pollutants from entering the bodies of other patients and affecting other patients; and For example, burn patients cannot risk exposing the affected area to any polluted environment. However, both vertical and horizontal clean benches are suitable for use in work labs. This equipment will maintain a safe and non-toxic environment within the laboratory. |
