What is the use of a fume hood?

In the laboratories for working with harmful substances, exhaust cabinets are used. They are used in the implementation of chemical and analytical studies that are associated with the emergence and spread of hazardous to human health toxic fumes and gases.

The exhaust laboratory cabinet is used in conjunction with an external exhaust system. Its functioning is aimed at the forced elimination of hazardous substances from the working area by means of external drawing. This technique is used in laboratories of various profiles.

The hood is the most expensive and basic piece of furniture for the food, chemical and medical laboratory. It is with him that all complex tests and tests are involved. But the most important thing is that it provides the employees of the organization with safe conditions for the performance of laboratory work. In addition, the hood is a very complex product, because it is equipped, depending on the need and modification, a system of built-in supply and exhaust ventilation, electrical and plumbing devices, and some models have even a vacuum, air and gas lines.

To the largest group of this technology include cabinets equipped with an open-circuit hood. Guaranteed provision of labor zone safety for working personnel is carried out with the help of regular forced air sucking out of the open working chamber with its further emission into the atmosphere outside the laboratory premises through the ventilation system. If this group is considered from the point of view of the basic design carrier, then it can be divided into two components - fume hoods from LDPC (DPS, lacquered) and metal (lined with stainless or painted metal sheets of metal frames). Each of these types has its operational disadvantages and advantages, but in general their consumer properties are almost identical.

Considering in terms of cost fume hoods made of different materials, (exclude those in the finish of which stainless steel is used , since their cost will be much higher), the advantage will be the models from chipboard, because their cost is lower by about 20% Compared with metal ones. In addition to the financial component, the main difference between these types of technology is security. A metal exhaust hood is more aimed at operation in conditions with increased fire hazard. With regard to mechanical and chemical endurance, the modern laminated coating of DPS is absolutely not inferior to the facing of painted metal.

Let's try to figure out what the choice of furniture is made of metal or from the chipboard for the laboratory. Basically it depends on the individual preferences and financial potential of the user. Some believe that the fume hood made of metal is more durable, and does not take into account the fact that the working period of furniture made of chipboard is 10 years. And with the proper attitude, it will not lose its appearance much longer. Proceeding from this, we can safely conclude that if you have the desire to save money and purchase a quality laboratory fume hood, safely opt for the furniture from the chipboard.
