In laboratories, fume hoods are used to work with harmful substances. They are used in carrying out chemical-analytical studies that are associated with the appearance and spread of toxic fumes and gases hazardous to human health.
Laboratory fume hood is used in conjunction with an external exhaust system. Its functioning is aimed at the forced elimination of hazardous substances from the working area through an external exhaust. This technique is used in laboratories of various profiles.
A fume hood is the most expensive and basic piece of furniture for the food, chemical and medical laboratories. It is with him that all complex tests and tests are associated. But the most important thing is that it provides the employees of the organization with safe conditions when performing laboratory work. In addition, a fume hood is a product that is very complex in terms of technical characteristics, because it is equipped, depending on needs and modifications, with a built-in supply and exhaust ventilation system, electric and plumbing devices, and some models even have vacuum, air and gas lines.
The largest group of this technology includes cabinets equipped with an open type exhaust circuit. Guaranteed to ensure the safety of the working area for workers by means of regular forced air suction from an open working chamber with its further release into the atmosphere outside the laboratory room through a ventilation system. If we consider this group from the point of view of the supporting basic structure, then we can distinguish two components in it - fume hoods made of LDPS (DPS varnished) and metal (sheathed with stainless or painted metal sheets). Each of these species has its own operational disadvantages and advantages, but in general their consumer properties are almost identical.
Considering fume hoods made of various materials from a cost point of view (excluding those that use stainless steel to finish , because their cost will be much higher), models made of chipboard will benefit, because their cost is about 20% lower compared to metal. In addition to the financial component, the main difference between these types of equipment is safety. A metal fume hood is more suitable for use in environments with increased fire hazard. As for mechanical and chemical endurance, the modern DPS laminated coating is absolutely not inferior to the lining of painted metal.
Let's try to figure out what the choice of metal furniture from or from chipboard for the laboratory is based on. This mainly depends on the individual preferences and financial potential of the user. Some people think that a fume hood made of metal is more durable, but they do not take into account the fact that the working life of chipboard furniture is 10 years. And with the proper attitude, she will not lose her appearance for much longer. Based on this, we can safely conclude that if you have a desire to save money and purchase a high-quality laboratory fume hood, feel free to opt for furniture made from chipboard.
