all-steel fume hood is one of the important local ventilation equipment in the laboratory. Its components can be mainly divided into ventilation upper cabinets, lower cabinets, countertops and accessories. Each component is important for its use. So how do we judge the quality of these components? The editor will give you a brief introduction below, I hope it will be helpful.  

 

       1, upper cabinet part  

      (1) The upper cabinet part needs to meet the specified safe wind speed standards during use, so that harmful gases generated during the experiment can be discharged in a timely and effective manner;    

      (2) The glass windows of the upper cabinets need to be explosion-proof glass to avoid damage to the glass and injury to the experimenters;  

      (3) The opening height of the upper cabinet must meet the customer's demand for operating space.

 

       2, countertop part

      (1) The all-steel ventilation cabinet top still adopts a butterfly-shaped design. In order to facilitate the cleaning of the experimental table, it can also effectively avoid chemical reagents during the experiment from leaking out of the ventilation cabinet and causing pollution;

      (2) The countertop material part needs to have chemical properties of acid and alkali resistance and corrosion resistance when selected. Secondly, it also needs to have specific high temperature resistance, load-bearing and other properties to facilitate the use of later experiments.

 

        3. Base cabinet part  

      (1) The base cabinet must be strong and stable. The material selection should be made with specific fire resistance, and it needs to have specific acid and alkali resistance and corrosion resistance, so that it can be used longer;

      (2) The power supply needs to be safe and reasonable, and it must be easy to repair water, electricity and gas.    

  

        4. Accessories  

      (1) All-steel fume hoods also need to consider some ancillary accessories, and the electrical system needs to consider explosion protection, durability and voltage;  

      (2) Water includes distilled water, pure water, reverse osmosis water, etc. The selection needs to be confirmed according to the specific use environment of the laboratory.
