Is there a specific requirement for the glass thickness of the laboratory fume hood?

The glass thickness of the laboratory fume hood does have certain specific requirements, which are usually to ensure the safety, durability and ease of experimental operation of the fume hood. The following are some specific requirements and considerations regarding the thickness of laboratory fume hood glass:

Glass thickness requirement

Standard thickness: The glass window of the laboratory fume hood is usually tempered glass, and its standard thickness is usually 5mm or 6mm. This thickness can provide good transparency and field of view, but also can withstand a certain impact force to prevent the glass from breaking and wounding.

Safety requirements: According to the EN14175 standard, the stroke above the safety height (500mm) cannot be electrically assisted, and manual upward lifting must be used. In addition, the single glass vertical moving door must have a braking function, and there is a special brake device to ensure the safety of the glass window during the moving process.

Consideration factor

Experimental content: The selection of glass thickness of the laboratory fume hood also needs to consider the experimental content. If high temperature, high pressure or corrosive substances are likely to be produced during the experiment, it may be necessary to choose thicker glass or glass with special materials to ensure safety.

Frequency of use: The frequency of use of the fume hood will also affect the choice of glass thickness. Hoods used with high frequency may require thicker glass to withstand frequent opening and closing operations.

Budget and space constraints: Laboratory budget and space constraints are also factors to consider when choosing glass thickness. Under the premise of ensuring safety, the appropriate glass thickness can be selected according to the actual situation.

Practical application

In practical applications, the glass Windows of most laboratory hoods meet the above thickness requirements. For example, some common laboratory fume hoods use 5mm or 6mm thick tempered glass Windows, which can provide a good operating view and ensure the safety of the experimental personnel.
