Where is the Laboratory Fume Hood normally installed in the laboratory?

Laboratory Fume Hood is a small device, the conventional size is 1500x850x2350, where should such a large device be installed? The most important thing is that the Laboratory Fume Hood should be installed as close to the window as possible, so that the pipeline can be easily discharged outdoors. The shorter the pipeline, the better the exhaust effect. Many people habitually place the ventilation equipment at the corners of the wall, far from the experimental place, and the province’s place of other experimental furniture. Some important documents and important reagents should be placed near the test bench. Experiments can be conducted at any time. In fact, this idea is wrong. Regardless of the amount of ventilation equipment, it should be placed in the closest place to the test rig.

Under normal circumstances, the ventilation device should be located closest to the test bench, because every time toxic gas or dust is produced is uploaded from the test bed, this is the first “polluted area” that is polluted and the most polluted. . We must always be prepared to take precautions against our predecessors. We must do all kinds of preventive measures at any time. Although large-scale ventilation equipment covers a large area, the ventilation effect is also very good.

Ventilation equipment is different from other equipment used in the laboratory. No matter if it is a faucet or a sterilizer, it can be used only a few steps away from it. At best, it is a little troublesome. However, if you ventilate the device far enough, when venting toxic gases during the experiment, the ventilation device will not be able to convert and circulate the air immediately. Even the best ventilation equipment will have little effect.

Conventional Laboratory Fume Hood height 2350mm, then the installation of the Laboratory Fume Hood laboratory level can not be less than the minimum height of 2900mm, Laboratory Fume Hood pipe is generally 250mm diameter or 200mm direct, of course, a little thicker pipe exhaust effect is still better, the noise is relatively Say it is low. When installing the Laboratory Fume Hood to open the exhaust hole, the conventional size is appropriate from the center point of the height of 2700mm, and the front-rear distance is about 450mm.
