Laboratory fume hood installation equipment, the main thing is that the fume hood is installed as close as possible to the window, so that the pipe is easy to discharge to the outside, the shorter the pipe, the better the exhaust effect. Many people will habitually place the ventilation equipment in the corner of the wall. It is far from the experimental place. The province occupies other experimental furniture. Some important documents and important reagents should be placed near the test bench. Experiments can be started at any time. In fact, this idea is wrong. Regardless of the size of the ventilation equipment, it should be placed closest to the test bench.
Under normal circumstances, the ventilation device should be placed close to the test bench, because every time toxic gas or dust is generated from the test bench, it is the "hardest hit" that is polluted first and is seriously polluted. We must always take precautionary measures to prevent problems before they happen. Although the large ventilation equipment occupies a large area, the ventilation effect is also very good.
Ventilation equipment is different from other equipment used in the laboratory. Whether it is a faucet or a sterilizer, it can be used as long as you can take a few steps. At best, it is a little troublesome. However, if you put the ventilation device far away, when the toxic gas is discharged during the experiment, the ventilation device can not immediately convert and circulate the air, so even the best ventilation equipment will not have much effect.
Laboratory fume hood installation safety:
1. Adopting a single-slot exhaust structure to effectively discharge harmful gases.
2, streamlined handle, leaving a gap between the handle and the glass, because the flow of air on the table is rotated, the effective intake from the surface.
3, set the window anti-drop pin, in case the wire rope off the glass window accidentally falling, with the anti-drop pin will catch, to prevent people from hurting.
4, the glass window is made of tempered glass, even if the glass accidentally crashed or exploded, there will be no accidents.
5. Ventilation holes are provided in the upper part of the fume hood. Even if the glass window is closed, it can enter the air to avoid generating more negative pressure.
6, the fume hood shell is made of metal material, fireproof and non-combustible. The inner cavity is made of flame retardant or non-combustible materials such as anti-double plate and stainless steel plate. The countertop is made of solid core physical or chemical plate or stainless steel plate to prevent acid and alkali, heat and flame retardant.
7. The effective height of the glass window is 800mm, the inner cavity is 1200mm, and the height of the table is 800mm. It is ergonomic, easy to operate, and has a large space for safety.
8. The water nozzle and the air nozzle operate the handle remotely at the peripheral of the cabinet, which is more convenient and safer than direct manual operation.
