Introduction to scientific research products for fume hoods:

1. Structural combination: Adopting a three-stage combination cabinet, the upper cabinet (ventilation cabinet), middle (operation table), and lower cabinet (including a single-sided independent suction type composition cabinet and another side independent water, electricity, and pipeline system accommodating cabinet design).

2. Shell: Made by stamping steel plates with a thickness of 1.2mm or more, the surface is treated with acid and alkali resistant EPOXY powder paint coating.

3. Inner shell: Imported acid and alkali resistant fume hood lining is used specifically for fume hoods.

4. Tabletop: Made of laboratory specific ceramic plates (resistant to high temperatures of 1200 ℃) or made of 304 or 316L stainless steel. It has the advantages of corrosion resistance, antibacterial and anti-static properties.

5. Airflow board: A 6mm thick anti double special airflow board is used for the ventilation cabinet. The installation position and angle should ensure that the exhaust distribution is uniform and there are no dead corners. Under standard conditions, the exhaust volume ratio of the air outlets above, in the middle, and below the guide plate is about 50 ± 10% each to ensure that gases of different densities can be effectively discharged. In addition, it is designed with manually adjustable exhaust volume ratio to increase the exhaust volume ratio of the middle and lower air outlets to over 80% to meet the needs of different experiments.

6. Window: Made of 5mm thick tempered explosion-proof glass. Internally, a pituitary balance device is used, which can stay in any position up or down.

7. Height of upper and lower opening of cabinet operation door: 600-700mm.

8. Electrical accessories: universal socket (220V/10A), fluorescent lamp, fan on/off control.

9. Water supply: 1 set of DN25; Drainage: 1 set of DN50. (The configuration of water supply and drainage depends on user requirements)

10. Fan and air duct: made of glass fiber reinforced plastic, acid and alkali resistant, anti-aging. It is made of glass fiber reinforced plastic, acid and alkali resistant, and anti-aging.
