There are several points about the differences between laboratory furniture atomic absorption hoods and universal hoods:
Atomic absorption hood:
1. Structure introduction: The complete set of equipment has a retractable stainless steel air hood and a manual adjustment stainless steel air duct.
2, stainless steel air duct: made of 1.0mm stainless steel, the diameter of the duct is DN200mm. There is a manual regulating valve on the air duct, the opening degree can be 0 to 180o, and the air volume can be adjusted arbitrarily.
3, stainless steel gas collecting hood: made of 1.0mm316 stainless steel plate, according to the experimental needs, the exhaust hood can be stretched up and down 150mm, to facilitate experimental operation.
Laboratory furniture universal exhaust hood:
1. Joint loosening knob: High-density PP material, flexible and freely movable;
2, the use of high-quality high-density PP material, with high mechanical strength, resistance to organic chemical reagent corrosion;
3. Cup-type gas collecting hood: PP with high transparency or pure transparent PC material, which can clearly see the experimental phenomenon when experimenting;
4. Joint sealing ring: It adopts EPDM material, which has the advantages of good sealing and aging.
5, telescopic duct: Φ75mm PVC material, the unique combination of the fixed frame can be rotated 360 degrees, with the fixed frame as the center, the movable radius can reach 1600mm, and there is a door closing button at the end of the gas collecting hood for airflow adjustment.
The original suction hood of laboratory furniture is the so-called exhaust hood, which has a large power;
The universal exhaust hood has a small power and is generally used in the gas phase.
Universal exhaust hood we use in liquid phase
In addition, due to the relatively large power of the original hood, stainless steel is usually used.
The amount of air exhausted is large, and the material is originally sucked to withstand high temperatures.
In order to reduce the noise, the universal exhaust hood is generally used, but the exhaust effect is not as good as the original hood.
It is ok to use the range hood as the exhaust air, but it is not safe. Because the motor of the oil smoke is not explosion-proof, when used in the laboratory or laboratory, many solvents are flammable and explosive, and it is easy to rotate due to the motor. I think it is not advisable to have a spark and a fire or an explosion.
