The universal hood, also known as the universal exhaust hood or universal air suction hood, is an essential safety device in laboratories. It is mainly used to quickly discharge small - scale dust, hot air, volatile gases, harmful gases, and other small - particle floating substances or gases generated during experiments or production processes.
FEATURE
Flexible Adjustment: The most significant feature of the universal hood is its high flexibility. The hood body can rotate 360°, and the air suction port can be adjusted at multiple angles. It can move freely within a certain radius centered on the fixed frame, and its height can also be freely adjusted. This allows for flexible adjustment of the angle and height of the hood according to experimental needs, adapting to experimental operations in different positions and directions.
Harmful Substance Capture: Through a unique air - suction port design, it can effectively capture harmful gases, smoke, dust, and other harmful substances generated during experiments. These substances are then guided through the connecting pipes to the exhaust system and quickly discharged from the laboratory, ensuring a clean and safe experimental environment and protecting the health of laboratory personnel.
Corrosion and High - temperature Resistance: The PP, PC, and other materials used for the hood body have excellent chemical stability, corrosion resistance, and heat resistance. They can maintain stable performance under extreme experimental conditions such as strong acids, strong alkalis, high temperatures, and high pressures, extend the service life, and adapt to various complex laboratory environments.
Easy Cleaning and Maintenance: With a simple structural design, it is easy to disassemble. The surface of its material is smooth and not easy to adhere to dirt, making cleaning and maintenance very convenient, reducing the management cost and maintenance workload of the laboratory
APPLICATION
Chemical Laboratories: Chemical experiments often involve various toxic and harmful chemicals. The universal hood can effectively capture the harmful gases and smoke generated by these substances. For example, during experiments such as acid - base neutralization reactions and organic synthesis, it can prevent the diffusion of harmful gases and protect the safety of laboratory personnel.
Biological Laboratories: In biological experiments, laboratory personnel often handle biologically active substances such as bacteria and viruses. The universal hood can effectively isolate the pollution generated by these substances and prevent harm to laboratory personnel. It plays an important role, for example, in processes such as cell culture and microbiological experiments.
Physical Laboratories: In some high - energy experiments in physical laboratories, radioactive substances or other harmful gases may be generated. The universal hood can effectively capture these substances, ensuring the safety of the experimental environment. It is applied in scenarios such as nuclear physics experiments and laser experiments.
PARAMETER
Joints: Usually made of high - density PP material, they can rotate 360° to adjust the direction, offering great flexibility. They can be positioned as required by users, and are easy to disassemble, recombine, and clean.
Joint Sealing Rings: High - density rubber that is not prone to aging is selected, ensuring the sealing and durability of the joints.
Joint Connecting Rods: Generally made of 304 stainless steel, they are sturdy and durable, connecting each joint to ensure the stability of the entire hood.
Joint Tightening Knobs: Made of high - density PP material, with embedded stainless - steel bearings, they lock with the joint connecting rods and can adjust the tightness of the joints to meet different usage requirements.
Airflow Control Valves: By manually adjusting the external valve knob, the air flow entering can be controlled, making it convenient to adjust the air extraction speed and intensity according to the actual situation.
Gas collecting Hoods: Mostly made of high - density PP/PC material, they have good corrosion resistance and transparency, and can effectively collect harmful gases and smoke.
Telescopic Ducts: Usually ∮75mm PVC/PP material, they have good flexibility and corrosion resistance, and can be telescoped as needed to adapt to different working heights and positions.
Fixed Bases: Made of high - density PVC material, injection - molded in one piece by mold, not bonded, with strong fastness and no risk of bottom detachment, ensuring the stable installation of the universal hood.
