Laboratory ductless fume hoods are an important piece of laboratory equipment that is mainly used to protect laboratory personnel from the hazards of toxic and harmful chemical gases, dusts and aerosols. The following is a detailed introduction about the laboratory ductless fume hood:
I. Definition and Function
Laboratory ductless fume hood, also known as "clean gas type fume hood", is a semi-closed cabinet for in-situ treatment of laboratory exhaust gases through air filtration technology. It isolates the operator from the polluted air generated by the experiment through the directional flow of gas, effectively protecting the health of the experimenters.
Features
Ductless design: Ductless fume hoods do not require external piping, fans and make-up air systems, and the overall structure is simple and durable. This design reduces the workload of installation, maintenance and cleaning, and improves the working efficiency of the laboratory.
High-efficiency filtration device: Equipped with a high-efficiency filtration device, it can effectively remove microorganisms and particles in the air to ensure the cleanliness of the operation area and avoid contamination of experiments.
Airflow control and operating system: the ductless fume hood has sensitive airflow control and intelligent touch screen operating system. Users can adjust the wind speed and airflow direction according to specific needs to realize the best operating environment.
Third, the role
Protecting the safety of experimenters: isolating the operator from the polluted air through the directional flow of gas, effectively preventing the inhalation of toxic and harmful substances.
Prevent the leakage of harmful substances: isolate the operation area from the outside world and prevent the harmful substances generated in the experiment from leaking to other areas of the laboratory.
Provide a good operating environment: Provide superior working experience and light conditions to create a safe and comfortable working environment for the experimenter.
IV. Applications and Standards
Laboratory ductless clean-air type fume hoods are gradually being used in scientific research, medical and pharmaceutical fields. It complies with NFX 15 211:2009 standard, ASHRAE 110:1995 standard and JG/T385:2012 standard, aiming to protect the safety of laboratory personnel during experimental operations.
V. Technical details
Metal parts: Main material ≥1.2mm galvanized steel plate, epoxy resin electrostatic spraying, covered with durable anti-chemical lead-free coating.
Front and side panels: the main material ≥ 6mm acrylic board, good weather resistance and chemical resistance.
Real-time monitoring system: with real-time temperature and humidity environment monitoring system, fan monitoring and filter saturation alarm system and other functions.
High-efficiency filtration system: following the ASTM standard, effectively targeting acidic and organic gases, with a filtration efficiency of 99.995% for particles larger than 0.3um.
VI. Maintenance and upkeep
To ensure the normal service life and performance of the ductless fume hood, regular maintenance and upkeep is required. This includes checking the air inlet and outlet for dust accumulation, checking the performance of the equipment and fan, and regularly cleaning and replacing the filter.
To summarize, the laboratory ductless fume hood is an efficient and environmentally friendly laboratory equipment that provides a safe and comfortable working environment for experimentalists through its unique design and features.
