Benchtop fume hoods

Tabletop fume hoods – safe fume extractor

Tabletop fume hoods are compact devices designed to be mounted directly on worktops. Their main task is to ensure the highest level of protection of personnel through the effective discharge of hazardous substances. With their innovative design, these devices are the foundation of chemical safety in any modern laboratory, offering a number of advanced features:

• effective neutralization of toxic fumes, dust and gases,
• precise isolation of harmful substances by creating a vacuum inside the chamber,
• the use of efficient forced ventilation ensuring constant and controlled airflow,
• integrated decompression flap significantly increasing the safety of use,
• transparent walls guaranteeing excellent visibility and optimal illumination of the workstation,
• Solid housing that is an effective fire barrier.

The possibility of choosing from five width variants – ranging from 600 to 1800 mm – allows the equipment to be perfectly adapted to the specifics of a given research space. These systems are indispensable when conducting the most demanding tests, where rigorous emission monitoring and high ergonomics of operation are crucial.

Classic and non-extractor table fume hoods

The selection of the appropriate fume hood depends primarily on the specificity of the research work being carried out. Ecosafe models  operate in a closed circuit, using advanced HEPA and carbon filtration systems, which is confirmed by the strict NF X 15-211 standard.

This solution offers a number of key benefits:

• effective neutralization of dangerous organic vapours, corrosive substances, ammonia and formaldehyde,
• use of a quiet and efficient ECM fan,
• no need to connect to a fixed exhaust system,
• full mobility of equipment facilitating the reorganization of workplaces,
• no additional costs related to construction alterations.

Traditional table systems, on the other hand, operate on the basis of external ventilation, to which they discharge impurities through a dedicated connector. Such an arrangement requires a constant supply of fresh air to the interior, usually with the help of supply anemostats. Although both technologies guarantee the highest level of protection for personnel, the recirculating variants give much more freedom when arranging a modern and flexible laboratory space.

Materials – ceramic, polypropylene and steel

The robustness  of tabletop fume hoods is based on a durable structure made  of galvanized steel, which is additionally protected with epoxy paint. This solution guarantees full resistance to aggressive reagents and exceptional mechanical durability  of the entire device.

The key element of each workstation is the worktop, the material of which is selected in terms of the specifics of work in the laboratory. Among the options available are:

• solid ceramic sinters resistant to high temperatures,
• epoxy resin countertops,
• high-strength HPL boards,
• polypropylene designed to work with the most corrosive substances,
• Specialized finishes tailored to individual research needs.

The user's safety is ensured by a front glass made of ESG tempered glass or VSG laminated glass. The whole thing is set in a light but stable frame made of anodized aluminum. This non-flammable structure allows for years of trouble-free and intensive operation in the most demanding laboratory environment.

Compliance with PN-EN 14175 and flow monitoring

Tabletop fume hoods are professional laboratory solutions that rigorously comply with the PN-EN 14175 and DIN 12924 standards. Each device is CE certified, guaranteeing the highest level of personnel safety when working with chemicals.

The most important features and facilities of the system are:

• constant monitoring of air flow based on precise VOC sensors,
• active visual and audible alarms informing about any irregularities,
• advanced VAV system that adjusts the force of the extractor to the current position of the glass,
• smooth movement of the front glazing thanks to the use of solid counterweights,
• optional automatic window control for improved user experience,
• possibility of installing additional flow meters for full parameter control.

Thanks to their modern design, these devices not only facilitate daily control of tests, but above all significantly raise the standards of protection and ergonomics in any modern laboratory.

Chamber with hydraulic, gas and electrical systems

The well-thought-out design of the working chamber significantly facilitates the installation of the equipment, and the integrated media make it a fully functional workstation. The hydraulic system is based on acid-resistant fittings, a ceramic sink and a siphon, and also provides for the possibility of supplying demineralized water.

The most important technical and functional features of the device:

• safe electrical sockets installed outside the explosion hazard zone,
• precision valves for technical and flammable gases,
• energy-efficient LED lighting for excellent visibility,
• durable truss ensuring the stability of the mounted accessories,
• double structural walls for efficient vapor removal,
• functional technical openings facilitating the organization of additional connections.

The solid base equipped with leveling feet allows for optimal use of the space under the countertop. Laboratory cabinets, structures for distilleries or ventilated modules for chemicals can be freely placed there, which in practice significantly improves ergonomics and comfort of work in any laboratory.

Selection of table fume hoods for research processes

The choice of the right table fume hood depends primarily on the specifics of the research carried out and the type of reagents used. Professional extraction systems are used in many specialized areas, such as:

• monitoring of water and soil purity in environmental laboratories,
• precise analyses of heavy metals in geological surveys,
• testing food products with the highest hygiene standards,
• carrying out advanced reactions with the use of aggressive substances,
• eliminating the threat of toxic fumes in the education sector,
• ensuring repeatability of results in quality control departments.

The main task of the device is to protect personnel, which is why research departments rely on certified equipment of the highest class. The foundation of success is the well-thought-out design of the station – the use of a durable ceramic worktop significantly extends the life of the equipment, and efficient ventilation guarantees comfortable and stable working conditions. Each installation should be precisely tailored to the specific analytical challenges of a given laboratory.
