In such conditions, appropriately selected laboratory equipment is the absolute foundation for protecting the health of all research personnel. The first and most important line of employee defense in this case is the laboratory exhaust system, commonly called a fume hood. It should be clearly emphasized that choosing the right device of this type is not just a matter of everyday operational convenience. Above all, it is a guarantee of meeting strict technical standards that genuinely build safety in the laboratory. - [How to Choose a Laboratory Fume Hood? 5 Parameters Worth Checking](https://www.renggli.pl/en/blog/how-to-choose-a-laboratory-fume-hood-5-parameters): (2026-08-21) A properly selected laboratory fume hood is the foundation of safe work with chemical substances. Find out which technical parameters to check before settling on a specific model. - [Why is proper fume hood ventilation so important?](https://www.renggli.pl/en/blog/laboratory-fume-hood-ventilation): (2026-08-18) A fume hood is the central point of almost every modern chemical, analytical, or biological laboratory. It is the place where most processes involving the risk of hazardous substance emissions are performed. - [Fume hood efficiency - how to calculate the proper airflow?](https://www.renggli.pl/en/blog/fume-hood-efficiency-how-to-calculate-airflow): (2026-08-11) Proper airflow in a laboratory fume hood determines the safety of working with chemicals. Effective extraction of fumes requires a precisely balanced exhaust system. Too weak of an exhaust does not protect the personnel, while too strong generates turbulence and energy losses. In this article, we explain how to calculate the volume flow and select parameters in accordance with health and safety standards. - [Fume Hood Maintenance and Inspections - How to Maintain Efficiency and Safety?](https://www.renggli.pl/en/blog/how-to-maintain-laboratory-fume-hood-step-by-step): (2026-08-10) Regular laboratory fume hood maintenance and timely technical inspections are the basic conditions for maintaining operational continuity and safety in any modern laboratory. A properly serviced laboratory exhaust hood effectively removes dangerous substances, protecting personnel from poisoning and ensuring a stable airflow velocity. Negligence in this area leads not only to mechanical failures but, above all, to the loss of protection guaranteed by certified laboratory furniture and integrated exhaust systems. - [Perchloric acid fume hood - special design requirements](https://www.renggli.pl/en/blog/laboratory-perchloric-acid-fume-hood-selection): (2026-08-06) Safe operation with concentrated perchloric acid requires the use of a specialized fume hood. The laboratory fume hood must feature a water wash-down system and guarantee a minimum airflow velocity of 0.5 m/s. - [Do all laboratory fume hoods provide the same level of safety? Key parameters worth paying attention to](https://www.renggli.pl/en/blog/do-all-laboratory-fume-hoods-provide-the-same-level-of-safety): (2026-07-31) Choch most fume cupboards on the market look similar, their effectiveness in protecting the operator varies drastically. An aesthetic casing can be misleading and does not reflect the precision of the systems responsible for retaining toxic gases. Real safety is determined solely by the internal airflow architecture and engineering details. When choosing a device, technical parameters should be analyzed rather than visual design. Full protection is guaranteed only by a workstation where modern laboratory furniture interacts closely with the ventilation system. The LabAirTec model by Renggli proves that the key to success lies in advanced airflow research and certified solutions. - [Laboratory fume hood - how to choose the right model for the type of research and applicable standards?](https://www.renggli.pl/en/blog/laboratory-fume-hood-how-to-choose): (2026-07-30) Choosing the right laboratory fume hood is one of the most important decisions when designing and equipping a modern research space. This device not only serves as a central point for protecting personnel from harmful vapors, but it is also crucial for maintaining the reproducibility of results and the purity of the analyses themselves. For a chemical fume hood to perform its task flawlessly, its specification must precisely match the profile of the research being conducted, the specifics of the reagents used, and the rigorous criteria of international safety standards. - [Laminar flow chamber - what is it, how does it work and where is it used?](https://www.renggli.pl/en/blog/laminar-flow-chamber-what-is-it-how-does-it-work-and-where-is-it-used): (2026-06-04) Laminar flow chamber is one of the basic equipment of modern laboratories, without which it is difficult to imagine work requiring sterile conditions. It enables safe procedures in which even the slightest contamination can disrupt the result, which is why it is used in many fields of science and industry. - [Laboratory extractor and fume hood - what is the difference and what to choose?](https://www.renggli.pl/en/blog/laboratory-extractor-and-fume-hood-what-is-the-difference): (2026-03-19) In the laboratory, not every ventilation system works the same - and choosing the wrong one can have a real impact on occupational safety. A laboratory extractor is a broad term that includes various solutions: from fume hoods, through hoods, to extraction arms. Each of them has a different use and level of protection. - [Fume hood in the school workshop - what to look for when choosing?](https://www.renggli.pl/en/blog/fume-hood-in-the-school-workshop-what-to-look-for-when-choosing): (2026-03-13) A safe school laboratory requires appropriate equipment, and one of the key elements is a fume hood. The right choice of model affects the comfort of work, the safety of students and the effectiveness of conducting chemical experiments. When buying, it is worth paying attention to the type of construction, the materials used and compliance with the standards, so that the extractor works well in everyday work in the school workshop. - [Why is laboratory ventilation crucial for staff safety?](https://www.renggli.pl/en/blog/why-ventilation-is-key): (2026-03-07) Laboratory ventilation is one of the most important safety systems in every chemical and biological laboratory. Its primary role is to protect the health and life of staff by effectively removing toxic vapors, flammable gases, aerosols, and bioaerosols generated during research and technological processes. Efficiently designed general mechanical ventilation prevents the accumulation of hazardous substances in the air, minimizing the risk of poisoning, explosions, and biological contamination. Equally important is the role of ventilation in creating a healthy work environment, which directly impacts staff concentration and comfort. - [What is a laboratory fume hood and what is it for?](https://www.renggli.pl/en/blog/what-is-a-laboratory-fume-hood): (2026-03-03) A fume hood (laboratory extractor) is a glazed cabinet equipped with a ventilation system, designed for safe work with chemical and biological substances in laboratory conditions. It is one of the most important protective devices used in chemical, analytical and industrial laboratories. A fume hood, also known as a fume hood or chemical extractor, is a key component of an occupational health and safety (OHS) system.
