In laboratories, air control is a central issue for safety, compliance, and performance. Whether for manipulations in analytical chemistry, microbiology, or the pharmaceutical industry, the use of an appropriate fume hood is essential to protect operators, capture vapors, limit contamination risks, and ensure a controlled work environment. The hood is thus integrated at the heart of the workstation, in the same way as laboratory benches, ventilation systems, or filtration devices.
However, purchasing new equipment often represents a significant investment, both financially and in terms of lead times. Faced with these constraints, more and more organizations are choosing pre-owned laboratory hoods, refurbished and tested to professional standards. This solution provides access to reliable equipment from leading brands while controlling costs and reducing environmental impact.
In this article, we discuss why a fume hood is an essential piece of laboratory equipment, the advantages of refurbished units, the different types of hoods available, and the essential criteria to consider before purchasing. The goal is to help you make an informed choice tailored to your applications and regulatory requirements.
Why is a fume hood an essential piece of laboratory equipment?
The laboratory hood plays an essential role in the safety of manipulations by protecting users against chemical fumes, suspended particles, or biological agents. It allows for the containment and extraction of hazardous vapors while preventing contamination of the workspace. Whether in chemistry, microbiology, or molecular biology, it contributes to controlling the quality of ambient air and preventing risks for both operators and samples.
Installed above the workbench, the hood creates a controlled laminar or turbulent airflow, depending on the model, to aspirate, filter, and exhaust pollutants. Some models incorporate activated carbon or HEPA filters for effective filtration of gases or fine particles. Choosing an appropriate hood therefore guarantees a secure atmosphere in compliance with current safety standards in sensitive environments.
The suction system, the general condition of the equipment, and its suitability for planned manipulations should be examined in particular. Choosing a refurbished pre-owned laboratory fume hood allows you to select professional equipment that has undergone verification before being put back into service.
Why choose a refurbished pre-owned laboratory hood?
Opting for a refurbished pre-owned laboratory hood is a relevant solution for organizations that want to equip themselves without committing to excessive investments. New equipment often represents a significant cost, whereas refurbished units provide access to proven professional devices restored according to strict procedures. This approach meets budgetary constraints while maintaining high requirements for safety and performance.
The refurbished hoods offered by Rewake are fully verified, cleaned, and tested to ensure proper operation. Critical elements such as the suction system, ventilation, and filtration devices are carefully checked. Choosing a refurbished hood means benefiting from reliable equipment that is available quickly and is part of a responsible laboratory equipment reuse process, without compromising on regulatory compliance or user protection.
What are the different types of hoods used in laboratories?
There are several categories of hoods, each adapted to specific uses depending on the types of manipulations performed and the level of protection sought. The laminar flow hood ensures a sterile, unidirectional atmosphere, ideal for cell cultures or microbiology work. It protects the product but does not protect the operator. Conversely, a filtration hood or ducted fume hood protects the user and the environment by capturing and filtering toxic vapors, aerosols, or particles generated during manipulations.
Microbiological safety cabinets (MSCs), for their part, offer triple protection: for the product, the operator, and the environment, thanks to a filtered airflow system combined with partial containment. The choice of hood type therefore depends on the laboratory's activity, the products handled (pathogens, solvents, volatile chemical compounds), and the standards in force. Rewake offers various refurbished solutions to meet every technical requirement for ventilation, suction, or containment.
Who is the purchase of a refurbished hood intended for?
Refurbished laboratory hoods are intended for a wide spectrum of professionals who need a reliable containment or filtration device. They are particularly sought after by public and private research centers, hospital laboratories, higher education institutions, as well as the chemical, pharmaceutical, food, and cosmetic industries.
These organizations regularly handle chemical, biological, or volatile products requiring secure air extraction or a controlled atmosphere above the workstation. In these contexts, integrating an appropriate hood is essential to meet safety standards, limit cross-contamination risks, and ensure a compliant work environment. By opting for a refurbished pre-owned hood, these actors can modernize their equipment while optimizing their budget.
How does Rewake guarantee the quality of its pre-owned laboratory hoods?
At Rewake, each pre-owned laboratory hood undergoes a strict refurbishment process designed to offer maximum safety to the end-user. Equipment is first completely disassembled, deep-cleaned, and then inspected in every detail. HEPA filters, activated carbon filters, or metal filters are systematically replaced if their condition does not allow for optimal filtration.
Tests include verifying airflow, noise level, proper fan operation, and compliance with current standards (NF EN, ISO, etc.). Each hood is returned to service with complete documentation including technical specifications, installation and maintenance advice, and a test report. Thanks to this rigorous protocol, Rewake guarantees safe, durable operation that meets the requirements of professional laboratories.
How to choose the right hood according to your applications?
The choice of a pre-owned laboratory hood must be based on several technical criteria directly related to the intended use. The first element to consider is the type of filtration required: particulate (HEPA), molecular (activated carbon), or both, depending on the substances handled (solvents, acid vapors, biological dust, etc.). The airflow rate expressed in m³/h, the face velocity, and the containment capacity are also decisive, especially for high-risk workstations.
It is also necessary to evaluate the compatibility of the materials (stainless steel, tempered glass, anti-corrosion components) with the chemical agents used. Finally, the dimensions, installation type (bench-top, wall-mounted, island), and compliance with standards (NF EN 14175, ISO 14644 for laminar flows) must guide the choice. Rewake assists each client in this selection process to ensure equipment is perfectly adapted to their actual conditions of use.
