Designing research spaces for biomedical engineering is a task that requires combining several extremely different work environments. In a single room, living tissues, aggressive chemical reagents, and advanced electronics, sensors, and mechatronics come together.
A well-thought-out layout of furniture, ventilation, and installations is the absolute foundation on which a safe laboratory rests. Understanding the relationship between wet and dry processes is the key to creating an ergonomic and failure-free research environment.
Specifics and challenges in biomedical engineering laboratories
Biomedical engineering laboratories are much more difficult to optimally arrange than classic chemical or microbiological facilities. The main challenge here is the phenomenon of "intersecting" risks, which inherently require different precautions.
On one hand, researchers work with biological material, which generates the risk of sample contamination and requires the use of strict aseptic procedures. On the other hand, testing and integration of equipment take place in the same space.
These two worlds threaten each other. Moisture, chemical vapors, or accidental spills can irreversibly damage sensitive medical electronics. Conversely, working with a soldering iron, power tools, or power supplies near flammable or biological materials poses a direct fire and toxicological hazard.
For this reason, the flexibility of workstations and their smart separation become not so much an option as an absolute necessity. The space must allow for a seamless transition from cell cultures to the assembly of supporting devices, while minimizing the risk of any collisions between these processes.
Space zoning - division into "wet" and "dry" areas
The solution to the problem of intersecting risks is strict laboratory zoning. The basic principle is a clear separation of the work zone with biological and chemical material, called the "wet" or "dirty" zone, from the zone of assembly, programming, and testing of electronic equipment, referred to as the "dry" or "clean" zone.
Proper laboratory zoning requires planning logical communication routes. Employees moving with fluid samples cannot cross paths with engineers transporting sensitive measurement equipment. Space organization must enforce the safe flow of people and materials.
Modular furniture systems help achieve this goal, allowing for the physical but flexible separation of workspaces. The use of mobile island tables in the electronics zone enables quick reconfiguration of workstations for larger projects.
Worktops and the type of research performed
The selection of work surfaces must be strictly dependent on the purpose of a given research zone. The biological and chemical zone absolutely requires worktops resistant to strong disinfectants, acids, and bases.
Seamless materials, such as solid laboratory ceramics or epoxy resin, work best here, as they prevent the growth of microorganisms in crevices and are easy to decontaminate. In turn, worktops in the dry zone serve completely different functions.
Places where testing and assembly of medical equipment take place require antistatic (ESD) surfaces, which protect sensitive electronic components against discharges. Additionally, worktops in the engineering zone should feature increased mechanical resistance to scratches, impacts, and the pressure of heavy diagnostic equipment.
The role of fume hoods and ventilation in protecting personnel and electronics
A key element of infrastructure in biomedical engineering is the airflow management system. Vapors from aggressive chemical reagents, solvents, or strong biocides pose a threat not only to the researchers' respiratory systems.
The uncontrolled migration of vapors inside the room is one of the main causes of premature corrosion of precise electronic circuits, contacts, and sensors in testing equipment. Therefore, advanced laboratory fume hoods serve a dual protective function here.
Modern fume cupboards are equipped with intelligent variable air volume (VAV) control systems. They maintain a constant face velocity at the sash opening, regardless of its position. This ensures a maximum aerodynamic barrier.
Thanks to the effective hermetization of chemical processes inside the fume hood chamber, these systems not only protect the operator against exposure to pathogens and toxins but also effectively prevent the spread of corrosive agents to the "dry" zone, guaranteeing a longer lifespan for engineering equipment.
Power supply and utilities - ergonomic work with equipment
Complex biomedical equipment requires stable and diverse access to utilities. Engineering workstations must be supplied with electrical energy of appropriate parameters, as well as have access to the data transmission network and often technical gas connections (e.g., compressed air, nitrogen, or carbon dioxide).
The biggest challenge is routing cables and pipes in such a way that they do not cross the work area where liquids are handled. Traditional extension cords or countertop connections pose a direct risk of short circuits and electric shocks in the event of sample spills.
The optimal solution in this environment is to route the installations outside the work plane. The use of media ceilings, installation extensions, or special supply cells suspended above the tables radically changes the ergonomics of the workstation.
Suspending utility distribution frees up valuable workspace, giving engineers more room for prototypes. Most importantly, it physically separates electrical and gas connections from the zone exposed to chemical and biological fluid spills, maximizing work safety.
