The effects of contamination
Contamination poses a significant risk to technical processes, experiments or production activities, as well as to the individuals involved. Unguarded proliferation of contamination can quickly lead to product damage, yield reduction, product recalls and other outcomes highly detrimental to business. Products in a range of industries are recalled due to ineffective contamination control systems.
Cleanroom High Efficiency Particulate Air
High efficiency particulate air (HEPA), originally called high-efficiency particulate absorber but also sometimes called high-efficiency particulate arresting or high-efficiency particulate arrestance, is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE).
Cleanroom HEPA filters specifications
HEPA filters, as defined by the United States Department of Energy (DOE) standard adopted by most American industries, remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. The filter's minimal resistance to airflow, or pressure drop, is usually specified around 300 pascals (0.044 psi) at its nominal flow rate.
Contemporary Cleanroom suit technology
For a little over a century, emphasis on performing industrial and medical work in germ and contaminant free environments has risen dramatically following advances in our understanding of these contaminants’ effects. Additionally, as improvements in the sophistication and delicacy of components used in computers and other complex products progresses, the need to keep them contaminant free grows. As such, the development of cleanrooms has been as important to scientific research as it has been to the manufacturing of technology resulting from this research.
The costs of building a cleanroom
For those of us in lab design, we know that cleanrooms can be one of the most complex spaces to design. Cleanrooms provide a space where the particulate count in the air is regulated. A wide variety of clients require clean spaces to conduct their business, whether it’s based on their own SOPs (standard operating procedures) or required by regulatory agencies. Cleanrooms offer an indoor environment unique to any other indoor environment—and with it, pose some unique design challenges.
Pass-Through Desiccator Chambers
Low-humidity storage of sensitive samples and supplies can now be done in a pass-through chamber. Desiccators in plastic or stainless steel to comply with ISO cleanliness requirements.
