Enhancing Microbiology Precision through Airborne Contaminant Control in Sterile Environments
Microbiology research involves the study of sensitive samples, such as cell cultures, tissue samples, and microbial cultures, which require a sterile environment to prevent contamination. Contamination from external sources can introduce unintended microorganisms, skewing research data and undermining the validity of experiments.
A sterile environment with strict air quality control is crucial in microbiology laboratories. Airborne particles like dust, pollen, and microorganisms present a contamination risk. Air quality can vary depending on location and ventilation, with common air containing particles like mold spores, dust mites, and bacteria. In a lab setting, these contaminants can easily compromise sensitive microbiological samples and disrupt experimental integrity. Without filtration, airborne contaminants may easily enter laboratory environments and settle on surfaces, including experimental materials and equipment.
ULPA and HEPA Filter
Microbiology labs typically use specialized equipment to control and achieve required air cleanliness levels. A cleanroom or sterile facility provides a controlled environment where contaminants are minimized. Cleanrooms are equipped with special filters like ULPA (Ultra Low Particulate Air) or HEPA (High Efficiency Particulate Air) filters and follow stringent air quality protocols to maintain low particle levels.
This air filtration technology enables the cleanroom to maintain ISO standards for cleanliness, typically ISO Class 3 to 5, depending on the level of sterility required. Cleanrooms also incorporate airflow control systems that minimize particle movement. Laminar flow cabinets are essential parts of a sterile facility, creating work-area that support sample integrity by providing localized sterile airflow.

How Esco's Laminar Flow Cabinet Provide Sterile Work-zone
Horizontal Laminar Flow Cabinet provides a sterile work zone through a purified air that travels in a horizontal, unidirectional stream and leaves the main work chamber across the entire open front of the cabinet. |

Vertical Laminar Flow Cabinet provides sample protection as purified air travels across the working zone of the cabinet in a vertical, unidirectional stream and leaves the main work chamber across the entire open front of the cabinet. Most vertical laminar flow benches also have perforations at the back wall of the work zone which are designed to eliminate air turbulence and the possibility of dead air corners in the work zone. |
