When should the aerosol evacuation system on a flow cytometer be tested?

The aerosol evacuation system on a flow cytometer should be tested monthly to ensure optimal performance and safety. Regular testing is crucial because the aerosol evacuation system is responsible for removing potentially hazardous aerosols generated during sample analysis. These aerosols can contain infectious agents or other harmful substances, posing a risk to laboratory personnel.

By conducting these tests monthly, laboratories can verify that the system is functioning correctly and effectively mitigating the risk of aerosol exposure. This frequent testing aligns with best practices for maintaining workplace safety in environments where biological samples are handled. It also helps to ensure compliance with safety regulations and standards that mandate regular checks of engineering controls like the aerosol evacuation system. Regular maintenance and testing contribute to reliable operation and reduce the likelihood of equipment failure, thereby supporting accurate analytical results and the safety of the laboratory environment.
