BSC Modification & Certification for University Laboratories
Restoring Critical Laboratory Equipment Through Advanced Technical Troubleshooting
A leading university research facility required specialist technical support after a significant number of Biological Safety Cabinets (BSCs) experienced persistent operational failures following PCB replacement and maintenance activities.
The cabinets had undergone multiple unsuccessful repair attempts over several site visits, resulting in prolonged equipment downtime impacting laboratory operations, research activity, and student practical work.
Aeris Flow was appointed to independently investigate the failures, identify the root cause, restore operational performance, and complete recertification of the affected cabinets.
Project Highlights

- • BSC certification
- • Technical troubleshooting
University Research Laboratories
Diagnosing Persistent Operational Failures
Observed issues included:
- Persistent alarms
- Incorrect operational behaviour
- Airflow instability
- Configuration failures
- Incompatible communication responses
The replacement control systems expected communication inputs and monitoring signals that were not available within the older cabinet chassis configuration.
"This incompatibility prevented correct cabinet operation and resulted in repeated unsuccessful commissioning attempts."
Initial investigations identified that the newly installed PCB systems were upgraded versions that were not fully compatible with the legacy cabinet infrastructure and existing sensor configurations.
Specialist PCB Reconfiguration & Technical Recovery
Aeris Flow carried out detailed fault-finding investigations combining manufacturer communication and system compatibility evaluation.
Reconfiguration success:
- Alarm conditions eliminated
- Operational behaviour stabilised
- Control systems functioned correctly
- Airflow parameters restored
- Monitoring systems accuracy verified
Through collaboration with the manufacturer, Aeris Flow identified the required configuration adjustments to enable compatibility between upgraded PCBs and legacy structures.
Specialist reconfiguration procedures were implemented across all affected units, restoring full functionality where previous attempts had failed.
Independent Performance Verification & Recertification
Once operational stability had been restored, each cabinet underwent a rigorous suite of performance tests to ensure full safety compliance.
All affected cabinets successfully passed certification requirements and were returned to operational service, restoring critical research functions.
Restoring Laboratory Operations & Long-Term Client Confidence
Through advanced technical troubleshooting and specialist system knowledge, Aeris Flow successfully restored multiple critical Biological Safety Cabinets that had remained unusable following prolonged unsuccessful repair attempts.
The successful recovery of the cabinets enabled the university laboratories to resume operational activities and restore critical research and teaching functions.
