AFMS that offer Validation and certification of Laminar flow clean benches in accordance with ISO14644:1 and manufacturers' requirements. These standards and guidelines play a crucial role in ensuring a sterile environment and protection of products.
Laminar flow clean benches are commonly used in laboratories, pharmaceutical facilities, and other environments where a sterile and particle-free workspace is essential. These benches use laminar airflow to create a clean and controlled environment, preventing the contamination of sensitive materials or experiments.
AFMS Testing of laminar flow clean benches involves various procedures to ensure their proper functioning and compliance with cleanliness standards.
Here are some aspects of testing offered by AFMS:
Aspects of testing offered
Airflow Velocity and Uniformity:
Measurement of the laminar airflow velocity and ensuring its uniform distribution across the work surface is crucial. Calibrated anemometers/ airflow meters and airflow visualization tools are used for this purpose.
HEPA Filter Integrity:
The High-Efficiency Particulate Air (HEPA) filters in clean benches need to be regularly tested to ensure they effectively capture particles. DOP test is employed to check for leaks or breaches in the filter. Calibrated photometers and aerosol generators are used for this purpose.
Airborne Particle Counting:
Regular monitoring of airborne particles within the clean bench is essential. Particle counters are used to measure the concentration of particles in the air and verify that it meets the specified cleanliness class.
Noise and Vibration Levels:
Some testing may involve assessing the noise and vibration levels produced by the clean bench to ensure they are within acceptable limits, especially in sensitive laboratory environments.
Visual inspections:
Lighting Inspection to ensure proper illumination. Vibration to ensure no excessive vibration on the unit
General Checks:
Inspections for any signs of wear and tear, loose connections, or malfunctioning components, including checking the condition of seals, airflow indicators, and control panels.
