Pacific Scientific 3313LL Met One Laser Airborne Particle Counter

The Pacific Scientific 3313LL Met One Particle Counter is a laser-based airborne particle counter designed for precise environmental and cleanroom monitoring. This instrument utilizes a photodetector to count particles by detecting light scatter as particles traverse a laser beam within the sampled air stream. Key technical features include:

This device is widely adopted in molecular biology and synthetic biology research settings, where stringent airborne particle control supports experimental reproducibility and compliance with regulatory standards. Calibration and maintenance considerations include routine checks of the laser, pump, optics, and replacement filters to maintain accuracy and reliability. The 3313LL is critical for airborne contamination monitoring in biotechnology, biomedical engineering, and clinical diagnostics applications where particle control influences the success of gene editing and bioprocessing workflows.
