Vertical Laminar Flow Clean Bench LVCB-A13

Labtron’s Vertical Laminar Flow Clean Bench LVCB-A13 is a dedicated laboratory workstation designed to protect samples by directing HEPA filtered air in a smooth, unidirectional vertical downward flow. This airflow pattern creates an sterile environment over the work surface, effectively removing particulates and minimizing contamination. Unlike biosafety cabinets or fume hoods, it does not protect the user—its primary purpose is sample protection. Air is drawn through a pre-filter, then through a HEPA or ULPA filter at the top, and flows downward across the workspace before exiting at the front opening.

Labtron supplies advanced models of vertical laminar flow clean bench LHCV-A13.Airflow velocity in a vertical laminar flow bench is typically calibrated between 0.3 to 0.5?m/s ensuring consistent, unidirectional movement that minimizes turbulence and cross contamination. This controlled airflow washes clean air over the entire work zone uniformly and is critical for maintaining ISO Class?5 conditions. Speed is often adjustable via built in controllers and monitored via sensors or pressure gauges. Regular velocity testing is performed for certification and to verify performance over time.

In a vertical configuration, the HEPA or ULPA filter is mounted above the workspace and air flows downward, reducing contamination risk from operator’s hands and tools. Horizontal benches place the filter at the back, blowing clean air across the work surface toward the user. Vertical flow benches save benchtop depth and work well with tall equipment, while horizontal flow can offer slightly improved protection by ensuring operator-caused particles are pushed away. Each type offers unique benefits depending on lab design and application requirements.

Labtron’s Vertical laminar flow clean benches LVCB-A13 are typically equipped with HEPA filters or optional ULPA filters for more stringent applications. Ambient air passes through a washable pre-filter before reaching the high-efficiency HEPA/ULPA filter, prolonging filter life. These filters are crucial for achieving and maintaining ISO Class?5 cleanliness. Replacement schedules and efficiency monitoring are routinely required for certification and performance assurance.

Labtron’s vertical laminar flow clean benches LVCB-A13 are well-suited for tasks requiring a sterile environment such as electronics assembly, optical device preparation, PCR setup, tissue or plant culture, and mycology work (e.g. mushroom spore handling). They are favored where equipment is tall or bulky, or where downward airflow helps displace particulates more effectively. UV C lamps are often included to sterilize the interior before use, especially in PCR or biological sample prep. These benches meet laboratory cleanliness standards without needing a full cleanroom build-out.
