Overview
Labtro Vertical Laminar Flow Cabinet LT-VLC204 draws ambient room air through the upper pre-filter, where larger airborne particles are removed before the air passes through the H14 HEPA filter. The HEPA-filtered air is then delivered vertically downward across the working area at an adjustable velocity of 0.3 to 0.5 m/s, creating a continuous clean-air zone over the sample and work surface. The 138 W centrifugal fan maintains stable airflow, while the control system allows fan-speed adjustment and monitors filter condition and operating status. The 304 stainless steel work zone provides a cleanable surface for contamination-sensitive procedures. After work is completed, the 253.7 nm UV germicidal lamp can be used for cabinet decontamination; its interlock with the front sash helps prevent UV operation when the sash is open.
