Overview
Labtro Biological Safety Cabinet Class II A2 LT-BSC208 is designed to provide protection for the operator, samples, and surrounding environment during microbiological laboratory procedures. It operates with a 70% air recirculation and 30% exhaust airflow system and maintains an inflow velocity of 0.53 ± 0.025 m/s and downflow velocity of 0.33 ± 0.025 m/s. The cabinet incorporates two HEPA filters with 99.995% efficiency at 0.3 µm, along with filter-life monitoring and automatic airflow adjustment as filter resistance changes. Its work zone is constructed from 304 stainless steel, while the main cabinet body uses cold-rolled steel with an antibacterial powder coating.
