The document compares two biosafety cabinet models, the Biobase BBC 86 and the Esco LA2-4A_, across several criteria such as ease of installation, ergonomic design, quality of construction, performance in tests, and cleanability. Overall, the Esco cabinet was found to have advantages in most criteria like requiring no removal of side panels for installation, having an easier to view and reach control panel, smoother surfaces and edges to aid cleanability, meeting or exceeding test standards, and a more robust filter sealing design. The Biobase cabinet had some issues like difficulty fitting through standard doors, sharp exposed edges, and failing some performance tests.
