Nuaire Class II

The Labgard 427 requires less exhaust air, more than 50% less air, than any other type of exhausted Class II biological safety cabinet, YET, by virtue of its series orientated HEPA filters, provides a total exhaust area in the rear one-half of the cabinet that can permit an increased, but judicious use, of flammable liquids as required as an adjunct to microbial studies.
