IAC Industries' 5000 Series workbenches are designed specifically for cleanrooms and laboratories where it is critical to protect the integrity of the working environment to assure predictable results, and to protect against contamination. 5000 Series worksurfaces are fully sealed (class 100) and feature 1-3/16" solid core industrial grade particle board cores, finished in a choice of standard or ESD laminates. Worksurface support is provided by a sturdy 1" x 3" all-welded tubular frame designed and constructed to eliminate dust-collecting areas. Frame and legs are finished with cleanroom-approved powder coating for durable, chip-resistant service.
