The NPS SLT Signature Frame Science Lab Tables have "perfect chemistry" with any science classroom. These paragons of endurance are built with a choice of stylistic light oak woodgrain, or striking textured black legs beneath a "Chem-Res" tabletop with a MDF Core. The work surface is of solid black, firmly secured, high-pressure laminate, resistant to water and 13 commonly-used laboratory chemicals. Robust legs are 2 3/8" diameter, and adjust smoothly in 3/4" increments from 27"-42". Legs automatically lock at your height setting to conveniently accommodate all seating requirements. Easily assemble the SLT-AH thanks to pre-drilled pilot holes. Feet are outfitted with oversized glides, or optional casters. The SLT-AH meets MAS Certified Green environmental industrial standards. Optional Book Compartment models come with two storage compartments concealable with the included side-panel aprons.
