TWG renovated two laboratory areas at the dietary supplement giant’s vitamin/herbal supplement manufacturing facility. One project required relocating an existing Quality Control lab function within the plant; in another, the plant’s chemistry lab required renovation and the installing of a new NMR (nuclear magnetic resonance) machine with the customary accessory components. In this case, magnetic shielding was provided nominally at the machine enclosure, so shielded construction was not required at room level.
