Newport’s Scientific Grade Breadboard is identical in all ways to our Research Grade Breadboard, except that it is not equipped with constrained layer dampers. The SG Breadboard offers a 3/16 in. ferromagnetic steel surface, enhanced damping, sealed holes, steel honeycomb core, and optional microlocks. This means the SG Series still out-performs other manufacturers’ top-of-the-line breadboards.

Microlock™ Tiedowns

Microlock Tiedowns are the best way to precisely level your breadboard. Microlocks can be used to mount your breadboard on an optical table or directly onto any vertical or horizontal structure. see Breadboard Accessories and Options
