Newton's Ring Apparatus with Metal Frame, 3" Capacity_100mL Open-frame demonstration DC motor exposing

Open-frame demonstration DC motor exposing armature

sized for whole-class visibility of momentum-and-energy conservation through pendulum collisions

sized for the next step up from the 100uA meter when small-signal circuits exceed its full-scale deflection

this polished hardwood funnel-and-burette stand adjusts height up to 18 inches for consolidated benchtop chemistry workflows

Newton's Ring Apparatus with Metal Frame, 3" Capacity_100mL Open-frame demonstration DC motor exposingUsed to produce concentric Newton's rings under monochromatic light, this 75mm metal framed apparatus demonstrates thin film interference and the wave nature of light.
