5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Simultaneous AC and DC output

Simultaneous AC and DC output on this low-voltage power supply

with adjustable slit and draw-out focusing for examining the spectral composition of light sources

sized for ripple tank and bulb-driven physics demonstrations

heating the bar until it no longer passes through the opening and contraction returns it

Half-size digestive system model fits smaller class benches while preserving the full esophagus-to-rectum path and accessory organ anatomy in two removable parts

5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Simultaneous AC and DC outputEqual mass density set in aluminum, brass, nylon, acrylic, and PVC, the shared mass isolating volume and density as the distinguishing variables across metals and polymers.
