5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods this polished hardwood funnel stand

this polished hardwood funnel stand holds two 1

paired with electroscopes and pith balls in classic electrostatic-charging investigations

with identical volumes across specimens for direct mass-density comparison

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

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