5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Designed for parallel gravity filtration

Designed for parallel gravity filtration

with identical volumes across specimens for direct mass-density comparison

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

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

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

5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Designed for parallel gravity filtrationEqual 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.
