11-LED Array for Determining Planck's Constant Plastic Labware_Plastic Beakers & Jugs Hand-painted enlarged flower cross section

Hand-painted enlarged flower cross section exposes the calyx

and visceral organs in a combined lab-ready model

Two independent output channels on this compact AC/DC power supply deliver six selectable voltages up to 12V at 500 mA each

sized so a class can watch gas bubbles rise off each electrode in real time during electrolysis demos
