Hoffman Voltameter with Glass Stopcocks, Borosilicate Glass Neulog sized for the longer reach

sized for the longer reach when students wire across a bench between power supply

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

and triangle waveforms from 0 to 2 kHz

sized to read one step up from the 0-1A meter when student circuits draw past the lower meter's full-scale deflection

accepting solar-cell input or battery power for energy-conversion student demonstrations

Hoffman Voltameter with Glass Stopcocks, Borosilicate Glass Neulog sized for the longer reachBorosilicate glass Hoffman electrolysis apparatus with two 50mL graduated outer tubes, a 200mL central bulb, glass stopcocks, and both platinum and carbon electrode sets.
