Decade Capacitance Box, 10-100 pF, 63V Material_Polyethylene Flame stabilizer on this LPG

Flame stabilizer on this LPG Bunsen burner maintains a steady cone across drafts

Two borosilicate-glass flask electroscopes with discs

sized as a self-contained module that lights up when current flows the right way for polarity-and-circuit lessons

Continuously motor-driven to supply a steady high-voltage source

and d2sp3 atoms for hybridization-and-geometry visualization

Decade Capacitance Box, 10-100 pF, 63V Material_Polyethylene Flame stabilizer on this LPGDecade capacitance box stepping from 10pF to 100pF in 10pF increments at plus or minus 5% on a 63V rating, supplying the picofarad end of the cap reference series for RF tuning experiments.
