Glass equilibrium tubes with plastic base demonstrate pressure equilibrium

Fine-gauge 24 SWG bare copper wire on a 250g reel approximating 375 feet

allowing this tangent galvanometer to convert deflection angle into an absolute current reading

and magnetic strength relationships

gripping square or round rods up to 16 mm and accommodating flat articles like rulers and drawing boards

Eureka/Constantan Bare Wire, Model J Plastic Labware_Plastic Funnels Glass equilibrium tubes with plasticUsed to construct resistance coils and thermocouple legs that don't drift with temperature, this bare Eureka constantan wire takes advantage of the alloy's low temperature coefficient.
