10-100kΩ Single Dial Resistance Box Lab Supplies_Filtering Supplies this pipette-type hydrometer draws electrolyte

this pipette-type hydrometer draws electrolyte into a glass body with a colored-zone float for direct reading

providing dense uniform spheres for ramp-and-collision experiments where a heavier projectile is needed than the plastic marbles can provide

the high-microfarad decade for slow-RC-charging and energy-storage demonstrations

dimensioned to fit a pair of 75mm (3-inch) bar magnets and the keeper that bridges them while in storage

10-100kΩ Single Dial Resistance Box Lab Supplies_Filtering Supplies this pipette-type hydrometer draws electrolyteHigher impedance single decade resistance box stepping from 10k to 100k ohms in 10k ohm increments, providing the standard reference decade for op amp input and analog signal path circuit work.
