Holder for apertures, colour filters and the like.
The aperture holder is mounted on the Reuter lamp’s lens socket, can swivel and accepts apertures mounted in standard slides.
Determines the current through the sensor by measuring the voltage across the internal resistor.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
Set of four 4 oz bottles of mineral oil, for use with the Millikan Oil Drop Apparatus.
Set of plastic replacement coupons of varying strengths, designed for use with PASCO’s Stress/Strain Apparatus.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
