Salt Bridge, inverted U tube with its ends closed by sintered discs. Length (in)7.5 x Width (in)5.5 x Height (in)1.2, provides a more effective method of making reversible cells then wet filter paper/agar gel methods. Diameter of arms 13 mm, overall width 80 mm, overall height 100 mm
Free Fall Apparatus Economy, for determination of the gravitational constant ft gft, This kit has a wooden base, 1.1m rod and a movable electro magnet, can be moved anywhere on the rod, when the ball is released the timer is triggered and stopped one the ball his landed on the base
Millisecond Counter Apparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate.
Determining the gravitational constant, with the gravitation torsion balance after Cavendish- Measuring the excursion with a light pointer, Required but not included: Laser light pointer
