Resistance Substitution Board 33 Ohms - 10M Ohms, Extremely Useful For All Circuit Applications. Great For Electronics Classrooms Or Labs, Or For Use In Circuits Under Design Or In Testing Conditions, Board Dimensions Are 5 X 3.5 X 2 Inches.
Racing Rings consists of three rods one each of copper, aluminum and PVC, Ring magnet is dropped down the PVC rod, it falls unobstructed, Two metal rods create an induced magnetic field to that adds resistance to the rings travel, metals are different, they fall at different rates
Resonance Tube Apparatus, Long version, Material: Acrylic, Mounted on retort stand with clamp and boss, with metal vessel, connecting tubing and spring clip supported on iron ring, Dimension: 120cm
Physical Characteristics of Gases kit, 15 Gas Demonstration Hardware, Gas laws (Boyle’s, Charles’s and Gay-Lussc’s) are simple mathematical relationships between volume, temperature and pressure.
Acids and bases, Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic.
Hareft s Apparatus, Mounted on a wooden stand with a scale, comprises a three-limbed glass tube with rubber tubing on the centre. For comparing the densities of liquids by measuring the height of two columns of liquid produced by applying suction, Dimensions 68 x 30 x 15 cm
Boyle's law Horizontal apparatus, A horizontally mounted acrylic tube having a graduated scale (0-300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap.
