Filings encased in a plastic bubble, used to observe the effects of invisible magnetic fields. \n \nSpecification \nSize: 85mm dia.
Magnetic plastic marbles, 2 of each in 10 colours. Specification Size: 15mm dia.
Tin plate box with 130 mm sides. The vertical faces of the box are blackened, roughened, varnished and polished respectively. The top opening is 75 mm diameter and is fitted with a stopper. The apparatus is filled with water maintained at boiling
An apparatus for demonstrating thermal expansion, comprising of a captive brass ball secured to a mounted brass ring by a chain. Ring mounted rod with wooden handle. The ball passes through the ring when cold but will not pass through when heated.
For demonstrating that white light may be composed from all the spectral colours by rotation of the multi coloured disk. Comprising of a 200mm disc, and driven by gears with the help of driving wheel fitted with a handle can be clamped to a desk.
For ordinary magnets, iron bars, strips etc. Consists of a 250 mm long solenoid wound with insulated copper wire and mounted on a base, with switch and 4mm terminals. Operating voltage is 12 V A.C. or D.C. At 6A max.
For the rapid examination of spectral composition of white light, metal tube with draw out focusing and an adjustable slit fitted with a chromatic objective glass and 3 element prism. Complete in wooden box.
To be used with the Van de Graaff generator for demonstration various electrostatic experiments. It consists of 9 items: 1. Pointed wheel 2. Needle on a 4mm plug 3. Head of hair with 4mm plug. 4. Perspex pillar
These pigments normally have a pale, off-white appearance but in sunlight or UV light they instantly change to a bright, vivid colour. The pigments revert to their pale colour when away from sunlight or UV light. If the pigment is mixed with a bin

This liquid is non-toxic liquid paraffin containing a UV sensitive photochromic dye. Indoors it appears as a clear liquid but when exposed to natural light it immediately becomes coloured. This colour increases in intensity when exposed to direct
Building on the success of the SEP Energymeter, this new USB version boasts datalogging and an improved specification: Current range: ±7A (current can flow in either direction) Voltage range: ±25V
The SEP Wind Turbine is ready-assembled and can be used to carry out a wide range of experiments on wind power. The blades of the turbine can be easily attached, removed or adjusted, allowing students to investigate the effects of changing the num
A range of encapsulated solar cell modules mounted in sturdy black polycarbonate cases. The faceplate consists of tiny bubble magnifiers which maximise performance by enhancing light as it strikes the cell. Monocrystalline constructi
Non-RoHS Photoconductive cadmium sulphide cell with a spectral response similar to the human eye. As light falling on the cell increases, so the resistance of the cell decreases. Peak spectral response: Typ. 550 nm
