Multi-Wire Spark Detector
Multi-Wire Spark DetectorThis apparatus gives a memorable and dramatic demonstration of the ionising properties of alpha particles. Alpha particles have short range but are very effective at ionising air.
Neodymium Wand pk5
Neodymium Wand pk5A set of 5 acrylic wands each fitted with a powerful 12mm diameter Neodymium button magnet. The wands make the magnets safe for pupil use.
Piezo Transducer
Piezo TransducerConsisting of a 15mm diameter ceramic element with integral, protective press-stud, the device gives voltage pulses of up to 20V when given a sharp tap. Demonstrate mechanical to electrical energy conversion with a voltmeter, data-logger or oscilloscope.
Potentiometer
PotentiometerA traditional wire potentiometer comprising 1m of 0.56mm diameter Constantan wire on a hardwood base. Connection is by 4mm sockets at either end with contact to the wire being made by a jockey at intermediate points.

Precision Variable Power SupplyTwo precision full specification power supplies for the school laboratory with unrivalled advantages in terms of design and electrical specification. See S100-906 for precision switched version.
QTC Test Rig
QTC Test RigThis Test Rig provides a simple but elegant system for studying the new Quantum Tunnelling Composite polymer, QTC.
RCCB Demo
RCCB DemoThis apparatus is a companion to the Circuit Breaker Demonstration LA10-170A
It shows all the working parts of a modern RCCB type fuse as used in domestic consumer units. The apparatus is contained within a robust plastic tray with protective acrylic cover and includes a clear circuit layout on the main panel.
Resistance Selector
Resistance SelectorMini substitution unit using a single rotary switch to select from twelve values all at 5% 0.5W.
Resistance Substitution Box
Resistance Substitution BoxA robust Resistance Substitution Box rated at 2W. Resistors are selected by means of 4mm sockets and can be arranged in series to give the full range from 1 to 12,221Ω.
Resistor Kit A
Resistor Kit APacks of 10 resistors covering the range 120Ω to 2.2MΩ, 5% tolerance together with 100 resistors 22kΩ on a bandolier.
Resistor Kit B
Resistor Kit BAlso for Advancing Physics Sensing Unit 110E. Five colour-sleeved resistors of values 300kΩ, 100kΩ, 75kΩ, 150kΩ and 100kΩ all at 5% tolerance.
Search Coil
Search CoilA 3300 turn, 25mm diameter coil on a plastic handle for investigating changing magnetic fields.
Splat The Rat
Splat The RatFun and dramatic demonstration of Lenz’s Law. Interactive and entertaining demonstration of induced currents and magnetic fields. Lenz’s Law can be demonstrated using the standard Eddy Current Tubes whereby a magnet falls through a copper tube at a slower rate than an un-magnetised weight.
Static Cell
Static CellWhen insulating materials rub together, electrons transfer from one to the other and, since the charge cannot be conducted away, the charge is retained on the surface.
Switched Power Supply
Switched Power SupplyA traditional switched power supply which uses established PSU technology to provide a smoothed power supply suitable for all laboratory applications which require a rugged source of emf at either AC or DC.
Three-phase generator set
Three-phase generator setThis kit serves as a model of an alternator. The kit consists of two parts, an induction unit with three coils and a round magnet, as well as a variable motor unit that rotates the round magnet.
Trans-Ratio
Trans-RatioTrans-Ratio is a fully self-contained transformer system which enables students to investigate turns ratios and efficiency with the minimum of complication.
