QTC Test Rig
QTC Test RigThis Test Rig provides a simple but elegant system for studying the new Quantum Tunnelling Composite polymer, QTC.
Ramp Surfaces
Ramp SurfacesExpand the investigative potential of the Lascells Ramp Set with this pack of five
interchangeable Ramp Surfaces. Featuring carpet, rubber, sandpaper, smooth
plastic (HIPS) and corrugated plastic, the set enables students to investigate how
different surface materials affect friction and the motion of objects on an inclined
plane. Ideal for teaching forces and motion, the surfaces encourage students to
collect, analyse and compare experimental data while exploring the relationship
between surface texture, friction and motion.
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.
Reaction Timer
Reaction TimerFor use with Lascells timers. The subject presses the START button and after a short random delay the light comes on. The subject has to press the button as quickly as they can in response. The timer records the interval between the light coming on and the button being pressed. No power supply required.
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.
