Lascells
Mounted Potentiometer 470ohm
Mounted Potentiometer 470ohmA full range of variable resistors suitable for electronic investigations. 0.25W linear
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.
Newton Scales
Newton ScalesA set of bathroom scales calibrated in Newtons.
Max 1200N in 10N divisions.
Optics Bench Pair
Optics Bench PairThis is an economical alternative to a mounted optical bench. Each of the acrylic components can be easily aligned against a metre rule (not supplied) so that distances between components can be easily calculated and investigations into magnification and focal length can be carried out.
Optics Board
Optics Board9mm fibre board bonded to an MDF backing sheet for optics work. The fibre board takes optical pins for ray tracing etc.
Optics screen
Optics screenA 120 x 175mm white screen on a simple base for use in lens investigations where a real image is projected onto a screen.
Periscopes Kit
Periscopes KitA pack of 30 cardboard periscope nets with mirrors. Requires double sided tape for fixing the mirrors in place and normal tape for securing the net.
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.
Planck’s Constant
Planck’s ConstantThe system is an excellent illustration of modern electronics and gives a good investigation into a difficult topic in Post-16 physics.
Polarimeter
PolarimeterIntroduce students to the principles of polarised light, optical activity and polarimetry with this updated student Polarimeter. Ideal for supporting practical investigations at Physics and Chemistry A-level, the simplified design enables students to measure the optical rotation of optically active compounds in solution – e.g. sugar (sucrose) – while developing an understanding of polarisation and the interaction of light with matter.
Polaroid Analyser
Polaroid AnalyserThe Polaroid analyser gives a convenient method for analysing polarisation of light and stress in suitable materials.
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.
