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.

Polarising Filter, 20 x 25cm
Polarising Filter, 20 x 25cmQuality filter that closes completely when placed 90 degrees above each other. (transmit below 0.005% with crossed filters).
Polarising filters, slides
Polarising filters, slidesAs 327000, but sold as a pair mounted in 50 x 50 mm slides without glass. 1 pair.
Polarising filters, unmounted
Polarising filters, unmountedUnmounted polarising filters for producing plane-polarised light. These quality filters block the light when positioned at 90 degrees to each other (transmitting only 0.005%).

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.
Potentiometer 100 Ohm on base
Potentiometer 100 Ohm on baseWire-wound power potentiometer (5 W). The potentiometer is mounted on a solid base with three 4 mm safety sockets. Excellent as variable load resistance, e.g. for smaller solar cells. Withstands up to 220 mA regardless of setting.
