Accurately measure the velocity of your dynamics cart.

These rubber balls appear identical but differ in elasticity to demonstrate energy conversion.​

This newly designed rheostat features a protective cover.

This nickel coated plate uses a rubber pad to achieve air tight contact with a bell jar. It features a stopcock and center hole with safety screw plug and a rubber gasket.

3' Fiber optic element, easily demonstrates the bending of light through the fiber optic wire. An inexpensive way to introduce students to fiber optics specifically the use of fiber optics for visual applications.

Used to open and close an electrical circuit momentarily, it is also excellent for demonstrating Morse code.

A high quality PVC coated copper wire. AWG 18.

A set of dynamic cart trolleys are used for investigation on momentum, velocity and acceleration. Each trolley consists of two rectangular wooden blocks, 300 mm long, moving on three low friction wheels (ball bearings in wheels). The trolley is fitted with spring loaded impulse rod. It has a provision for stacking the trolleys on top of each other with removable pins. It is supplied with two rubber corks and 2 needles, so trolleys may be stuck together for inelastic collisions. A striking pin for releasing the striker and 3 pins or dowels for stacking are provided. One trolley weight approximately 1 kg.

The Resistance Substitution Apparatus is convenient for general-purpose resistance work.

The High Speed Gear Box, High Efficiency, is perfect for high speed applications

Both of these sets come with a roll-up style canvas storage pouch and a solid rubber activator.

The Quantitative Centripetal Force Apparatus' simple concept and robust construction guarantee reliable lab success.

Classroom Package of Large Needles

All Types and Sizes for all Optical Applications.

The durable acrylic pump plate accommodates bell jars up to 9" Ø.

Soft iron is a classic example of a readily magnetized material.
