This user-friendly power supply is ideal for powering transistor circuits and other electronic applications.

The durable Wilmshurst Machine is made for years of use.

Replacement hanger for slotted masses.

Demonstrate Characteristics of Primary and Secondary Cells

This box shows Planck's Constant in action.

The Ballistic Pendulum is spring-loaded for easy investigations.

Simple Yet Sensitive Instrument.

These laboratory burners are compact with a powerful and concentrated flame.

Two models provide detailed liver histology.

A detailed representation of nephron structure.

Lead students through the creation of their own pinhole camera with this basic construction kit.

Students use the St. Louis Demo Motor to research fundamental principles of electric motors and generators.

This power supply is earthed and tested for high-voltage insulation and leakage.

Teach magnetism, motion, Newton's Laws, and more with this fun ball launcher. Simply align these powerful neodymium magnets on a linear rail and arrange steel balls in a sequence for a truly engaging lesson.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

The Parallel Plate Capacitor helps students understand the principle of capacitance, its relationship with charge and voltage, its dependence on THE surface area of conductors, and the dielectric medium between two plates.
