Jumbo-Sized Pulleys are Designed for Classroom Demonstrations

This set includes 0.5, 1, 2, 3 and 5 N springs.

Complete optical bench kit for exploring image formation and lens behavior in physics labs.

Simple and Inexpensive

Useful for exploring the build-up of static electricity in physical science classrooms.

Use the two sets of symmetrical round jaws for simultaneously holding two round objects, each up to 35 mm in diameter. Each of the rubber-coated clamps rotates 360° and may be locked at any angle. The unit attaches to any standard support rod up to 13 mm in diameter.

An interesting and unique kit designed for hands-on exploration of electrochemical principles.

A very simple and visual demonstration of the level of conductivity of almost any solution.

This set is made from high-quality borosilicate glass and all joints are ground 19/22.

Durable and corrosion-resistant.

An alternative to a ballistic pendulum designed to demonstrate the conservation of momentum.

Double convex lens for optics experiments.

No two liquids have exactly the same boiling point. Therefore it is possible to separate any mixture of two liquids by raising the temperature of the mixture to a point where one of the liquids will boil but the other will remain liquid.

Compact Daniell cell kit with nested-container design for efficient electrochemical experiments.

This apparatus facilitates the calculation of gravitational acceleration through free-fall experiments.

Set of three metal rods with 1 cm engravings for demonstrating Archimedes' principle and buoyancy.
