"Tubes"

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 Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

Demonstrate Bernoulli's principle.

For class model building.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

Fine hand instrument for qualitative visible spectrum analysis.

This bell jar demonstrates that sound waves can't travel and therefore can't be heard without air or matter.

Explore a full range of motion with the advanced hydraulic arm

100 feet of extra tubing for TeacherGeek projects.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

This demo features a cathode beam to explain the electromagnetic nature of electrons.

The Centripetal Force Kit is inexpensive and effective.

This vacuum plate and pad are the perfect tools for vacuum experiments.

This newly designed rheostat features a protective cover.

Students Investigate Alternative Energy Forms

Ideal for demonstrating that vapor pressure increases when temperature increases.
