"tube coolers"

Relate Motion to Sound

A set of four borosilicate glass tubes of different shapes connected together to illustrate that liquids will stand at the same level.

Spectrum Tubes demonstrate the wave properties of different gases.

Simple, yet effective tool.

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

This safe spectrum power supply features encased spectrum tubes.

Provides an Optimum Seal Every Time.

Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

Safe alternative to Glass Titrators

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

Demonstrate the combining volume ratios of gases.

Demonstrate the power of a tornado in a bottle.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

100 feet of extra tubing for TeacherGeek projects.

Investigate the relationship between the speed of a fluid and its pressure
