"tbe buffer"

This safe spectrum power supply features encased spectrum tubes.

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

Relate Motion to Sound

Study Wavelengths and Energy All With One Device

Used to investigate wavelength in air.

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

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

Spectrum Tubes demonstrate the wave properties of different gases.

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

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

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.

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.
