"Gas Samplers"

Spectrum Tubes demonstrate the wave properties of different gases.

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

Investigate the spectral pattern of different gases.

This semi-quantitative spectroscope is a simple and economical alternative to expensive equipment.

This safe spectrum power supply features encased spectrum tubes.

These simple slide-mounted diffraction gratings are great for experiments with lasers and LEDs.
