Each element emits a specific wavelength of light, thus a characteristic color, when excited by a flame. This unique flame test kit produces better results and is easier to perform than the expensive platinum wire procedure. A laboratory burner is pl...

Bananas are a good source of potassium—but do they also contain sodium? This flame test demonstration provides a safe, unique method for observing flame test colors of metal ions—no flammable solvents required! Demonstrate the characteristic colors p...

A radially polarized filter is placed on an overhead projector stage and a regular (parallel) polarized filter is positioned above it. As expected, the image produced shows four quadrants, alternating light-dark-light-dark. As an optically active sol...

Demonstrate the characteristic colors of several metal ions with a flame test that is large enough for an entire classroom to observe. An easy setup and excellent flame colors make this kit a perfect addition to your chemistry demonstrations. Add a f...

Diffraction grating film (holographic type). A diffraction grating is a plane surface which contains literally tens of thousands of microscopic lines or grooves. A phenomenon called “diffraction” causes white light to be split or diffracted into its ...

Wow!! That's what students will say when they see the colors of the spectrum using the Flinn C-Spectra™. The vivid spectrum with distinct color separations helps students understand and enjoy the spectrum. The best feature of all is that you'll no lo...

Chemistry teachers-now you can have your own low-cost video camera to show chemical demonstrations, experiments and close-ups of exciting chemistry phenomena. How many times have you shown students a demonstration only to wish you could “macrosize it...
