The flame test is an analytical technique often used for the identification of certain elements, primarily metal ions. The color of the flame is observed and the spectra of light emitted from the flame is viewed through a spectroscope.

Traditionally, this test poses safety concerns for students in a laboratory setting. This kit minimizes these concerns by utilizing small candles that are easier to manage in a lab setting. There is no loss in the clarity of the emission spectra from the candles, making it easy for students to observe and deduce what element is causing the colored flame. This kit contains enough material for 6 groups. Teacher's Manual and Student Study Guide copymasters are included.

Delivery information: Kit includes instructional manual and SDS booklet.

Caution: This product can expose you to chemicals including Methanol and Respirable crystalline silica, which are known to the State of California to cause cancer and reproductive harm. For more information go to http://www.P65Warnings.ca.gov.
