Carolina ChemKits®: Smartphone Spectroscopy

(in stock)


Transform a smartphone into a spectrophotometer with the Carolina® Spectroscopy Chamber!

The Carolina® Spectroscopy Chamber, like its traditional counterpart, is designed to allow light to pass through a sample in a clear colorless tube. The smartphone application analyzes the light. Students then convert that collected data to absorbance or transmittance and create Beer-Lambert calibration curves to determine the concentration of food dye in popular powdered drink mixes.

Not only are students engaged in science using a device with which they are highly familiar, but they also learn how a spectrophotometer works on the inside before moving on to a delicate, more expensive instrument. Works with both Android™ and iOS® devices. Use the color analyzer app of your choice; no special optical glass tubes are required. Materials are sufficient for 30 students working in groups of 3.

Note: Materials needed but not supplied include smartphones, color analyzer applications, and glassware for serial dilutions.
