How does a smartphone become a spectrophotometer? With the Carolina® Spectroscopy Chamber! The Carolina® Spectroscopy Chamber, like its traditional large-apparatus counterpart, allows light to pass through a sample in a clear, colorless tube. A smartphone app analyzes the light, and students convert the collected data to absorbance or transmittance to create calibration and measurement curves. With the durable, affordable Carolina® Spectroscopy Chamber, students can gain an understanding of how a spectrophotometer works before moving on to a delicate, more expensive instrument. Smartphone, light source, color analyzer app of your choice, sample tubes, and colored background are needed but not supplied. Works with Android® and iOS® devices Does not require special optical glass tubes Stays securely in place on nonslip feet FREE 1-year access to digital resources that support NGSS instruction included.
