The Wireless Spectrometer from PASCO is specifically designed for modern chemistry, biology, and physics labs. With Bluetooth and USB connectivity, students can quickly connect from their device or computer using the free PASCO Spectrometry Software. With this affordable spectrometer students can gather a full spectrum of data in under one second. After specifying a target wavelength, students can study concentrations (Beer's Law), rates of reactions, or investigate emission spectra using the optional fiber optic cable.

How It Works
Absorbance and Transmittance: Light from the LED-boosted tungsten light source passes through the solution and a high-quality diffraction grating. The CCD array detects the light and analyzes it. When used with the optional Fiber Optic Cable, the Wireless Spectrometer can perform emission spectroscopy experiments. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source to collect data.
Important Note: Solutions used within this spectrometer should be compatible with polystyrene (cuvette material) and ABS (spectrometer housing material). Use a glass cuvette or 12mm test tube for solutions with strong organic solvents like acetone, which will damage the plastic cuvettes.

Spectroscopy is the investigation and measurement of spectra produced by matter interacting with or emitting electromagnetic radiation. During a spectroscopy experiment, electromagnetic radiation of a specified wavelength range passes from a source through a sample containing compounds of interest, resulting in absorption or emission.
