Wireless Spectrometer - PS-2600



The PASCO Wireless Spectrometer is specifically designed for introductory spectroscopy experiments. The Bluetooth and USB connectivity enable use with tablets and computers. With this one apparatus, you can measure intensity, absorbance, transmittance and fluorescence, making this a powerful and intuitive tool for your spectroscopy needs. Includes 10 plastic cuvettes and lids.

PASCO's FREE Spectrometry Software (download link below) walks you through the process of calibration, performing a full spectrum scan, determining the optimum wavelength for study, and concentration and kinetics experiments. 

Replace your Spec20!

With the release of version 2.0, the Spectrometery software now allows for direct wave length entry and real-time digital readout giving it the same functionality as a Spectronic 20 while providing lots of additional features and functionality as well.

And the software application is available for PC®, Mac® and iPads® which makes the PASCO Spectrometer easy to use in any technology setting. Also, select Chromebooks can now use Spectrometry as well. See below for details.


The Wireless Spectrometer was fully reviewed in the NSTA blog on September 30th, 2015.

"Amazing enough on its own, but in true paradigm shifting fashion the PASCO Wireless Spectrometer presents the invisible world of visible light in the magical cartoon chart we’ve seen only in static textbooks for most of our lives. It's as if the dinosaur skeletons in dusty museums suddenly came alive and reacted to the world."

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 for collection and analysis.

The optional Fiber Optic Cable allows you to perform emissions spectroscopy experiments with the PASCO spectrometer. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source.

Important Note: Solutions used within this spectrometer should be compatible with polystyrene (cuvette material) and ABS (spectrometer housing material). In particular, strong organic solvents such as acetone will damage the cuvettes.
