CHEM4 Systems for Education

Unique Teaching Tool = More Data, Faster

Our CHEM4-series Spectrophotometers for Education are small-footprint, PC-based systems designed for professors, teachers and others who use spectroscopy as a teaching tool. These fully integrated systems -including spectrometer, light source and cuvette holder -are available at dramatic discounts with the trade-in of an old lab instrument. Acquire and display real-time complete spectral data (3648 wavelengths) in <1 second with our convenient, PC-based systems.

Sampling Optics: Direct-attach or Fiber

Each CHEM4 system comes with a fully integrated light source and cuvette holder that attaches to the spectrometer, either directly or via fiber, for a small-footprint system.

Direct Attach: The CHEM4-UV-VIS has a state-of-the-art, miniature RF-excited deuterium tungsten source. The CHEM4-VIS-NIR has a direct-attach combination tungsten and blue LED source. You can separate each spectrometer from its integrated light source to couple the spectrometer to any of our fiber optic accessories and light sources.

Instructional Materials for Teaching Labs

We've begun to develop a rich library of spectroscopy educational materials for both students and educators. Our first effort, Introduction to Spectroscopy in the Teaching Lab Using Ocean Optics Spectrometers, is a handy reference tool for introducing Ocean Optics to the modern teaching lab. Included are experiments and sample lab exercises for our spectrometer and PASCO Scientific's GLX Explorer dataloggers. Here's a sampling of featured exercises:

• Absorbance of Light vs. Concentration (Beer's Law)

• Kinetics of Crystal Violet Bleaching

• Spectrophotometric Determination of an Equilibrium Constant

• Spectrophotometric pH Determination Using Bromocresol Green

With so many lab exercises built around use of the old Spec20, these Ocean Optics spectrometer experiments -- all of which come from recipients of our educational grants -- are great for getting started in your new lab setup, or for use with any post-dispersive spectrometer.

Fiber: The CHEM4-UV-FIBER and CHEM4-VIS-FIBER include a light source and cuvette assembly that attaches to the spectrometer with an optical fiber. The advantage of this design is that the light source can be easily coupled to other fiber optic accessories such as reflection probes or transmission dip probes. The CHEM4-UV-FIBER uses a deuterium tungsten source and the CHEM4-VIS-FIBER comes with a tungsten source.

USB Interface for Easy Startup

All of our CHEM4 systems interface to a PC via USB. All

you need is to install the software and connect the included USB cable to your PC to be up and running. Wavelength calibration data are loaded automatically upon startup, and spectrometer power is supplied

through the USB.

Software for Linux, Macintosh & Windows

All CHEM4 systems come with student-friendly software, which includes functions for absorbance, transmission, relative irradiance and kinetics measurements. Our new SpectraSuite Spectroscopy Operating Software (pages 80-81) works in Linux, Macintosh and Windows operating systems.

Discount Pricing & Cost Sharing

Any learning institution qualifies for trade-in prices for CHEM4 systems. Save $1,500 by trading in your old monochromator or spectrometer. See the facing page for retail and trade-in prices. Our Innovations in Education Spectroscopy Grant Program rewards educators and
