Spectrophotometer Product Information

We carry a wide range of spectrophotometers makes, including Agilent, Hewlett Packard, B & L, Spectronic, Perkin Elmer and more. UV, UV/Vis, DAD (diode array), NIR, Fluorescence, and RI (refractive index). These are just some of the types we carry. The Agilent 8452A is one of our most popular models. We can customize these spectrophotometers to meet your complete requirements. Don’t forget we “lease” sell and trade. We carry a huge parts stock as well.

Most of our sales are within the USA and Canada and in our local market of Toronto Ontario and the surrounding area (Mississauga, Etobicoke, Brampton, North York, Markham, Richmond Hill, Scarborough, Ajax, Pickering, Oshawa, Ottawa, Windsor, Guelph, Hamilton, Kitchener, Halton, London and Kingston.)

What is Spectrophotometry?

In physics, spectrophotometry is the quantitative study of electromagnetic spectra. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light, near-ultraviolet, and near-infrared. 

Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a Photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light. There are many kinds of spectrophotometers. Among the most important distinctions used to classify them are the wavelengths they work with, the measurement techniques they use, how they acquire a spectrum, and the sources of intensity variation they are designed to measure. Other important features of spectrophotometers include the spectral bandwidth and linear range.

Perhaps the most common application of spectrophotometers is the measurement of light absorption, but they can be designed to measure diffuse or specular reflectance. Strictly, even the emission half of a luminescence instrument is a kind of spectrophotometer.

There are two major classes of spectrophotometers; single beam and double beam. A double beam spectrophotometer measures the ratio of the light intensity on two different light paths, and a single beam spectrophotometer measures the absolute light intensity. Although ratio measurements are easier, and generally stabler, single beam instruments have advantages; for instance, they can have a larger dynamic range.

 

If you are a bargain hunter please give us a call, we always have instruments in stock, which have not been refurbished and can be sold as is in working condition.

Scientific Equipment Source provides service and training on site in most of central Ontario this includes neighboring cities Ajax, Whitby, Pickering, Oshawa, Toronto, Mississauga.
