Spectrophotometers are typically used to measure light absorption but can also be used to measure reflectance. Infrared and UV spectrophotometers are used in a variety of scientific fields including physics, chemistry, biochemistry, and molecular biology. Spectrophotometers are historically larger instruments used in a lab setting, but there are now also a number of portable spectrophotometers on the market.

Spectrophotometer suppliers offer a number of options that allow your business to find a great deal, including:

1. Buy from a spectrophotometer supplier offering multiple models.
2. Use your new instruments in the field when you purchase portable spectrophotometers.
3. Save when you buy used spectrophotometers.

Compare instruments and spectrophotometer prices from a supplier selling a variety of models

If you don't have a specific manufacturer or spectrophotometer model in mind that you want to purchase, look for a supplier selling multiple instruments so you can easily compare your options.

I recommend: Hach is an industry leader in spectrophotometers, offering a range of spectrophotometers. View product overviews and technical specifications on their website, and find models useful in both the field and lab. Direct Industry offers a buyer's guide to photometers from multiple manufacturers. Find data on each profiled machine, and request a quote on the products that look right for your business.

Purchase portable UV spectrophotometers for use in the field

Measuring light is not just a task for the laboratory. When you're out in the field, you need spectrophotometers to complete your work. Spectrophotometer sellers offer products in a wide range of sizes. Larger machines may offer more functionality, but smaller models are also useful enough to get the job done when doing field work.

I recommend: Global Water Instrumentation sells the SPECTRO portable spectrophotometer. This model is great for use in harsh environments and is highly accurate in a wide range of wavelengths. For a spectrophotometer color meter, check out the portable spectrophotometer manufactured by Qualitest. Measure the spectrum of colors with a small and durable portable machine.

Browse through listings of used spectrophotometers for sale

If you're looking to save money on a spectrophotometer purchase, look into getting a used machine. You'll find fully functional equipment at a much lower price.

I recommend: CAE Online has one of the most comprehensive listings of used spectrophotometers on the Internet. See listings of technical details, prices and photos for many models, and submit a request for further information about each product for sale. GenTech Scientific sells both new and used spectrophotometers from a number of manufacturers.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  When buying expensive equipment like spectrophotometers, always look at warranty information before making a purchase. If you find comparable machines that you're interested in buying, compare warranties as well as price and specs so you know you'll be assured of a functional machine at least through the life of the warranty.
