Specifications and standards
What does a colorimeter measure, and where does it fit against a spectrophotometer?
A colorimeter passes light through a coloured sample and measures how much is absorbed at a fixed wavelength, selected with an interchangeable filter — the basis for colourimetric assays such as protein estimation, glucose testing and water-quality parameters like turbidity and residual chlorine. A spectrophotometer does the same job but with a continuously variable, monochromator-selected wavelength across a much wider range, at a higher cost. Specify a colorimeter where your protocol calls for a small, fixed set of standard wavelengths (commonly across the 400–700 nm visible band); specify a spectrophotometer where the protocol calls for a wavelength scan or UV-range work below 400 nm.
Digital colorimeters give a direct absorbance or transmittance readout; analog (galvanometer-needle) models cost less but require the reading to be taken and converted by hand. Both formats are typically supplied with a standard cuvette or test-tube holder sized to the sample volume your protocol uses.

Frequently asked questions
What's the difference between a colorimeter and a spectrophotometer?
A colorimeter uses a fixed set of filter wavelengths, usually across the visible 400–700 nm band, and suits standard colourimetric assays. A spectrophotometer scans a continuously variable wavelength, including into the UV range, for a wider range of analytical methods at a higher cost.
Should I choose a digital or analog colorimeter?
A digital colorimeter gives a direct absorbance or transmittance readout, reducing reading error and speeding up repeat testing. An analog, needle-based model costs less but needs the reading taken and converted by hand.
What wavelengths does a school or college biochemistry lab typically need?
Most routine protein, glucose and water-quality assays fall in the visible range, so a filter set spanning roughly 400–700 nm covers the majority of undergraduate and diagnostic-training protocols; confirm the specific wavelengths your assay method calls for before ordering a filter set.
