Spectrophotometers (UV-Vis, Fluorescence, Colorimeters)

Match the instrument's wavelength range and spectral bandwidth to your methods, as UV work needs coverage below the visible range. Narrower bandwidth gives better resolution for demanding measurements. Confirm these specifications with the seller against your requirement. Choosing the right optics ensures the instrument suits your assays.

Lamps are consumables with a limited life, so ask about lamp hours and whether a recent replacement was fitted. UV-Vis instruments typically use deuterium and tungsten lamps that age with use. Confirm whether spare lamps are available for the model. Lamp condition strongly affects measurement stability and running cost.

Confirm the sample compartment accepts the cuvette path lengths and formats you use, including any flow cells or micro-volume options. Some instruments include specialised holders for particular sample types. Ask whether any cell accessories come with the unit. Matching cell compatibility keeps the instrument ready for your samples.

Confirm whether the spectrophotometer runs standalone or needs PC software, and whether that software transfers. Ask which data output and storage options are available. Some instruments store methods and results onboard for convenience. Clear answers here help you plan how results will be captured.

You agree condition, price and delivery directly with the seller once the instrument suits your needs. On eligible listings, finance can spread a spectrophotometer's cost across a set term. Check the individual listing to see whether finance applies. Dealing with the owner keeps the process clear.
