CO 7500 Colourwave Educational Colorimeter

• Designed with the student user in mind
• Rugged, portable and easy to use
• Extremely versatile
• Rechargeable battery version available

With the large, clear digital display and simple push button controls the CO 7500 is ideal for students in the laboratory environment. The unit is compact and robust enough to withstand the teaching environment and is available in AC power only or AC power with rechargeable NiMH battery. 

The CO 7500 is easy to use. The eight filters at 440, 470, 490, 520, 550, 580, 590, and 680nm are encased in an integral filter wheel. The wavelength required is selected by rotating this wheel until the relevant number is visible in the indicator window. The ergonomic design makes this very convenient and filters cannot be accidentally lost or damaged.

When used in kinetics mode to study rates of reaction the CO 7500 takes readings every second and these can be sent to a chart recorder via the analog output or results can be downloaded directly to a PC or data logging system. 

The samples may be measured in either standard 102mm pathlength cuvettes (a minimum of 400µl is required) or in 16mm diameter test tubes (adapters for 10/12mm test tubes are an optional accessory, order separately). There is a drain hole at the bottom of the cell compartment so that spillages do not affect the instrument.
