Spectrophotometer/Spectrometer D3-1020.00, £399.00
 This Spectrophotometer/Spectrometer is ideally suited to many experiments across the sciences.
At the heart of the design is a modular system that consists of a base unit, cuvette attachment with a broad spectrum solid state light source and a fibre optic attachment with 1.2m fibre optic cable. The unit is powered using the supplied USB cable.
Connecting the Colorimeter
 Spectrometry is very straight forward with the easy to use software - connect the spectrometer, load the sample and with one click and the scan appears on screen. The software allows single or multiple traces (up to 10) can be shown.
Data can be collected as intensity, transmission and absorbance and if that is not enough there is the ability to create user calibrated scale.
A simple moving cursor bar shows the values for a wavelength, one simple click tells you the peak wavelength for each scan.
