This robustly built spectrophotometer combines a surprisingly high level of performance with a budget price. Wavelength is conveniently set using the rotary control and the instrument is ready for use within just a few minutes from switch-on. A membrane keyboard positioned next to the large, clear LCD display allows the operator to rapidly switch between %T and Absorbance and to set Zero Absorbance. The 12nm bandpass is well matched to the wavelength range of 335 to 1000nm.
The remarkable stability and accuracy of the instrument will be welcomed by quality control and teaching laboratories. The sample compartment accepts either standard 10mm rectangular cuvettes, including disposable semi-micro cuvettes, or test-tubes, and the analogue output provides a convenient link to a chart recorder.
An optional RS232 output is available to link the instrument to a printer or PC and a low-cost application program, which runs under Windows 9x includes the facility to create calibration curves on screen.
