The M105 Student Visible Spectrophotometer 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 Abs. The narrow 12nm bandpass is ideally 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 USB output provides a convenient link to a PC or a printer for a hardcopy. A low-cost application program, which runs under Windows 9x includes the facility to create calibration curves on screen. Display Light source Monochromator Digital L.C.D.
