Easily Used Student Visible Spectrophotometer M105 Our Model M105 is an easily used visible spectrophotometer, which is a robustly built instrument and gives a high level of performance. Wavelength is conveniently set using rotary control and the instrument is ready for use in just a few minutes. A membrane keyboard positioned next to the large, clear LCD display allows the operator to rapidly switch between %T and Absorbance. Also a bandpass of 20nm is well matched to the wavelength range of 335 to 1000nm. Remarkable stability and accuracy of the instrument is welcomed by all types of laboratories. A sample compartment accepts either standard 10mm rectangular cells, also known as cuvettes, or test-tubes. Special accessories are available for different diameter test tubes. The USB output provides a convenient link to a PC. A low-cost application program, which runs under Windows™, includes the facility to create calibration curves on screen and print out the results.
