The
fundamental reliability of the instrument is assured by the absence
of motor drives.
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, Abs and Concentration modes, and to set Zero
Abs. The narrow 8nm 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 RS232 output provides
a convenient link to a digital printer for hardcopy or a PC. A low-cost
application program, which runs under Windows 9x includes the facility
to create calibration curves on screen.
