The M107 High Specification Visible Spectrophotometer Using a reconfigured grating monochromator from the successful M105 and M106 models, the M107 offers more performance and versatility with only a modest price difference. The large sample compartment allows the use of a wide range of accessories, including a 4-position cell changer with holder for cell pathlengths up to 50mm. 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. Signal processing and results display are microprocessor controlled and the narrow 5nm bandpass gives improved analytical sensitivity. The outstanding optical performance is also indicated by the low zero drift (<0.001A/hr) and the low stray light (0.1%T @ 340nm). Wavelength selection is by rotary control. This simple mechanism automatically selects the order sorting filters, offers permanent wavelength calibration and eliminates wavelength initialisation routines at switch-on. The USB output provides a convenient link to a PC, the RS232 socket is for a digital printer. A low-cost application program which runs under Windows®, includes the facility to create calibration curves. The reaction kinetics program, when used with the thermostated cell holder accessory, provides an excellent low-cost enzyme analysis system.

The M107 High Specification Visible Spectrophotometer M107 / M108 Accessories The M107/M108 sample compartment (155 x 70 x 85mm) enables accessories to be exchanged in a few seconds. 10mm single cell or flowcell holder, P/N 107-102 Accepts standard rectangular and 4mm semi-micro 10mm pathlength cells, or a 10mm pathlength flowcell with Z=8.5mm. Test-tube holder, P/N 107-101 This V-type round test-tube holder holds tubes of diameters from 10 to 25mm. The access hole in the sample compartment lid means that any height test-tube can be used. The design of the holder ensures the tube is always central...
