#M108 CAMSPEC M108 Visible spectrophotometer

This Programmable Visible spectrophotometer is a full QC instrument. Using a reconfigured grating monochromator from the successful M105, M106 and M107, the M108 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 keypad positioned next to the large, clear LCD display, allows the operator to rapidly switch between the %Transmission, Absorbance and Concentration modes and to set Zero.

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 (less than 0.001 Abs/Hour) and the low stray light (0.1%T @ 340nm).
The RS232 output provides a convenient link to a PC or serial printer for hardcopy. A low-cost application program which runs under WindowsTM includes the facility to create calibration curves. The reaction kinetics program, when used with the thermostatted cell holder accessory, provides an excellent low-cost enzyme analysis system.
This is the latest addition to our M100 Series of Visible Spectrophotometers. The replacement of the manual wavelength/filter control knob of the popular M107, by processor controlled stepper motors allows a step change in capabilities. The M108 has a 4 line x 20-character display and a 9-button keypad to allow easy use and full access to this intelligent spectrophotometer.

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 pathlengthflowcell 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 in the light beam. This means that the light beam is not bent and so remains aligned with the detector. This accessory is mounted on the same base-plate as the single cell holder.
Thermostatted cell holder and front panel, P/N 107-105. Accepts a standard rectangular 10mm pathlength macro or 4mm semi-micro cell. Requires connection to an external circulating water bath.
Standard Four-position manual cell changer, P/N 107-103. (Supplied with M108). Accepts four standard rectangular 10mm pathlength macro or 4mm semi-micro cells. The mechanical locating of the cell positions is very positive, giving excellent reproducibility.
Long pathlength Four-position manual cell changer, P/N 107-104. Accepts four standard rectangular 10-50mm pathlength macro cells.
M108 PC Application Software, P/N 108-110. For up to 3rd order concentration curves, timescans and wavelength scanning.
Printer, P/N 330-100. 40 character impact printer including battery charger, spare ribbon and spare paper roll.
