The M108 Programmable Visible Spectrophotometer 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. Stepper motors for wavelength and filters Stores up to 200 methods/results Concentration calibration: up to 8 standards up to 3 replicates linear or linear through zero USB for PC control and RS232 serial output for printer Data output includes method number and name, wavelength, date and time, %T, Abs concentration, unit Selectable wavelength calibration and dark current measurement 325 - 1000nm wavelength range 5nm bandwidth Low stray light (0.1%T at 340nm) Large sample compartment (up to 50mm pathlength cells) Large selection of accessories Manual 4-cell changer, with a pair of 10mm glass cells included PC Application Software option for concentration curves, timescan & wavelength scanning Technical Specifications Display Light source Monochromator 4 lines x 20 character LCD Tungsten-Halogen 1200 lines/mm grating Detectors Wavelength Range Wavelength Accuracy Wavelength Resolution Wavelength Repeatability Noise Zero Drift Baseline Flatness Bandpass Stray Light Photometric Accuracy Photometric Range Printer Interface Computer Interface Power Requirements Dimensions Weight Silicon Photodiode 325 - 1000nm ± 2 nm ± 1 nm < 0.001A @ 500nm 0A < 0.003A per hour after warm-up 5 nm <0.1%T @ 340 nm +/- 1% 0-2 A -1 to 2.5A, 0-125%T and -9999C and +9999C RS 232 for printer USB for PC control 110/120V, 220/230V, 50/60 Hz, 60VA 420 x 330 x 180mm packed 645 x 535 x 370mm 7Kg packed 10Kg Spectronic Camspec Ltd Tudor House, Barley Hill Road, Garforth, Leeds, LS25 1DX, U.K. Tele: Fax: [email protected] www.spectronic.co.uk

The M108 Programmable 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/N107-101 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...
