• Single beam scanning
• 5nm bandwidth
• Multi-wavelength and kinetics analysis
• Wide range of sampling accessories
• Full interfacing capability
• Optional 8 position multi-cell changer (quantitation measurement)

The 6400 series incorporate a wide range of features designed to satisfy the needs of users seeking to maximise the efficiency of routine and specialised UV and visible spectroscopy tasks.
The Model 6400 Visible range unit operates at 320-1100nm.
The Model 6405 UV/Visible range unit operates at 190-1100nm.

Features include:

A customised LCD gives a clear readout of calibration data, sample data and all set-up options.

Simple keypad layout and operating protocols facilitates the setting of experimental parameters and initiating sample analysis procedures.

Multi-language capability allows screen instructions to be presented in a choice of English, French, German, Italian, Portuguese and Spanish.

Five operating ranges are available - photometrics, spectrum, kinetics, multi-wavelength and quantitation.
Full kinetics capability allows , usually in conjunction with the peltier cell block, full analysis of timed reactions

Calibration curves producing non-linear results can also be accommodated using in-built software and the multi-cell changer. Up to seven data points can be determined automatically and used to construct a calibration curve. A variety of statistical methods are available to ensure a close correlation to all curve shapes.

Full scanning capability allows scan range, speed and resolution to be user adjusted and the resultant scan to be auto scaled for enhanced visibility. Peaks and valleys are labelled with wavelength and absorbance values and can be readily down loaded to the optional internal printer, to a PC or a Centronics printer.

Sample presentation flexibility is a key feature, with cells from 100mm path length down to micro sample capacity being readily accommodated.

An integral printer module is available and can be supplied as a factory fitted item at the time of ordering the product or as a customer installable module.

Full interfacing capability using RS232 interfacing or an analogue output is provided as standard. Utilising the RS232 facility allows results to be down loaded via the front panel print key.
Both models incorporate a bi-directional interface allowing remote operation, calibration and interrogation by an external computer.

Traceable calibration standards provide the on-going assurance of accuracy required by Good Laboratory Practice (G.L.P.). A user set identification number (up to 6 digits in length) is entered and will be shown on any printouts produced by the instrument. In addition, each printout will show sample number, reading, unit of measurement, the wavelength analysis and the current time and date. Scans and concentration curves stored will also be time and date stamped. The 6400 series complies fully with EEC and US directives relating to ESD/EMC emission and susceptibility.
