The 6500 series are multi-capability scanning spectrophotometers designed to provide the user with a high quality system which offers all the features required by a scientist to manipulate and process spectral information.
The Model 6500 Visible range unit operates at 320-1100nm.
The Model 6505 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.

Graphical user interface (GUI) allows interactive control of all operating parameters. Both keypad and mouse operation are fully supported.

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. Up to twenty data points (standards), or up to seven when using the multi-cell changer, 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. A cursor facility allows the user to interrogate specific parts of the scanned data

A versatile sample compartment is fitted to the instrument to house the full range of accessories developed for the 6500 series.

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.

An automatic results log allows readings to be stored in a data file either when the print key is pressed; at a user defined set time interval or by a multiple sample assay using the 8 position cell holder. Data files have a user entered ID and can be saved in internal memory or to an external data card. Results saved in internal memory can be transferred to an external data card.

Method storage allows all user set parameters to be saved against a user identification. A method can be subsequently recalled which configures the instrument to the saved parameters. The instrument settings for a recalled method can be altered and subsequently saved against the same or a different method identification. Methods can be saved in internal memory or to an external memory card. Methods saved in internal memory can be transferred to an external data card. The instruments memory has the capacity to store a minimum of fifty methods.

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 20 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 6500 series complies fully with EEC and US directives relating to ESD/EMC emission and susceptibility.
