The Bibby Scientific Model 6800 Spectrophotometer is built on a solid foundation of high quality sealed optics for optimum photometric performance. The user-friendly Flight Deck software ensures that operation of the Model 6800 is a simple and productive experience and gives access to the most comprehensive range of features and functions available at this level. The operating modes of the Model 6800 include:

Photometrics & Multi-Wavelength: Measure the absorbance or transmittance at one to six designated wavelengths or calculate the ratio and difference of two or three selected wavelengths using the dedicated 'Ratio Mode.' All results are displayed in a simple tabular format and an alphanumeric identity can be entered for each sample.

Spectrum Scanning: Scan in the range 190 to1100nm with resolutions up to 0.1nm and scan speeds up to 3600nm/sec. All data is displayed in both graphical and tabular formats with automatic peak and valley identification as well as manual selection. Post scan manipulations allow multiple overlays, spectrum calculations and derivative spectra to be displayed.

Time Scan & Kinetics: Measure the changes in absorbance or transmittance over 30 to 99999 seconds. The concentration or activity values are then calculated from the display by the free selection of a start and end time for which a regression curve is displayed and calculations made against an adjustable K factor.

Quantitation: Enables the accurate measurement of sample concentrations against calibration curves (K factor, 1st to 3rd order) based on up to twenty standards and up to three wavelengths for multi-component analysis. The easy recall of saved calibration curves leads to quicker, more accurate analysis.

DNA/RNA: Offers standard methods for measuring DNA, RNA or oligonucleotide concentrations using the absorbance values recorded at 260 and 280nm.

Protein Measurements: Offers pre-set methods for measuring protein concentrations using the Bradford, Lowry, BCA and Direct UV protocols. Any of the default settings can be modified allowing specific user variations to any of these standard test protocols.



The Bibby Scientific Flight Deck software also allows the easy import/export of results and methods ensuring that standard methods and procedures are carried out quickly and accurately, minimising the potential for user error. With a single click of the mouse the Model 6800 exports raw data and results to Excel for further processing or saving, maximising the time the unit can perform measurements.

The applications of the Bibby Scientific Model 6800 are extended further by the range of accessories. These include a water heated cell holder for temperature control from ambient to 40 degC, a micro cell holder for sample volumes down to 50uL and a variable path length cell holder for path lengths up to 100mm. Holders for glass filters and flexible films further compliment this range. All accessories can be easily fitted or changed by the operator by simply releasing a fixing screw.
