Red-enhanced photomultiplier detector

  Wavelength range 190 - 850nm

  Calibration with up to 6 standards

  Method lock with password access

Where applications generate an Emission wavelength between 650 and 850nm, and the high sensitivity of a photomultiplier is still required, the model 6285 will fit the bill.

The measurement of Chlorophyll a, Algal Pigments and Rhodamine B are just three examples of where this enhanced wavelength range will be required, while all the general applications can still be carried out.

Like all models in the 62 Series the 6285 can display concentration values based on a calibration with one to six standards. A simple step-by-step procedure enables a calibration curve to be generated hence the accurate determination of sample concentrations over a wide range.

When working in the simple Raw Fluoresence mode the Auto-Set Gain function ensures the optimum reading resolution is achieved by measuring the fluorescence produced by the highest standard/ sample and automatically setting this to 95% of the full range.

On all of the models up to 20 methods can be created, then stored for future use. These methods can be locked so change or modification cannot be made without the entry of a security PIN code. To further conform to GLP an operator ID and calibration reminder can also be set. For temperature sensitive assays the optional electrically heated cuvette holder can be used.

628 501: - Model 6285 supplied with universal 12V power supply with UK, EU and US mains leads, pack 100 disposable cuvettes and operating instructions.
