PFP7 & PFP7/C Flame Photometers

Flame photometer

Summary

Models PFP7 and PFP7/C are low temperature, single channel Flame Photometers, designed for the routine determinations of Sodium (Na), and Potassium (K). Additional filters are available for the measurement of Lithium (Li), Barium (Ba) and Calcium (Ca). Both instruments are fitted with automatic flame failure detection for user safety, making them ideal for use in clinical, industrial and educational applications.

Features

  • Na & K Filters as standard
  • Ca, Ba and Li Filters as optional accessories
  • Electronic Flame Failure
  • Fine and Coarse Sensitivity Controls
  • Operates on Propane, Butane, Natural Gas or L.P.G. supplies
  • Recorder Output
  • Easily Maintained
  • Economically Priced

Product Details

The Models PFP7 and PFP7/C are low temperature, single channel Flame Photometers, designed for the routine determinations of Sodium (Na) and Potassium (K). Additional filters are available for the measurement of Lithium (Li), Barium (Ba) and Calcium (Ca). Both instruments are fitted with automatic flame failure detection for user safety, making them ideal for use in clinical, industrial and educational applications.

The Model PFP7/C is designed specifically for use in Clinical applications. The in-built lineariser circuitry enables readings of both Sodium and Potassium, at the normal clinical serum concentrations, to be directly displayed in mmol/l. Serum samples need to be diluted 200:1 or 100:1 prior to presentation to the flame photometer. To enable this to be carried out efficiently Burkard Scientific are able to offer the Model 8225 Dilutor.
