The BWB BIO Flame Photometer

The BWB BIO Flame Photometer

Purpose Built Flame Photometer with specialised software,
firmware and hardware

  • Specially configured for a range of user interests
  • “IRS” (internal reference standard) caesium or lithium option
  • single point calibration correction
  • internal reference standards
  • 5 and 6 point multi-ion calibration standards for urine and serum included
  • analysing li and ca along with na and k
  • operator independent determination of results
  • advanced automated determination of results
  • integrated printer with environmentally friendly ink
  • IQ, OQ, PQ web-based certification standard on bio and available on all bwb fes units
  • Correction of ca for the interference from high levels of NA
  • Technical Data
Sample rate 2 – 3.5ml/min
Tubing materials Silicone and Tygon®
Specificity Na/K/Li = <1% to each other when
equal in concentration at <100ppm
Required desk space for Instrument 50cm (H) x 45cm (W) x 45cm (D)*
For Safety reasons the Flame photometer requires 1m of unobstructed space above to allow dissipation of heat from the chimney.
