- Model BIO 943 - Flame Photometer



Purpose Built Flame Photometer with specialized software, firmware and hardware. The BWB BIO 943 is an offshoot of the popular BWB BIO. A simplified menu structure and enhanced Li detection make it a welcome addition to the BWB family. The ability to calibrate and measure Sodium, Potassium, and Lithium at the same time with the same dilution (from 1:6 to 1:100) streamlines throughput in many laboratories. We have retained the ability to enter and store two user-defined calibration curves should the user wish to readily measure differing sample types.

When connected to a PC with the BWB FP-PC app, the user can create .pdf files, .csv files, data presentations and reports that include all the key analysis data. The FP-PC Software also allows setup of the Automatic Fluid Handling System, AFHS, originally designed to work specifically with the BIO-943 unit.

The software enables you to view and edit the calibration curves. The intuitive user-friendly operation of the BWB BIO 943 spans all languages and appeals to all levels of users. The BWB BIO 943 is the must-have instrument in today’s research laboratory.

For sites that do not allow PCs or data acquisition in the test lab, the Printer provides the “hard copy” required for QA and QC purposes. The environmentally friendly print ink used by the printer has a minimum character capture life of 10 years. The printer is also compatible with other readily available paper stock.

To enhance accuracy and reproducibility there is an option to use either Caesium or Lithium as an Internal Reference System (IRS) that acts as an internal standard to adjust small changes during calibration and measuring.

  • 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 two separate calibration curves
  • Analysing li, 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 943and available on all BWB FES units
