XP Plus Flame Photometer


Ready to use straight out of the box, enhanced purpose flame photometer.

The BWB XP PLUS was designed around the BWB-XP providing enhanced functions to give more utility while maintaining the unsurpassed levels of accuracy, usability and reliability while significantly reducing analysis time.

Customers do not need to waste valuable time changing filters and re-calibrating when a different measurement is required, as is a common requirement in all other Flame Photometer designs from 1951 to the present.

The BWB XP PLUS is the first and only 4 channel flame photometer with simultaneous detection and display of Sodium, Potassium, Lithium, and Calcium with 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.

With clean lines and contemporary bright colour schemes, the XP PLUS looks exceptionally modern and will fit into any laboratory. The instrument has a large LCD display, which can be viewed easily from a wide angle.

Metal casework provides a sturdy portable instrument and enables future recycling opportunities. ROHS compliant components and materials are used wherever possible.

The BWB Carbon Footprint is exceptionally low, in keeping with corporate objectives of being a responsible manufacturer.



Unlike other manufacturers who charge extra for vital accessories, BWB include everything required to use the product straight out of the box. Just add Gas! (Propane, LPG or butane).

We also provide as standard, data sharing via USB from the BWB XP to your PC. This ties the output of the BWB Flame Emission Spectrometer (FES) to the Internet or your company intranet systems and facilitates Distributed Control which is vital for Multi-National companies, Universities and various Governmental agencies.
