General Purpose Flame Photometer!


The BWB XP is the first and only 5 channel flame photometer

with simultaneous detection and display of all 5 elements.


The BWB XP was designed from the ground up, using new, innovative and modern technology to give unsurpassed levels of accuracy, usability and reliability while significantly reducing analysis time. Our 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. 


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


Our 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.
