LI Flame Photometer


The most accurate lithium flame photometer ever manufactured

BWB Flame Photometers have always been renowned for a highly stable and accurate lithium measurement.

This winning formula has been developed further with specific adaptation and optimisation of the proprietary BWB optical array detection systems.

A well earned thank you to Dr. Richard Roman of the University of Mississippi for his invaluable assistance on this Lithium specific FES.

The BWB Li uses multiple lithium detection channels. This latest configuration has been exclusively designed to specifications laid
out through consultation with our customers.

The BWB Li is the first of it’s kind. Engineered with a single purpose,
the BWB Li is the most accurate and advanced lithium flame photometer
(FES) ever manufactured.
