Our Flame Photometers are used for measuring Lithium, Sodium, Potassium, Calcium and Barium. 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. The BWB Carbon Footprint is exceptionally low, in keeping with corporate objectives of being a responsible manufacturer.
