Stalwart presents a wide range of quality equipment required in day to day function of a chemical lab to advanced instruments used for quality, assurance, control and research.
The SSA-Series AAS flame instruments provide ideal analysis solutions for laboratories requiring wide detection capability for over 60 elements and enable rapid, robust and reliable an analysis.The dedicated furnace atomizers of the Stalwart SSA-Series AAS employs PID controlled graphite furnace heating technology and Integrated Graphite Furnace Television, allows for unattended analysis of low concentration samples with accurate and repeatable results. The analysis is simplified by a wizard driven work-flow which guides the user through the process of method development, ensuring optimal parameters for a specific analysis.
