Just-in-time weighing for optimal precision and repeatability!

Claisse LeDoser-12 is a 12-position weighing instrument. It automatically weighs samples and dispenses borate flux with high precision so you get highly accurate XRF analytical results. Its three weighing modes (sample-to-flux ratio, catch weight and absolute weight) allow it to be seamlessly integrated in your laboratory procedures


  • Samples are ready just in time by eliminating the pre-weighing step and ensuring constant sample throughput, Le-Doser-12 instrument optimizes the synchronization of the sample preparation process and enables you to get your samples ready just in time for the subsequent fusion and analysis steps
  • Three different weighing modes: sample-to-flux ratio, catch weight and absolute weight
  • No need to precisely weigh the sample (can be scooped or roughly weighed)
  • No need to weigh all quantities of sample and flux in advance
  • Multilingual interface
