Claisse LeDoser instrument has 3 different weighing modes:

  • Flux to sample ratio
  • Catch weight
  • Absolute weight

The fact that you can select the most appropriate mode ensures a seamless integration in laboratory standard operation procedure. Moreover, the tank stirrer option makes sure that LeDoser performance is constant for high and low throughput. It is also LIMS ready and the data transfer is simple and straightforward.

By letting this automated instrument work for you, you can get peace of mind and concentrate on more valuable tasks. The automated and constant weighing also eliminates calculation errors and fatigue for an increased accuracy and reproducibility. This instrument minimizes repetitive strain injuries (RSI) arising from weighing related tasks, hence improving the operators' safety.

Claisse LeDoser is equipped with industrial grade balance made from cutting-edge weighing system technology for unrivalled robustness.

Other Benefits of using LeDoser instrument:

  • Quick ROI
  • Low cost of ownership
  • Easy to use
