Overview

LeDoser, a Claisse technology, is an automatic weigher specifically designed to weigh and dispense borate flux with high precision. 

It is more than a weighing device: it is an essential instrument to achieve constant, on-target results and efficient laboratory management.

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

Weighing modes

LeDoser has 3 different weighing modes:

  • Sample-to-flux ratio
  • Catch weight
  • Absolute weight

The fact that you can select the most appropriate mode ensures a seamless integration into your standard laboratory operating procedure. 

The tank stirrer option makes sure that LeDoser performance is constant for high and low throughput. 

LeDoser is also LIMS-ready, and the data transfer is simple and straightforward.

Automation

The automated and constant weighing eliminates calculation errors and fatigue for increased accuracy and reproducibility. 

LeDoser minimizes repetitive strain injuries (RSI) arising from weighing-related tasks, hence improving the operators' safety.

Other benefits include:

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

Fluxes and chemicals

Borate fluxes and chemicals

Your first choice to fuse samples for XRF, ICP and AA analysis

As the one-stop shop in fusion and the world leader in the production of borate fluxes, Claisse develops high-quality chemicals that are easy to use and that ensure no contamination.

Offered in two grades of purity (pure 99.98+% and ultra pure 99.995+%) and available with or without non-wetting agents, our lithium borate fluxes are homogeneous and available in bead format.

Use Claisse lithium borate fluxes to:

  • Avoid crystallization
  • Reduce the incidence of glass sticking to the platinumware
  • Avoid cracking

Fusion monitor

Quick and error-free proactive monitoring for your fusion instruments

XRF laboratories must assure the quality of their analytical results and ensure accurate and precise data by using quality control sample regularly.

Obtaining the wrong analytical results can affect manufacturing and commercial decisions which can be very costly. Moreover, the Fusion-XRF process remains offline until the source of the variability is thoroughly identified and eliminated. When the analytical results are found to be outside the predefined criteria, planned actions must be taken. Since the analytical results can be affected by a large number of factors, troubleshooting steps may oftentimes become expensive and time consuming.

Molds & crucibles

Platinum molds and crucibles

Labware is of critical importance in sample preparation by fusion. Malvern Panalytical offers molds and crucibles made of 95% platinum are 5% gold. They are available in a wide range of sizes and thicknesses to help you obtain the best analytical results.

We also offer nickel and zirconium crucibles for peroxide fusion.

Malvern Panalytical fusion instruments were developed to be used with specifically designed platinumware. All our platinum accessories have been tested and engineered to provide:

  • The best mixing performance.
  • Longer lifetime.
  • Higher success rates in preparation of glass disks.
  • Perfect compatibility with our fusion instruments.
