Overview

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.

Performing the weighing step manually is a very tedious and time-consuming task for employees working in a laboratory. LeDoser-12 solves this issue by precisely weighing the sample and dispensing the borate flux, thereby saving up to 90% of labour time related to this step. This instrument is a must-have in a laboratory since it ensures consistent and high-quality analytical results without users becoming distracted or tired.

Features and benefits

  • 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

  • Made of durable parts and contains a robust industrial-grade balance, preventing flux infiltration

  • Two piece carousel for easy crucible handling

  • LIMS ready: no manual data transfer

Why LeDoser-12?

LeDoser-12 is a LIMS-ready automatic dispensing balance that can be interfaced with a barcode reader to guarantee sample traceability and easy data transfer. It also avoids sample misidentification or inversion, a key to keeping high quality assurance. 

By eliminating the pre-weighing step, ensuring constant sample throughput, and prioritizing samples, LeDoser-12 instrument optimizes the synchronization of the sample preparation process and makes sure you get your samples ready just in time for fusion. 

Other benefits of LeDoser-12 instrument: 

  • Quick ROI
  • Low cost of ownership 
  • Safe and intuitive to use

Optimizing sample preparation

With LeDoser-12, your samples are ready just in time by eliminating the pre-weighing step and ensuring constant sample throughput.

The LeDoser-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.

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

Make your life easier, try our pre-weighed or customized borate fluxes.

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.
