1. Key Features of Claisse Fluxes

Claisse fluxes are manufactured through a unique process for unmatched purity and physical properties. They are:

• Fused and homogenous: Claisse borate fluxes consist of homogenous, spherical and vitreous particles. Each particle has the same composition. If a flux is not homogenous, segregation will affect the analytical accuracy of your analysis.
• 99.98+% pure and 99.995+% ultra pure: Claisse pure borate fluxes are guaranteed to contain less than 10 ppm of 15 selected elements. For ultra pure fluxes, the level of contamination is carefully controlled and analyzed for 30 selected elements and a detailed certificate of analysis is supplied with each order. Claisse ultra pure fluxes are clearly the purest on the market.
• High density: Claisse borate fluxes have a density of 1.4 g/cm3 as compared to 0.5 g/cm3 for powder fluxes. They never fill more than half of the crucible, even when fusions for large 40-mm disks are made, thus eliminating all risk of overflowing during agitation.
• Water free: Claisse fluxes have the lowest water content on the market (< 0.05%).
• Non-hygroscopic: because of their vitreous nature, Claisse borate fluxes are not hygroscopic. A major problem with absorbed humidity is loss of accuracy in your analytical results because of the induced error on the mass of flux weighed, therefore affecting the sample/flux ratio.
• 99.95% Non-hygroscopic: Since they are fused, Claisse borate fluxes are free of water. Their atmospheric absorption of H2O is less than 0.05%.
• Controlled Granulometry: Claisse fluxes are 100% less than 500 µm and contain no dust. Due to electrostatic forces, dusty fluxes stick to the weighing pan, the funnel and the crucible wall, resulting in a loss of flux, lower analytical accuracy and the formation of glass droplets on the wall of the crucible.
• Non-wetting agent integrated: Claisse fluxes are available with integrated Lithium bromide (LiBr) or Liththium iodide (LiI). Our experience has shown that the amount of non-wetting agent (NWA) added to the fusion by the analyst is not constant and this affects the analytical accuracy of the analysis. With the new fluxes that have the NWA integrated, the same amount of NWA is invariably added during fusion. In addition, these fluxes are easier to use because you do not have to add the NWA separately during the fusion process.
• Outstanding fluidity: Claisse borate fluxes are easier to handle and weigh.
• Available in Custom Blends: Claisse offers exclusively designed fluxes for your particular applications. Tell us your needs, and we'll supply your custom blend flux.
• Available from stock except for custom blends: If you are out of stock or have an urgent need, we will promptly ship your requested flux.
• Consistent quality: At Claisse, fine chemistry production is truly an exact science, starting with the discovery of a revolutionary new production technique making it possible to make reproducible batches each and every time. No need to stock large quantities of flux. No need for recalibration for each order of flux. With Claisse, you can always expect the same high quality of flux.
