# K2 Prime fluxer

Automated fusion fluxer for fusion digestion of metal samples, slags and refractory materials prior to XRF or ICP analysis, reproducible between operators.

**Former model.** The K2 Prime has been replaced by the Katanax X-series (X-100, X-300, X-600). We still service existing K2 Prime installations with spare parts and calibration. For a new investment, we recommend X-300 (https://labsense.se/sortiment/katanax-x-300/) as the closest equivalent.

## Description

The K2 Prime is a two-position gas-fired fluxer that produces beads and solutions with the highest possible reproducibility. Programmable cycles control temperature, agitation, and casting to ensure each bead has identical geometry and homogeneity.

The design withstands continuous operation in industrial labs. Pt/graphite crucibles are interchangeable and compatible with all common lithium borate fluxes. For smelters, K2 Prime is a standard solution that makes fusion digestion a predictable part of the analysis chain.

## Service & support

Fusion digestion requires reliable crucibles, moulds and precisely controlled induction — otherwise the entire XRF workflow is affected. Our Katanax technicians service the fusion system so daily operation and sample repeatability hold across shifts.

- Annual check of induction, temperature profile and motion axes with documented protocol.
- Stocked platinum and graphite crucibles, casting moulds and lithium-based flux in the Nordics.
- Preventive replacement of wear parts (lift arms, sensors, heat shields) before failure.

## Common comparisons

Katanax K2 Prime is a compact fusion fluxer (fusion instrument) for XRF sample preparation. Common alternatives that customers evaluate in parallel: Claisse TheOx, Claisse Eagon 2 and M4 (Malvern Panalytical), Herzog HAG / HSF, and XRF Scientific Phoenix / xrFuse. K2 Prime uses induction heating — no open flame — with a fast cycle and programmable fusion profile.
