## Description

The X-300 is an electrically powered fluxer that doesn't require gas installation, making it ideal for labs where gas safety is complicated. Three simultaneous crucibles provide good capacity without requiring large-scale lab space.

Lithium borate flux in an inert atmosphere provides complete homogenisation of sulphides, oxides, and refractory samples. Program control ensures reproducibility and full documentation of each fusion.

## 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.
