Nieka Core 6 – Fusion Machine for XRF and ICP
The Core-6 is the achievement of a decade-long research program where nothing has been left behind.
With the Core systems, you will benefit from multiple inventions and the experience of Nieka users worldwide. The Core-6 mechanical systems are based on the proven Nieka platform: they are sturdy, efficient and easy to maintain.
Features
- Pre-oxidation chamber for true and efficient temperature ramping (patented), several sample types require a pre-oxidation step, which is challenging with a furnace-type fluxer. Our innovative chamber allows an intermediate temperature step.
- Filtered cooling air, the stream of air cooling the glass disks and internal electronics is fully filtered. Even in dusty environments, the Nieka Core system will deliver premium analytical purity.
- Cold crucible remaining bar, when the hot crucibles are moved out of the furnace for the pouring step, a special bar is waiting outside to hold them in place for the final tilt. Having such bar outside of the furnace reduces the contamination and failures associated with retaining bars inside the furnace
