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.
The main furnace can be removed and replaced within minutes with no special tools. You can resume operation without a lengthy cooldown and on-site repair. The entire heating assembly comes as a snap: elements, insulation and sensors, nothing is left behind.
Each furnace zone is powered by its own power module. The temperature inside the furnace is uniform.
Borate fusion is a dissolution technique. If you stir better, you dissolve faster, it’s that simple. Our fully circular and rapid motion will reduce repeat and save up to 30% of dissolution time.
Several sample types require a pre-oxidation step, which is challenging with a furnace-type fluxer. Our inovative chamber allows an intermediste temperature step.
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.
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
