Modular furnace for instant on-site maintenance*

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.

Fully modular power system and zone control

Each furnace zone is powered by its own power module. The temperature inside the furnace is uniform.

Circular agitation motion allowing faster sample* dissolution

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.

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 inovative chamber allows an intermediste 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 retaining 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
