The K2 Prime fluxer: What it does
Watch the video
The K2 Prime is pre-loaded with various fusion methods that can be used as is, or can be customized. All fusion methods can be saved, renamed, deleted or copied, just like computer files. Only the preset methods are protected to avoid accidental overwriting.
Upon turning the instrument on, the furnace door opens, the platinumware holders move forward and out of the furnace, and the door closes. The heater then automatically reaches the user-preset holding temperature and is ready to fuse about 15 minutes after being turned on.
Up to six (6) platinum crucibles are loaded with a few grams of powdered sample, an appropriate flux and often other agents. The crucibles are inserted into the crucible holders.
Platinum molds are then installed onto the mold holder.
When the user instructs the K2 Prime to launch the actual fusion, the oven door automatically opens, the platinumware holders enter the oven, the door closes and all heating steps are automatically started in sequence. Temperature is constantly monitored and displayed.
The back-and-forth rocking of the crucible holder continuously mixes the flux with the sample.
When the flux melts, it starts dissolving the sample. When all sample is dissolved, the oven door opens, the platinumware holders move forward and, during the time the door closes, the crucibles are tilted forward to empty their contents into the molds.
Fans located underneath cool the molds, while the oven remains powered, to gain time. When the molds are completely cooled, the user picks up perfectly homogenous glass beads, ready for analysis by XRF.
For solution preparation, the hot melt is poured into unbreakable beakers (instead of molds), which contains an acid stirred by an optional magnetic system.
