The new F1 and F2 induction fusion units have been specially developed to speed up and facilitate the process of preparation of glass disks for their analysis by XR, and AA solutions for ICP. They can produce, fast and accurately, beads and dissolutions with classical fl uxes (Borates) as well as to undertake high quality fusions in non oxidized elements using peroxide. They are effective both in high and low temperatures. The F2 model has got two working stations completely independent from one another, it is literally like having two fl uxes within a single unit. Following the trend of removing combustion gas from laboratories, the F Series represents a technological breakthrough in the fusion units, as it heats up the samples by induction homogeneously, quickly and effi ciently. These are highly automated units with capacity to control and monitor in real time the fusion process of one or two samples separately. To this innovative heating system we add a constant temperature check up device and a good work of software. The result is a unit able to exhaustively control and change the fusion process of each of the samples, in real time.
The F Series induces electrical power through a coil – no flames and no contact -, which, producing an electromagnetic field, can heat up the crucible efficiently and very quickly, causing the fusion of the sample mixed with the flux in very short time and homogeneously. When the heating time we allocated for this step fi nishes, the sample is poured automatically to the left, in the solutions beaker, or to the right, in the mould heated previously.
The heating process by induction is noticeably a faster operation, cleaner, and more accurate and reliable than any other system. It enables the user to reach high temperatures (1200ºC) in just a few seconds and to control them effectively. The changes in the temperature of the sample are applied right away, so you can truly have the control of the fusion process in real time. The only parts of the unit that do actually become hot are the crucibles and the moulds: this allows the unit to reduce the time between fusion cycles, as it does not need cooling large surfaces.
- An optical pyrometer focused to the base of the crucible
carries out a check up of the fusion temperature all the
- The programmable stirring system ensures an excellent
homogenization of the samples during the heating up
- Sample Preparation • Equilab • 5
- You can also adjust the refrigeration system for the crucibles
and the moulds, thus accelerating noticeably the
cooling down of the same.
- Flexible process for stirring dissolutions.
- Includes an exclusive system to remove gases that enables
the unit to be placed anywhere, not needing extractor
- As a safety measure, the door is locked automatically if
the temperature inside supposes a risk for the user.
- The coil is cooled down using a closed water circuit with
a small refrigeration device (300W) – no water or coolers
needed – able to maintain up to 2 modules / 4 coils working
simultaneously (2 crucibles and 2 moulds).
Each of the fusion modules can work synchronized with the rest or independently with different programs, for example, if undertaking samples of varied nature. This freedom lets the user prepare new samples as the others fi nish their cycle, increasing thus the productivity in the laboratory.
The induction system is a fast heating method with a very moderate electricity consumption. Maximum consumption 4000W, tested with the simultaneous heating of two crucibles and two plates.
- Beads: up to 6 / 8 per hour with each module
- Dissolutions: up to 16 per hour with each module
- Fusions/oxidations (peroxide): up to 16 per hour and module
