How should the Helix fusion chamber be cleaned?
The beaker and the core of the Helix fusion chamber should be rinsed thoroughly with distilled water immediately after the experiment to prevent drying of sample residues. If it is severely contaminated, the Helix fusion chamber can be cleaned briefly in an ultrasound bath (possibly with a cleaning additive like Edisonite-Super, for example) or with a very soft (tooth) brush. If using a brush for cleaning, you must ensure that you brush in the direction of the winding, otherwise the electrodes may be moved making the Helix fusion chamber unusable. Sterilization can be effected by treating with ethanol (70 %, non-denatured). To this end, the beaker is filled with 250 µl of ethanol and the core screwed into the beaker. After 10 seconds, the core is unscrewed and the alcohol can be removed. For subsequent drying, place the beakers and the core in the stand under sterile conditions (e.g. clean bench).
