The present disclosure provides purified pharmaceutical preparations comprising oxidized SkQ1, wherein no individual impurity exceeds 1. In the deposition of an amorphous silicon film using a sputter method, a condition is provided with a frequency of 15 to 25 kHz and a deposition power of 0. The template may be a junction template allowing several wells to be drilled from a single template, or allowing the template to be connected by one or more drilling conduits to further templates such that a wide area of the seabed can be covered for a single drilling riser conduit. The respirator bellows communicate with the respirator mask via the respirator conduits.
