Gentle cleaning with digital technology for home and laboratory. Modern cleaning with ultrasound is the most thorough method for the intensive cleaning of materials of all kinds. The principle is based on the fact that the cleaning liquid is set into high-frequency oscillations, which removes even the smallest particles of dirt from inaccessible places. It is suitable for cleaning jewellery, spectacles, shaver heads of electric razors, coins and medals, dentures, braces, tattoo needles, piercing jewellery, ink printer needle heads, and much more. The cleaning time is adjustable depending on the degree of soiling.
