Logo Ultrasonic Cleaning Ultrasonic cleaning can remove contaminants--such as grease, oil, wax, fluxes, fingerprints, oxides and other deposits--from visible and invisible surfaces, holes and cracks. In general, if an item can be cleaned with a liquid, it can be cleaned much faster and more thoroughly with an ultrasonic cleaner. It may not be possible to clean certain intricate and complex parts without the use of an ultrasonic cleaner.Ultrasonic can deal with physical problems but cannot deal with chemical problems. These items will become duller over time and they are usually oxidized or produce certain types of chemicals.If the silver has turned black, simple ultrasonic cleaning is not enough, need to add professional cleaning agent.Different ways of cleaning: General Cleaning - only use warm and fresh water, warm water's temperature is about 50 centigrade. Enhanced Cleaning - add a few drops of standard liquid soap or detergent into the water, some basic non-acidic cleaning agents can be used as well. Extensive Cleaning - Removing tarnish, carbon and rust from non-plated metals. It is recommended to use specialist cleaning solution in associated using Ultrasonic cleaner. Product details Product name:Derui ultrasonic DR-DS20 Ultrasonic Power:80W Heating Power:100W Voltage:110V-120V Material:Stainless Steel SUS304 Tank Capacity:2L / 150*138*100mm In reality its about 1.5L for water (when its filled to the very top) Frequency:37KHz TransducerPC:1*80W Unit Weight:2.1Kgs 1) Temperature control knob (cleaning liquid temperature setting), Timer control knob (cleaning time setting). 2)On/Off& Memory button. 3)Degas Remove the air in the water, reduce the resistance of air bubbles generated by ultrasonic cavitation reaction, and improve the cleaning efficiency. 4)Sweep The ultrasonic sound field distribution is more uniform and the cleaning is more comprehensive. Sweep Jewelry Ultrasonic Cleaner Degas and Sweep features are specifically designed for fine items like jewelry circuit boards. Note: the cleaning process needs to add professional cleaning agent, so as to achieve better cleaning effect. Warning Please operate according to the specifications of the manual, especially pay attention to the red text in the manual. Cleaning jewelry items: For diamond inlaid jewelry, extended periods of cleaning are not suitable; if the cleaning time is too long, the diamonds may fall off. These items will become duller over time and they are usually oxidized or produce certain types of chemicals.If the silver has turned black, simple ultrasonic cleaning is not enough, need to add professional cleaning agent. Tank material is SUS304 1mm,but do not use strong acid, alkaline or corrosive liquids, strong acid and alkaline cleaning will cause corrosion,rust and even puncture of tank or machine body. If you want to use strong acid and alkaline cleaning agent, please use a beaker, pour the acid and alkaline liquid into the beaker, and put the items that need cleaning into the beaker, then put the beaker in the basket. 2L ultrasonic cleaner 3L ultrasonic cleaner 3L ultrasonic cleaner with power adjustable Add to Cart Add to Cart Add to Cart Customer Reviews 4.2 out of 5 stars 26 4.1 out of 5 stars 10 3.7 out of 5 stars 7 Price $120.00$120.00 $153.30$153.30 $158.00$158.00 Model DR-DS20 DR-DS30 DR-P30 Ultrasonic Power 80W 160W 160W Heating Power 100W 150W 150W Frequency 37KHZ 37KHZ 37KHZ Tank Size 2l/150*138*100mm 3l/238*138*100mm 3l/238*138*100mm Basket size 130*120*65mm 218*120*65mm 218*120*65mm Timer 0-30min 0-30min 0-60min Temperature 30-80℃ 30-80℃ 30-80℃ Product Show The Front Mechanical knobs control time and temperature, button control switches, and Degas and Sweep features.
