How to clean quartz sub boiling distilled water purifier

1、 General dirt cleaning:

1. Cut off the power and water sourcesBefore cleaning, be sure to cut off the power supply of the quartz sub boiling distilled water heater and close the tap water valve to ensure safe operation.

2. Add concentrated hydrochloric acidAdd to the horizontal flask100mlConcentrated hydrochloric acid, if there is a lot of scale accumulation, the amount of hydrochloric acid can be appropriately increased. Mix hydrochloric acid with the water in the bottle to dissolve scale and other dirt, and soak for a few minutes.

3. Release the solution and rinseAfter soaking, release the hydrochloric acid solution through a water level gauge. Then rinse the flask several times with tap water. To remove trace amounts of hydrochloric acid, shake the flask back and forth to clean even the difficult to clean dead corners.

4. Discard the initial distilled waterWhen distilling again, begin 10 The water distilled within minutes should be discarded as there may be trace impurities remaining1.

2、 Serious dirt or chemical pollution cleaning:

1. Soak in aqua regiaThe volume ratio of hydrochloric acid to nitric acid is 3：1Immersion distiller 24 Hour.

2. Hydrofluoric acid etchingIf the long-term use of tap water for direct purification leads to severe scaling, or if pollution is caused by the addition and purification of chemical reagents, it can be soaked in aqua regia and then reused5%Hydrofluoric acid is used for etching treatment, with the brightness of the distiller as the standard. Be careful not to soak excessively to avoid making the surface of the distiller rough.

3. rinse thoroughlyAfter etching is completed, rinse the distiller with deionized water to ensure that any remaining chemical reagents are washed clean and reach a state of equilibrium purification.
