Using distilled / deionized / demineralized / high purity water
- abbreviated to DI-water 

What is DI-water?
Compared with drinking water DI-water contains no troublesome ions such as hardness creators (calcium, magnesium) or other ions except H+ and OH- (H2O). The various expressions for DI-water have their origins in the way it is produced. Distilled water is, as its name says, produced by distillation. Deionized or demineralized water is obtained by passing water through ion exchangers in such a way that all ions except H+ and OH- are deprived from the water. Another way of producing DI-water is by osmosis, whereby water is led through a semipermeable membrane that only allows high purity water to pass.

DI-water without additives in ultrasonic baths
Do not use DI-water directly in ultrasonic compact cleaners (AISI 304) without appropriate additives such as STAMMOPUR/TICKOPUR, as this leads to intensifi ed cavitation erosion right through to pitting on the base of the tank. If the procedure absolutely requires the use of the DI-water without additives, an insert vessel must
always be used additionally. Compared to tanks made of stainless steel 1.4301 (AISI 304), a lower erosion is to be expected when using DI-water in devices with welded oscillating tanks and immersible transducers made of stainless steel 1.4571 (AISI 316 Ti).

DI-water with additives in ultrasonic baths
The use of DI-water with appropriate cleaners or disinfectants is advantageous in all ultrasonic equipment. The cleaning is more intensive, so that in many cases the dosage of cleaners or disinfectants can be reduced compared to the use of drinking water.
