Hi, Pavankumar. Distilled water is water that has been boiled away to steam and recondensed back to water, the principle being that many contaminants are left behind in the process. Millipore is a supplier of laboratory equipment, including water filtration systems and ultrafiltration systems. I suppose "Millipore water" could mean water that has been passed through any of a wide variety of systems, as long as Millipore was the supplier of the system, but in terms of the final water quality the term strikes me as meaningless. Good luck.

In the lab, Millipore water would almost always refer to deionized water. It implies that Millipore equipment was used, but that is not an iron clad guarantee.
Caution, there are 4 grades of lab water and each one costs more. Normal distillation will normally only meet the lowest grade. Double or triple distillation in the proper equipment will go higher. The highest grade will actually very very slowly dissolve common lab glass. Very well maintained and regularly checked top grade water can only be reached with excellent DI equipment. Millipore will reach that level to start.
