Elix35, MilliQ Academic

There are several types of water, depending on what you need. This includes a range from Type III/IV all the way up to Type I/I+ for more sensitive applications.

Type II Water also known as Pure water has high levels of purity and low conductibility (<1 µS/cm), but the resistivity is not necessarily 18.2 MΩ^cm-1.

It is not considered “ultrapure,” but still pure enough for specific use.

If needed, this water can be filtered with a 0.22 µm filter.

It can be used for a wide range of applications such as

• general Lab practices in Microbiological Analysis;
• solution and media preparation;
• media preparation and dialysis process;
• rinsing glassware;
• heating baths

Type I Water (also known as Ultrapure water with MilliQ grade) is the purest water that can be produced. It has high levels of purity, low conductibility (<0.056 µS/cm) and 18.2 MΩ^cm-1 resistivity. This water is 0.22 µm filtered.

It’s used for the most critical applications and advanced analytical procedures, for example:

• Graphite Furnace Atomic Absorption Spectrometry (GFAAS);
• Gas Chromatography (GC);
• Liquid Chromatography for small molecules and macromolecules separation, including High and Ultra Performance Liquid Chromatography (HPLC and UPLC)
• Liquid Chromatography and Inductively Coupled Plasma Mass Spectrometry (LC-MS and ICP-MS)
• Cell and Tissue Cultures
• Molecular Biology

MilliQ water should be taken as needed in cylinders, bechers or small laboratory containers.

At the end of the session, check that the taps are closed. In case of problems/alarms, please notify to the technical staff.
