3. General information
Biosan Labaqua is Ultrapure water purification system which requires external water
tank that use tap water as feed water (tap water system). There are three models available:
Labaqua Trace, Labaqua HPLC and Labaqua Bio.
Water purification system Biosan Labaqua produces pure water that complies with
ISO 3696 Grade II and Grade I water requirements.
Pure (ISO 3696 Grade II) water applications include, but are not limited to:
Feed for laboratory equipment (washing machines, clinical analyzers, humidifiers,
autoclaves, hydrogen gas generators);
Manufacturing of chemical and biochemical reagents;
Buffer preparation;
Microbiological media preparation;
In some cases - sensitive analytical techniques (e. g. atomic absorption, ICP-OES);
Wet chemistry;
Spectrophotometry.
Ultrapure (ISO 3696 Grade I) water applications include but are not limited to:
High sensitivity analytical techniques (ICP-MS);
High performance liquid chromatography;
TOC analysis
Molecular biology;
Cell culture.
