TheMilli-QPlussystemisa stateoftheartwaterpurification
system,designedtoprovidethefinalpolishtowaterwhichhas
beenpretreatedbyprimarypurificationmethodssuchas

Thesystemprovidesultrapurewaterforthelaboratoryforuse
incriticalapplicationsrequiringtheabsenceofinterfering
inorganic,organic,particulate,ormicrobiologicalmaterial.
Asa resultofattentiontodesigndetail,plusstrictselection

exceedsType1 standardsforReagentGradeWater.
TheMilli-QPlussystemutilizesa patentedpurificationpack
concept. Thedesignofthispackensuresminimaldeadwater
