Laboratory Ultrapure Water System – ST-LPW21 Series supplies a floor-standing laboratory water point with online quality monitoring. It supports analytical and routine preparation by making RO and high-resistivity water available within the same work area.
The specified microbial and particle values help assess the collected water beyond the conductivity reading. Output steps from the same cabinet allow the replenishment rate to be matched to how frequently staff prepare solutions and rinse equipment.

FEATURES AND BENEFITS
How it helps
Particle and microbial criteria
The additional values address contamination categories that a resistivity measurement cannot directly count.
APPLICATIONS
Where it is used
Shared laboratory water collection
Place a monitored water point near repeated preparation and rinsing tasks, with each outlet selected for the task’s required water quality.
SYSTEM SELECTION
Match monitored supply to the laboratory
Collected-water quality
Assess ionic, microbial and particle requirements separately for the solutions and rinsing tasks planned at this supply point.
Shared collection point
Size production for overlapping collections and locate the floor-standing cabinet where feed pressure, vessel access and service space can be maintained.
