Laboratory Ultrapure Water System – ST-LPW13 Series supplies low-organic-background water from a compact system for laboratory preparation. Online resistivity monitoring provides an ionic-quality check, while the TOC specification addresses a different contaminant group.
Its listed production options and 650 × 530 × 420 housing format allow the unit to be considered within an existing bench layout. The practical choice is the required water quality and replenishment rate, rather than treating a small cabinet as evidence of low output.

FEATURES AND BENEFITS
How it helps
Routine and final preparation
The RO and ultrapure-water specifications allow tasks to be assigned according to the water each method actually requires.
APPLICATIONS
Where it is used
Analytical sample and solution preparation
Match the organic and ionic limits to the method to reduce unwanted background introduced with preparation water.
SYSTEM SELECTION
Fit low-organic supply into the bench layout
Preparation task
Check the ionic and organic requirements of the intended preparation against the two outlet specifications, then identify which tasks need polished water.
Installation and use
Reserve the listed cabinet envelope plus connection access, and choose production for the laboratory’s batch pattern rather than cabinet size alone.
