Laboratory Ultrapure Water System – ST-LPW22 Series provides a floor-standing RO and polished-water supply for preparation tasks within the stated 15–18 MΩ·cm range. It helps laboratories keep a monitored local source for repeated daily collections.
This version has a broader RO conductivity range than the higher-purity configurations in the same cabinet family. That water-quality distinction comes before choosing among the output capacities; a higher hourly output does not tighten the chemical specification.

FEATURES AND BENEFITS
How it helps
Shared physical installation
The common cabinet size keeps the water-service position consistent across the output choices.
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
Choose for the stated polished-water range
Task allocation
Use the published RO and polished-water ranges to assign compatible washing and preparation duties to the correct outlet.
Dedicated floor station
Match production to repeated collection volume and check inlet pressure at the proposed floor position while other water users are operating.
