Laboratory Ultrapure Water System – ST-LPW25 Series provides monitored high-resistivity water from the 512 × 390 × 445 mm compact housing. It fits a bench-area supply arrangement where water is collected in small batches throughout the day.
The standard pressure tank buffers those collections, and the production models cover different replenishment needs. Microbial and particle values remain separate from the ionic reading, helping the laboratory compare the water requirement of its actual preparation method.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW25-010
The 10 L/h model provides more recovery for repeated small analytical batches within the same compact format.
ST-LPW25-015
The 15 L/h configuration offers a smaller intermediate capacity step for demand between 10 and 20 L/h.
ST-LPW25-020
At 20 L/h, the system is a higher-output choice for preparation work repeated through a normal working session.
ST-LPW25-040
The 40 L/h version doubles that production rate for closer-spaced batches and more cumulative use.
ST-LPW25-060
The 60 L/h option provides additional replenishment during sustained analytical preparation, while the listed water-quality criteria remain unchanged.
ST-LPW25-100
The 100 L/h model has the greatest output but the same standard 5 gal tank; production capacity and the storage needed for a large draw should be selected separately.
FEATURES AND BENEFITS
How it helps
Bench-area installation
The compact housing allows the production unit to be planned close to the collection point.
Rate versus reserve
The tank serves the immediate draw; the selected production model determines how quickly it can be refilled.
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
Size a bench-area water reserve
Water requirements
Compare the microbial and particle criteria with the actual preparation task alongside the final ionic specification.
Tank and output
Select the production step around the interval between collections, with the pressure tank and its tubing included in the bench-area layout.
