Laboratory Ultrapure Water System – ST-LPW09 Series provides a compact source of high-resistivity water with multiple production-rate choices for shared laboratory preparation. It reduces repeated container filling away from the bench by producing water near the point of use.
This series separates the output choices into steps from 40 to 120 L/h. Those steps change replenishment capacity; the common dispensing rate remains a separate figure for how quickly a user fills a vessel.

Select output capacity from daily consumption and peak dispensing demand.
MODEL DIFFERENCES
Which configuration fits the task
ST-LPW09-050
At 50 L/h, this intermediate step provides more recovery margin than 40 L/h without moving directly to the 60 L/h version.
ST-LPW09-060
The 60 L/h option suits a steadier pattern of water preparation, with 20 L/h more production than the entry model.
ST-LPW09-070
The 70 L/h configuration offers a smaller capacity increment when consumption has outgrown 60 L/h but does not require the 80 L/h step.
ST-LPW09-080
The 80 L/h version doubles the entry production rating, relevant when repeated batch draws continue through much of the working session.
ST-LPW09-090
At 90 L/h, the additional replenishment margin can accommodate a busier preparation schedule before stepping up to 100 L/h.
ST-LPW09-100
The 100 L/h model provides a higher sustained supply for closely spaced draws; hourly production remains separate from tap delivery speed.
ST-LPW09-110
The 110 L/h option bridges the two highest output levels for demand that leaves insufficient recovery time at 100 L/h.
ST-LPW09-120
The 120 L/h configuration is the highest production choice, for the largest cumulative demand within this compact series.
FEATURES AND BENEFITS
How it helps
Incremental production choices
Intermediate output models allow daily demand to be matched without jumping immediately to the largest production rate.
Installation envelope
The shared housing dimensions support a consistent equipment position across the output range.
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
Set replenishment around repeated collections
Production choice
Choose the hourly-production step from total consumption and the time available between batches, keeping the outlet’s separate dispensing rate in the calculation.
Bench services
Keep feed-water and maintenance connections accessible around the compact housing so the supply can be serviced at its intended collection point.
