ST-LPW16-005
The 5 L/h model is the lowest-output choice for small, occasional ultrapure-water preparations; the standard pressure tank is 5 gal.

Laboratory Ultrapure Water System – ST-LPW16 Series supplies monitored RO and ultrapure water in a compact housing for laboratories needing both routine preparation and a higher-purity final water source. The stated heavy-metal value adds a useful selection criterion for ion-sensitive work.
The standard 5 gal tank buffers intermittent collection while the output choices set replenishment capacity. The cabinet stays compact; the larger output options are useful when batches are repeated more frequently, not because each litre is a different water grade.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW16-010
A 10 L/h rating provides twice the recovery capacity for a bench where small preparations recur throughout the day.
ST-LPW16-015
The 15 L/h version is an intermediate choice when 10 L/h leaves too little replenishment time but 20 L/h is unnecessary.
ST-LPW16-020
The 20 L/h model supports a more regular batch schedule without changing the standard pressure-tank size.
ST-LPW16-040
At 40 L/h, the production step is useful when several batches are prepared together rather than separated by long idle periods.
ST-LPW16-060
The 60 L/h option gives more replenishment during sustained preparation, with the same listed water-quality specification.
ST-LPW16-100
The 100 L/h version is the highest-output configuration; its standard 5 gal tank does not grow with production, so burst volume and recovery demand remain separate choices.
FEATURES AND BENEFITS
How it helps
Trace-ion requirement
The heavy-metal specification supplements bulk resistivity when assessing preparation for sensitive measurements.
Output matched to work rhythm
Small production options suit spaced draws; larger options reduce the time needed to restore the water reserve.
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
Arrange a compact preparation-water supply
Trace-ion requirement
Include the supplied heavy-metal value in the preparation-water decision when trace ionic contamination matters to the method.
Reserve and refill
Plan the external tank beside the compact unit, then select the output step around the largest collection and the time before water is needed again.
