Laboratory Ultrapure Water System – ST-LPW30 Series supplies RO and ultrapure water for analytical preparation from a floor-standing unit. It provides online ionic-quality monitoring together with a defined organic-background requirement.
This is the 20 ppb TOC configuration in the tall-cabinet group. It gives buyers a clear distinction from lower-TOC or ultrafiltration variants, while the three production capacities address how often water must be replenished during the working day.
MODELS AND DIMENSIONS
Available output models
| Model | Production rate |
|---|---|
| ST-LPW30-040 | 40 L/h at 25°C |
| ST-LPW30-060 | 60 L/h at 25°C |
| ST-LPW30-100 | 100 L/h at 25°C |
Production-rate ratings are stated at the temperature shown in the table.
MODEL DIFFERENCES
Which configuration fits the task
ST-LPW30-060
The 60 L/h option supplies more replenishment between repeated preparations, with no change to the listed final-water criteria.
ST-LPW30-100
At 100 L/h, this model provides the greatest sustained production for a busy batch schedule, rather than a different dispensing flow rating.
FEATURES AND BENEFITS
How it helps
Specified organic background
The TOC limit supports selection for methods whose tolerance is known instead of assuming all high-resistivity water is equivalent.
Dedicated filling station
The cabinet format supports a separate collection point for repeated solution preparation and routine water handling.
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
Choose an analytical water filling point
Organic background
Compare the method’s permitted organic background with the listed TOC value as well as final resistivity.
Floor-standing operation
Select production for recurring analytical batches and reserve a floor position that keeps collection and treatment-stage maintenance accessible.
