Laboratory Ultrapure Water System – ST-LPW03 Series combines low-ion water production with UV treatment and ultrafiltration for laboratory preparation that must address organic and biological contaminants as well as dissolved salts.
The listed UV wavelengths and 5,000 Da ultrafiltration cut-off distinguish this configuration from a basic RO and deionization unit. Two housing formats are listed, so both the treatment requirement and available installation space matter when selecting the assembly.
MODELS AND DIMENSIONS
Available output models
| Model | Production rate |
|---|---|
| ST-LPW03-020 | 20 L/h at 25°C |
| ST-LPW03-040 | 40 L/h at 25°C |
| ST-LPW03-060 | 60 L/h at 25°C |
| ST-LPW03-100 | 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-LPW03-040
At 40 L/h, water is produced at twice the 20 L/h rating, reducing replenishment delays when preparation batches become more frequent.
ST-LPW03-060
The 60 L/h version provides the intermediate output for sustained reagent and analytical preparation across a working session.
ST-LPW03-100
The 100 L/h model is the highest-output option for heavier repeated draws; it retains the same UV and ultrafiltration treatment functions.
FEATURES AND BENEFITS
How it helps
UV and UF serve different tasks
UV treatment addresses susceptible microorganisms and organic compounds; ultrafiltration provides a separate barrier for larger molecules.
Four replenishment rates
The output choices increase water production for busier preparation schedules without changing the listed common water-quality requirements.
APPLICATIONS
Where it is used
Reagent preparation with biological-contaminant limits
Use for preparation methods whose full endotoxin and water-quality requirements match this configuration.
SYSTEM SELECTION
Choose the treatment and housing format
Contaminants relevant to the method
Compare the specified organic, endotoxin and microbial requirements together when deciding whether this combined UV-and-UF treatment fits the preparation method.
Bench or floor position
Select the housing format and production model together so the chosen unit fits the installation position and repeated collection schedule.
