Laboratory Ultrapure Water System – ST-LPW26 Series combines UV treatment and ultrafiltration for laboratory preparation with several trace-contamination requirements. In addition to resistivity, the table includes TOC, endotoxin and enzyme-related values relevant to method selection.
The DNase, RNase and protease limits are useful distinctions from the more general laboratory-water configurations. A floor-standing housing and three output choices provide a dedicated preparation-water point without reducing the decision to production capacity alone.
MODELS AND DIMENSIONS
Available output models
| Model | Production rate |
|---|---|
| ST-LPW26-040 | 40 L/h at 25°C |
| ST-LPW26-060 | 60 L/h at 25°C |
| ST-LPW26-100 | 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-LPW26-060
The 60 L/h model adds replenishment for preparation batches that follow more closely during an analytical or life-science session.
ST-LPW26-100
The 100 L/h option provides the largest recurring water volume in the series; treatment functions remain the same, so the difference is recovery capacity.
FEATURES AND BENEFITS
How it helps
Enzyme-related requirements
The separate enzyme limits help assess water for sensitive reagent and molecular-work protocols.
Combined final treatment
The listed UV and UF stages address different contamination mechanisms before water is collected.
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 for enzyme-sensitive preparation
Reagent protocol
Check the procedure’s DNase, RNase and protease requirements against this configuration together with its organic and endotoxin specifications.
Dedicated collection station
Match the output model to preparation batches and leave a serviceable floor position for the UV-and-UF treatment assembly.
