Laboratory Ultrapure Water System – ST-LPW01 Series provides both RO and ultrapure water from a floor-standing laboratory unit, keeping routine water collection and more sensitive preparation at one supply point.
The three output models increase storage alongside production rate. This matters when several users draw water in a short period: the tank handles the immediate draw, while production capacity determines how quickly that reserve is replenished.
MODELS AND DIMENSIONS
Available output models
| Model | Production rate | Storage tank |
|---|---|---|
| ST-LPW01-040 | 40 L/h at 25°C | ≥40 L moulded hygienic water tank |
| ST-LPW01-060 | 60 L/h at 25°C | ≥60 L moulded hygienic water tank |
| ST-LPW01-100 | 100 L/h at 25°C | ≥100 L moulded hygienic water tank |
Production-rate ratings are stated at the temperature shown in the table.
MODEL DIFFERENCES
Which configuration fits the task
ST-LPW01-060
At 60 L/h, both replenishment and the minimum tank capacity rise to 60 L, giving more reserve for a longer preparation session.
ST-LPW01-100
The 100 L/h configuration includes a tank of at least 100 L; this is the option to assess when larger batch draws and sustained consumption occur together.
FEATURES AND BENEFITS
How it helps
Two dispensing duties
The separate RO and UP dispensing rates allow routine collection and higher-purity preparation to be planned independently.
Low organic background
The specified TOC and endotoxin limits address contaminants that a resistivity reading alone does not describe.
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
Plan production and reserve together
Shared laboratory collections
Choose the matched production and hygienic-tank configuration around the largest collection batch and how soon the next user needs water.
Separate RO and UP duties
Assign routine rinsing and sensitive preparation to their required outlet qualities, then allow floor space for the cabinet and tank access.
