Endotoxin-sensitive preparation
The endotoxin specification adds a biological-contaminant criterion beyond the ionic water-quality reading.

Laboratory Ultrapure Water System – ST-LPW07 Series supplies laboratory water with separate controls for dissolved ions, organic background and endotoxin. It helps reagent-preparation work avoid treating a good resistivity reading as the complete description of water quality.
The compact configuration lists a TOC limit of 5 ppb together with an endotoxin limit. Those are meaningful selection details for methods sensitive to both contaminant groups; the hourly production options should then be matched to the laboratory's collection pattern.

FEATURES AND BENEFITS
How it helps
Bench installation
The listed compact dimensions help reserve space for the main unit without assuming its service connections or consumable-access clearance.
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
Select for organic and endotoxin requirements
Preparation quality
Assess organic background and endotoxin together for the intended reagent procedure rather than selecting from the resistivity reading alone.
Compact installation
Match the production configuration to repeated batch demand and reserve space for feed, drain and service connections around the listed housing.
