Lower TOC option
The tighter organic limit provides a useful distinction for methods that are sensitive to trace carbon compounds.

Laboratory Ultrapure Water System – ST-LPW08 Series serves laboratory preparation needing the lower organic-background option within this compact water-system group. RO and ultrapure water remain available for their different preparation tasks.
Compared with the closely related 5 ppb TOC configuration, this model lists a 3 ppb TOC limit while retaining an endotoxin requirement. That difference matters where organic background contributes to blanks or analytical interference; it is not an increase in dispensing speed.

FEATURES AND BENEFITS
How it helps
Separate contamination measures
Resistivity, TOC and endotoxin specifications describe different requirements rather than interchangeable purity scores.
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 low-organic configuration
Contamination priorities
Use this lower-TOC option where organic background is part of the preparation requirement, alongside the stated endotoxin and ionic specifications.
Working layout
Choose production for the size and frequency of water collections, with the compact cabinet positioned close to preparation and accessible for servicing.
