Laboratory Ultrapure Water System – ST-LPW05 Series provides a smaller laboratory water-production format for work involving both routine rinsing and low-background reagent preparation. Online water-quality readings help staff decide whether the outlet is ready for their method.
This configuration combines a compact housing with output choices from intermittent bench use to heavier daily demand. The TOC limit is a separate selection criterion from resistivity, because dissolved organic background can affect an analytical method even when ionic purity is high.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW05-010
The 10 L/h model doubles the entry production rate, giving a small-volume workstation more recovery capacity during the day.
ST-LPW05-020
The 20 L/h version supports a more regular preparation schedule, with twice the production of the 10 L/h option.
ST-LPW05-040
A 40 L/h rating provides the next step when several preparation batches leave the lower-output models too little time to replenish.
ST-LPW05-060
The 60 L/h model adds sustained production for repeated analytical preparation while retaining the same listed low-TOC water specification.
ST-LPW05-100
The 100 L/h version is the capacity choice for the greatest cumulative water use; select it for replenishment demand rather than a different dispensing speed.
FEATURES AND BENEFITS
How it helps
Broad output choice
Lower-output versions suit spaced collections; higher-output versions replenish water more quickly between preparation batches.
Organic and ionic checks
The specified TOC and resistivity address different types of contamination and should both be matched to the method.
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
Balance analytical demand and bench space
Organic-sensitive preparation
Compare the method’s organic-background requirement with this unit’s TOC specification as well as its ionic-water quality.
Collection rhythm
Choose a production model for the interval between preparation batches, allowing service access around the compact cabinet at the bench.
