Laboratory Ultrapure Water System – ST-LPW12 Series prioritizes low organic background in laboratory water used for sensitive preparation. It combines high-resistivity water with a listed TOC limit so buyers can assess both ionic and organic contamination.
Unlike versions whose distinguishing requirement is endotoxin control, this configuration's useful published distinction is the 3 ppb TOC limit. Its 40–120 L/h model choices address replenishment duty within the common housing and dispensing arrangement.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW12-050
At 50 L/h, the model gives a small increase in replenishment for a schedule that is marginally too demanding for 40 L/h.
ST-LPW12-060
The 60 L/h version is a middle-low output choice for regular analytical preparation, with the same specified TOC limit as the larger versions.
ST-LPW12-070
The 70 L/h configuration fills the gap between 60 and 80 L/h when matching production to measured water consumption.
ST-LPW12-080
The 80 L/h model doubles the smallest rating, giving more recovery capacity for repeated reagent and sample-preparation batches.
ST-LPW12-090
The 90 L/h version adds output for longer preparation sessions without the full step to 100 L/h.
ST-LPW12-100
At 100 L/h, the selection emphasis is sustained consumption across consecutive batches rather than a different level of water purity.
ST-LPW12-110
The 110 L/h rating provides additional recovery between heavy draws where the 100 L/h model would have little spare production time.
ST-LPW12-120
The 120 L/h option offers the series maximum production for the busiest water-use schedule; it retains the common low-TOC specification.
FEATURES AND BENEFITS
How it helps
Organic-sensitive methods
A low TOC requirement helps select water for preparation where organic impurities can contribute to background signals.
Output steps
The production-rate options support a measured increase in daily water use while preserving a common installation envelope.
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
Choose organic quality before output
Analytical background
Match the method’s TOC requirement to the listed low-organic specification before choosing among the production capacities.
Frequent preparation
Use the model output steps to cover recurring collections within the working day, with the compact housing and feed-water connections planned at the bench.
