Laboratory Ultrapure Water System – ST-LPW14 Series combines UV treatment and ultrafiltration in the smaller 580 × 390 × 490 housing format. It supplies laboratory preparation where organic and biological contamination must be considered along with dissolved salts.
The 185/254 nm UV unit, 5,000 Da UF cut-off and low TOC requirement identify the treatment configuration. Production choices then determine how quickly water is replenished between collections; they should not be confused with changes in treatment quality.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW14-010
At 10 L/h, the system replenishes at twice the entry rating, useful when small preparations occur more often.
ST-LPW14-020
The 20 L/h option supplies a more regular preparation routine while retaining the same compact cabinet and treatment stages.
ST-LPW14-040
The 40 L/h model is the next production step for grouped preparation batches with less time between draws.
ST-LPW14-060
The 60 L/h configuration adds replenishment capacity for a longer sequence of analytical or reagent preparation tasks.
ST-LPW14-100
The 100 L/h option delivers the highest production rating in this format, for the largest recurring demand using the same UV/UF treatment.
FEATURES AND BENEFITS
How it helps
UV plus molecular filtration
The two stages address different contamination mechanisms within the specified water-treatment process.
Smaller equipment position
The housing is substantially lower than the floor-standing versions, helping fit the treatment function into a bench-level service layout.
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 compact UV-and-UF treatment
Method-specific contaminants
Use the supplied TOC, endotoxin and enzyme-related requirements to assess preparation needing more than an ionic-quality reading.
Service access
Choose the replenishment model for the workload and keep the compact UV-and-UF unit accessible for its treatment-stage maintenance.
