Laboratory Ultrapure Water System – ST-LPW24 Series adds a dual-wavelength UV stage to a compact RO and ultrapure-water arrangement. It supports laboratory preparation that needs a defined ionic condition together with treatment directed at microbial and organic contamination.
This version retains the compact housing and 5 gal pressure-tank arrangement while listing 185/254 nm UV treatment. The TOC requirement remains the value in the table; the presence of a UV stage alone should not be treated as a different numerical water-quality grade.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW24-010
The 10 L/h version adds recovery capacity for small draws repeated more frequently during the working day.
ST-LPW24-020
The 20 L/h choice doubles that output for a steadier sequence of reagent preparation tasks.
ST-LPW24-040
The 40 L/h model provides a larger production step for batches drawn close together; UV treatment remains common to the series.
ST-LPW24-060
The 60 L/h option improves replenishment during a longer preparation session, without increasing the standard tank size.
ST-LPW24-100
The 100 L/h model is the maximum-output version; optional tank sizes can be considered separately when the concern is a large single draw.
FEATURES AND BENEFITS
How it helps
Dual-wavelength treatment
The UV stage has a different role from membrane separation and deionization, addressing susceptible organisms and organic compounds.
Buffered compact supply
The external pressure tank supports collection peaks without requiring a tall main unit.
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
Match UV-equipped supply to preparation
Treatment choice
Choose this UV-equipped configuration where the laboratory procedure calls for that treatment stage, while assessing water quality from the separate ionic and TOC values.
Compact assembly
Plan a position for the external pressure tank and access to the UV and other treatment stages, then size production around repeated collections.
