Laboratory Ultrapure Water System – ST-LPW28 Series produces RO and high-resistivity water in a tall laboratory cabinet for regular preparation. It supplies a defined collection point with online water-quality indication and separate criteria for particles, microbes and heavy metals.
The RO conductivity range is wider than in the closely related higher-rejection options, while the final resistivity requirement remains separately stated. Those different stages should be compared independently when deciding which outlet serves each laboratory task.
MODELS AND DIMENSIONS

| ST-LPW28-060 | 60 L/h at 25°C | supplied with 17 gal pressure tank |
| ST-LPW28-100 | 100 L/h at 25°C | supplied with 28 gal pressure tank |
Production-rate ratings are stated at the temperature shown in the table.
MODEL DIFFERENCES
Which configuration fits the task
ST-LPW28-060
At 60 L/h, production and tank size both increase, with a 17 gal tank providing more buffer for repeated draws.
ST-LPW28-100
The 100 L/h and 28 gal combination is the largest option for heavier sessions, increasing both production recovery and nominal storage.
FEATURES AND BENEFITS
How it helps
Stage-specific water quality
The RO and final-water specifications describe different points in the treatment process.
Three output duties
The capacity choices change the rate at which preparation water is replenished while retaining the common cabinet dimensions.
APPLICATIONS
Where it is used
Shared laboratory water collection
Place a monitored water point near repeated preparation and rinsing tasks, with each outlet selected for the task’s required water quality.
SYSTEM SELECTION
Select the outlet and tank pairing
Two preparation duties
Check the RO quality required for routine work separately from the final-water criteria used for more sensitive preparation.
Collection reserve
Choose the matched output and pressure-tank combination for batch volume and refill time, with space for the complete floor-standing supply.
