Applied Physics Water Technologies
High-flow point-of-use polishing for pretreated laboratory water
Start with the required water grade and application, then size around feedwater quality, daily demand, peak dispense rate, storage, distribution distance and the number of points of use. ELGA PURELAB, CENTRA and MEDICA are third-party ELGA LabWater systems supplied through Applied Physics; MODULAB is presented separately as a high-flow polishing platform.
Ultrapure point-of-use · PURELAB Chorus / Flex
Use the PURELAB family when the laboratory needs a point-of-use ultrapure-water workflow. Select the exact model from feedwater, daily volume, TOC and application requirements.
PURELAB Chorus GuideCentral distribution · CENTRA
CENTRA R200 integrates purification, storage and distribution for multi-point loops. Standard R200 and high-flow variants have different delivery-flow specifications.
CENTRA R200Clinical analyzers · MEDICA
MEDICA Pro is designed around CLRW supply to single or multiple clinical diagnostic analyzers, with production configurations from 30 to 120 L/h.
MEDICA Pro R120High-flow polishing · MODULAB
MODULAB High Flow polishes RO or DI feedwater at the point of use, with published flow from 2 to 14 L/min and application-specific cartridge configurations.

Technical FAQ
Questions engineers and validation teams ask
How do I choose between Type I, Type II and Type III laboratory water?
Choose the water grade from the application and instrument requirements first, then size the system around feedwater quality, daily volume, peak dispense rate, storage and distribution needs. Type I is ultrapure water for the most sensitive applications; Type II and Type III support progressively less demanding laboratory uses and pretreatment workflows.
Does Applied Physics manufacture ELGA PURELAB, CENTRA or MEDICA systems?
No. ELGA LabWater is the product brand for PURELAB, CENTRA and MEDICA systems. Applied Physics Water Technologies supplies ELGA products for customers in the United States and Canada and provides product-selection and quotation support.
When is a centralized water system preferable to a point-of-use system?
A centralized system can be preferable when multiple laboratories or points of use need a shared purified-water loop. Point-of-use systems are often better when one laboratory or instrument needs a localized supply. Required flow, water grade, redundancy and distribution distance should drive the selection.
