510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Purifier, Water (Absorption, Deionization, Membrane Filter, Reverse Osmosis)
Clinical Chemistry
The Purifier, Water (Absorption, Deionization, Membrane Filter, Reverse Osmosis) is a clinical laboratory device used to purify water to the quality required for reagent preparation and instrument use in clinical chemistry testing, employing one or more purification methods including absorption, ion exchange deionization, membrane filtration, or reverse osmosis. This device is FDA Class 1, the lowest risk category, requiring only general controls and no premarket notification. It carries product code JRS and is regulated under 21 CFR 862.2050, within the Clinical Chemistry medical specialty. This device is GMP exempt.
No 510(k) clearances found for "JRS". Try a different K-number, product code, or device name.
What is a Predicate Device?
A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
