K844188 is an FDA 510(k) clearance for the CORNING CALCIUM PH ANALYZER 634. Classified as Electrode, Ion Specific, Calcium (product code JFP), Class II - Special Controls.

Submitted by Corning Medical & Scientific (Medfield, US). The FDA issued a Cleared decision on February 4, 1985 after a review of 101 days - within the typical 510(k) review window.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1145 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
