Purpose
Precision You Can Rely On—Flow Cells Built for Compliance and Confidence
In USP Apparatus 4 dissolution testing, precision isn’t optional—it’s everything. Starna’s Dissolution Flow Cells deliver the clarity, path length accuracy, and rugged performance needed for real-time UV-Vis monitoring in high-stakes pharmaceutical environments.
Description and Discussion
Engineered for Reliability. Proven in Regulated Labs.
These are more than cuvettes—they’re purpose-built analytical tools designed for continuous, contamination-free performance. Each cell is manufactured through direct heat fusion, eliminating adhesives and potential leachable compounds. The result is a monolithic quartz structure with superior optical clarity, chemical inertness, and thermal stability.
Every unit is pressure-tested beyond 5 bar and laser-engraved with a unique serial number and verified path length—so you get rock-solid performance and full traceability, batch after batch. Thanks to sub-micron path length accuracy (±0.2 µm) verified by interference spectrometry, you can trust your results in both routine QC and advanced R&D.
Designed for laminar flow and reduced bubble retention, these flow cells are optimized for high-throughput workflows and automated real-time drug release analysis. With a wide range of geometries—including long, wide, medium, and sub-micro apertures—they support virtually any dissolution protocol with minimal sample loss and maximum reproducibility.
Whether you’re building IVIVC models or releasing product to market, Starna Dissolution Flow Cells keep your data flowing—cleanly, accurately, and compliantly.
