Purpose
Starna’s dissolution flow cells are engineered for continuous operation.
They combine fully fused quartz flow paths, precision-machined enclosures, and optimised internal geometries to support smooth laminar flow, minimise bubble retention, and provide reliable sealing. This ensures consistent, traceable performance for pharmaceutical dissolution testing.
Description and Discussion
Engineered for Reliability. Proven in Regulated Labs..
Purpose‑built dissolution flow cells are designed for continuous, contamination‑free operation in regulated analytical environments, incorporating a metal‑jacketed design for added durability.
Each flow cell features a fully fused quartz sample chamber, manufactured by direct heat fusion without adhesives, eliminating potential leachables within the optical path. The quartz cell body is precision-mounted within a machined metal jacket, providing mechanical strength, dimensional stability, and secure integration with screw-in fittings.
All cells are pressure-tested beyond 5 bar after final assembly and laser-engraved with a unique serial number and verified pathlength, ensuring full traceability and consistent performance across batches.
For short pathlengths, sub-micron pathlength accuracy (±0.2 µm) is verified using interference spectrometry, providing confidence in both routine QC and advanced R&D applications.
Engineered inlet and outlet geometry promotes smooth, laminar flow and reduced bubble retention, supporting high-throughput dissolution testing and continuous, automated drug release analysis.
A wide range of aperture geometries, including long, wide, medium, micro and sub‑micro, supports multiple dissolution protocols while minimising sample loss and achieving consistent, reproducible results.
Suitable for research, development, and routine analytical testing, Starna Dissolution Flow Cells provide reliable, traceable optical measurements.
