Purpose
Precision Meets Purity With Full Quartz Construction High Purity Threaded Flow Cells—For Sterile, Accurate, and Compliant Pharmaceutical Analysis
When your lab demands more than just accuracy—when it needs sterility, chemical resilience, and uncompromising reliability—Starna’s High-Purity Threaded Quartz Flow Cells deliver. Engineered specifically for pharmaceutical dissolution testing and high-performance UV-Vis spectrophotometry, these premium flow cells are designed for environments where cleanliness, reproducibility, and traceability are non-negotiable.
Description and Discussion
Built Entirely from Quartz. Engineered for the Demands of Pharma.
Starna’s Threaded Quartz Flow Cells are crafted from a single material—high-purity synthetic quartz—right down to the threaded fittings. Unlike composite or PTFE-based flow cells, these are fused entirely from precision quartz components using high-temperature fusion bonding. The result? A monolithic structure with exceptional chemical resistance, thermal stability, and long-term durability, even under repeated sterilisation or autoclaving.
Why It Matters:
In high-throughput, highly regulated pharmaceutical environments, hybrid materials can compromise sterility or introduce inconsistencies. Starna’s full-quartz construction supports contamination-free workflows, withstands aggressive solvents and elevated temperatures, and maintains optical clarity where it matters most.
A New Benchmark in Flowcell Precision:
Each unit is engineered with sub-micron path length accuracy—verified within ±0.2 µm using interference spectrometry. That level of precision ensures consistent absorbance readings, essential for dissolution testing, real-time monitoring, and IVIVC studies.
Traceability and Compliance Baked In:
Every threaded quartz flow cell is pressure-tested to withstand over 5 bar, laser-engraved with a unique serial number, and manufactured to meet USP, Ph. Eur., and JP standards. This level of traceability supports regulatory compliance and eliminates uncertainty from your data pipeline.
Designed for Integration—Ready for Automation:
Compatible with USP Apparatus 4 and leading automated dissolution systems, Starna’s threaded flow cells slot into your workflow effortlessly, supporting seamless integration across instruments, software, and validation protocols.
