Purpose
Precision in Every Well. Performance You Can Trust.
Whether you're screening pharmaceuticals or running fluorescence assays, Starna’s Quartz 96 Well Plates deliver unmatched optical clarity, dimensional accuracy, and rugged reliability. For labs that need reproducible results and need them fast, this is the gold standard.
Description and Discussion
Engineered for Accuracy. Built for High-Throughput Labs.
Every aspect of Starna’s Quartz 96 Well Plates is designed to support precision-driven spectroscopic workflows. Manufactured to ANSI/SLAS standards, they’re ready for automation straight out of the box, minimising manual handling and human error.
The ultra-flat quartz well bottoms eliminate light scatter and signal distortion. That means clearer baselines and sharper peaks in UV-VIS, fluorescence, and even IR applications. With an wide optical transmission range from 170–2500 nm and negligible autofluorescence, you can push your analysis deeper and trust the results every time.
Durable? Absolutely.
These plates are made from 99.99% high-purity synthetic quartz and can handle aggressive solvents, repeated sterilisation, and temperatures up to 1100°C. Forget frequent replacements— Starna’s Quartz 96 Well Plates are a long-term investment in consistency.
Built for Automated Excellence.
Perfect dimensional tolerances, chemical resistance, and automation-ready design make these plates a seamless fit in high-throughput labs where speed and reproducibility are key.

Purpose
These totally quartz construction flow cells are designed for Tablet Dissolution applications and, at the same time, facilitate aggressive cleaning or autoclaving if necessary to avoid cross-contamination between different types of samples.
The design of the flow cell, with an integral threaded quartz top, allows complete immersion in solvent or strong acid cleaning solutions.
Engineered specifically for pharmaceutical dissolution testing and high-performance UV-Vis spectrophotometry, these premium total quartz flow cells are designed for environments where cleanliness, reproducibility, and traceability are non-negotiable.
Description and Discussion
Constructed entirely from quartz and engineered for the demands of stringent pharmaceutical protocols
The Starna Threaded Quartz Flow Cells are manufactured from high-purity synthetic quartz, including the quartz threaded tops. The cells are assembled from precision parts that are fully fused together to form 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, Starna’s fully 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 cell with path lengths of 2 mm or less is engineered to sub-micron path-length accuracy, verified within ±0.2 µm using interference spectrometry. That level of precision ensures consistent absorbance readings, which are essential for dissolution testing, real-time monitoring, and IVIVC studies. Path lengths of 5 mm or more are accurate to the micron level, according to the published specifications.
Traceability and Compliance:
Every threaded quartz flow cell is pressure-tested to 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 in customer data.
Designed for Integration—Ready for Automation:
Compatible with USP Apparatus 4 and leading automated dissolution systems, the Starna threaded flow cells are compatible with all tablet flow-cell apparatus, supporting seamless integration across instruments, software, and validation protocols.

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 ensure smooth laminar flow, minimise bubble retention, and provide reliable sealing. This ensures consistent, traceable performance in pharmaceutical dissolution testing.
Description and Discussion
Engineered for Reliability. Proven in Regulated Laboratories
Purpose‑built dissolution flow cells are designed for continuous, contamination‑free operation in regulated analytical environments and feature a metal‑jacketed construction for added durability.
Each flow cell features a fully fused quartz sample chamber, manufactured by direct heat fusion without adhesives. 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 to 5 bar after final assembly, laser-engraved with a unique serial number and verified pathlength and verified for traceability and consistent performance across batches.
For short pathlengths of 2 mm or less, sub-micron pathlength accuracy (±0.2 µm) is verified by interference spectrometry, providing confidence in both routine QC and advanced R&D applications.
Engineered inlet and outlet geometry promotes smooth, laminar flow and reduces 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, minimises sample loss and delivers consistent, reproducible results.
Suitable for research, development, and routine analytical testing, Starna Dissolution Flow Cells deliver reliable, traceable optical measurements.
