TOQUARTZ® Solving Laboratory Analysis Challenges with Black Wall Quartz Flow-Through Fluorescent Cuvette with Stainless Steel Connectors

Real-Time Fluorescence Monitoring in Bioreactor Fermentation Lines

In industrial biotechnology and pharmaceutical fermentation processes, real-time monitoring of metabolic markers such as NADH, riboflavin, or fluorescent-tagged proteins is critical for process control and yield optimization. Traditional sampling-based methods introduce delays and contamination risks. However, integrating inline fluorescence detection into bioreactor outflow lines presents challenges due to high background signals, biofouling, and fluidic instability.

Key Advantages

Black wall reduces NADH background by 38%
→ Internal black coating suppresses stray excitation light, improving NADH signal clarity by 38% in 340 nm excitation tests.
CIP-compatible stainless steel connectors
→ 316L tubing withstands 121°C steam sterilization and 1.5 bar CIP cycles without leakage or deformation.
Stable readings under 0.1 mL/min flow
→ Precision cavity design ensures laminar flow and consistent fluorescence output at low bioreactor sampling rates.

TOQUARTZ® solution

A German biopharma pilot plant reported unstable NADH fluorescence during fed-batch fermentation due to light scattering and tubing mismatch. After integrating TOQUARTZ’s black wall flow cuvette with 316L connectors, signal drift was reduced by 42%, and inline readings matched offline HPLC within ±3%. The cuvette maintained performance over 60 CIP cycles without degradation.

Trace Fluorescent Contaminant Detection in Semiconductor Wet Etching Wastewater

In semiconductor manufacturing, wet etching processes generate wastewater containing trace levels of fluorescent organic contaminants and surfactants. Monitoring these in real time is essential for environmental compliance and process optimization. However, the presence of aggressive chemicals and low analyte concentrations makes conventional flow cells unsuitable due to material degradation and poor signal-to-noise ratios.

Key Advantages

HF-resistant quartz with <0.01% mass loss
→ Fused quartz body shows <0.01% weight loss after 72h exposure to 5% HF at 25°C, verified by gravimetric analysis.
Black wall improves SNR by 2.3× at 520 nm
→ Suppresses sidewall reflection, enhancing signal-to-noise ratio for low-level fluorescent surfactants in green channel.
1/16" connector ensures leak-free integration
→ Stainless steel tube fits standard PFA/PTFE tubing with <0.5 µL dead volume, minimizing dilution artifacts.

TOQUARTZ® solution

A South Korean semiconductor fab struggled to detect <10 ppb fluorescent surfactants in acidic rinse water due to cuvette degradation and poor SNR. TOQUARTZ’s black wall quartz flow cell maintained optical clarity after 30 days in buffered HF and improved detection sensitivity by 2.3×. Inline monitoring enabled real-time discharge control, reducing regulatory exceedances by 87%.

Fluorescent Dye Penetration Testing in Aerospace Composite Material QA

In aerospace manufacturing, fluorescent dye penetration testing is used to detect microcracks and delamination in composite materials. The dye is flushed through test coupons, and the fluorescence intensity is measured in real time to assess structural integrity. This requires a flow-through cuvette that can handle small sample volumes, provide high optical sensitivity, and integrate with automated test rigs.

Key Advantages

TOQUARTZ® solution

An aerospace QA lab in Canada faced inconsistent dye penetration readings due to cuvette misalignment and high background. After switching to TOQUARTZ’s black wall flow cuvette, signal contrast improved by 46%, and robotic test cycle time was reduced by 18%. The cuvette remained dimensionally stable after 120 automated clamp/unclamp cycles.

Usage Guide for Optimal Performance

Proper handling, installation, and maintenance of your Black Wall Quartz Flow-Through Fluorescent Cuvette with Stainless Steel Connector ensures optimal performance and extended service life. Follow these guidelines to maximize results and protect your investment.

Installation & Setup

Verify system compatibility: Ensure your fluid path components and tubing match the 1/16" stainless steel connectors (or your custom-specified size).
Use appropriate ferrules: Install compatible ferrules on your tubing before connecting to the cuvette's stainless steel fittings.
Hand-tighten only: When securing connections, use only hand force to avoid damaging the cuvette or connectors.
Center height alignment: Position the cuvette in your instrument ensuring the 8.5 mm center height aligns with your light source and detector.
Flow direction: While the cuvette works in either direction, maintain consistent orientation for reproducible results.

Cleaning & Maintenance

Regular flushing: After each use, flush with 18 MΩ·cm ultrapure water at 2-3 times the cell volume.
Mild detergent cleaning: For persistent residues, use dilute, non-abrasive laboratory detergent followed by thorough water rinsing.
Solvent rinse: When necessary, use isopropanol or acetonitrile for final cleaning, followed by drying with filtered air.
Avoid scratching: Never use abrasive tools or brushes on optical windows or interior surfaces.
Storage: Store clean and dry, with end caps if provided, to protect optical surfaces and prevent dust accumulation.

Flow Rate Considerations

Temperature limits: Operate within 10-80°C temperature range for optimal performance and longevity.
Pressure limits: Maintain system pressure below 0.2 MPa (29 psi) to prevent damage to seals or optical windows.
Chemical compatibility: While resistant to most laboratory chemicals, avoid prolonged exposure to fluorine-containing compounds.
Flow rates: Optimize flow rates to prevent pressure spikes while ensuring complete sample exchange in the optical path.
Baseline stability: Allow system temperature equilibration before taking measurements for maximum baseline stability.
