TOQUARTZ® Solving Challenges in Spectroscopic Analysis with Quartz Flow Cell Counting Cuvettes

Quartz Flow Cell Counting Cuvette in Hematology and Biochemistry Analyzers

Automated hematology and biochemistry analyzers run thousands of assays each day and rely on precise light transmission through small-volume samples. If cuvettes lose clarity or fail under chemical exposure, results can drift outside acceptable limits and require costly retesting. Reagent residues often corrode plastic chambers, shortening their usable life and disrupting workflow. Laboratories face both higher operating costs and longer downtime when measurement stability cannot be maintained.

Key Advantages

  • Low-volume chamber efficiency
    + Handles as little as 10 µL per assay, reducing reagent consumption by up to 25% compared to conventional cuvettes.
  • Corrosion-resistant flow path
    + Maintains optical clarity after exposure to >500 cycles of blood reagents without window etching or clouding.
  • Stable transmission consistency
    + Delivers ≤0.3% signal deviation across 24-hour continuous analyzer operation, reducing drift in assay results.
Find My Solution

TOQUARTZ® solution

A European clinical lab reported that plastic cuvettes corroded after 6 months, raising retest rates by nearly 12% and adding €15,000 in reagent costs annually. After switching to TOQUARTZ® Quartz Flow Cell Counting Cuvette, the lab maintained stable operation for over a year without performance loss. Retest rates dropped below 2%, and throughput increased by 18%, directly lowering analyzer downtime and cost per assay.

Quartz Flow Cell Counting Cuvette in Inline Chromatography Detection

Chromatography instruments demand consistent optical pathways to monitor analyte peaks in real time. Even minor leaks or optical misalignment in the flow cell can distort peak shapes, reducing data accuracy and reliability. High-pressure operation puts stress on standard flow chambers, leading to seal failures or clouded windows that affect spectral clarity. Analytical labs require durable cuvettes that integrate seamlessly with tubing systems to maintain throughput and reduce instrument downtime.

Key Advantages

  • Leak-proof M6 integration
    + Rated to 5 bar pressure, eliminating peak distortion caused by micro-leaks in high-performance chromatography systems.
  • Optical alignment stability
    + Window polishing tolerance supports <0.3% deviation, maintaining accurate retention time across long analytical runs.
  • High-pressure endurance
    + Withstands repeated injections in HPLC setups for >10,000 cycles without connector failure or window cracking.
Find My Solution

TOQUARTZ® solution

A US pharmaceutical QC lab experienced inconsistent chromatogram peaks due to seal failures in polymer cells, causing 1 in 20 runs to be invalidated. With TOQUARTZ® Quartz Flow Cell Counting Cuvette, the lab achieved 100% run completion over 3 months of continuous HPLC testing. Downtime decreased by 22 hours per month, and validation data consistency improved, supporting FDA audit compliance without additional corrective testing.

Quartz Flow Cell Counting Cuvette in Fuel and Lubricant Quality Testing

Petrochemical testing facilities measure clarity and particulate levels in fuels and lubricants under continuous flow conditions. Polymer-based cuvettes frequently degrade when exposed to hydrocarbons, causing spectral interference and forcing repeat measurements. High-viscosity samples also place stress on cell chambers, leading to premature cracking or seal failures. Inconsistent results raise the risk of non-compliance with ASTM or ISO testing standards, which directly impacts production timelines and customer trust.

Key Advantages

  • Hydrocarbon-resistant quartz walls
    + Maintains >95% optical clarity after 90 days of continuous diesel fuel testing, outperforming polymer cells that degrade within 2 weeks.
  • Viscosity-tolerant chamber design
    + Flow geometry resists cracking under exposure to lubricants with viscosity up to 800 cP.
  • Standards-compliant durability
    + Supports long-term use under ASTM D1500 and ISO 2049 testing conditions with no sample leakage.
Find My Solution

TOQUARTZ® solution

A Middle Eastern refinery lab using polymer cuvettes faced frequent spectral interference after 200 hours of diesel analysis, leading to 15% repeat testing rates and significant compliance risks. After adopting TOQUARTZ® Quartz Flow Cell Counting Cuvette, repeat tests dropped to under 3%, and each cuvette lasted for more than 1,000 test hours without structural degradation. This improved regulatory compliance and cut downtime by nearly 40%, directly reducing per-sample testing costs.

Product Usage Guideline

The Quartz Flow Cell Counting Cuvette requires proper handling to ensure long service life and reliable results. This guide covers daily operation, cleaning steps, storage methods, and troubleshooting practices for laboratories and industrial users.

Operating Instructions

  • Fill the cuvette slowly to avoid bubble formation in the flow chamber.
  • Ensure stainless-steel tube connections are tightened securely before measurement.
  • Use compatible instruments within the optical range of 190–2500 nm.
  • Run initial calibration checks to confirm ≤0.3% transmission deviation.

Cleaning and Maintenance

  • Rinse with deionized water immediately after use to prevent residue buildup.
  • For persistent stains, soak in neutral detergent at 40–50 °C before rinsing.
  • Avoid abrasive brushes that may scratch optical windows.
  • Dry with filtered air or lint-free tissues to maintain window clarity.

Storage Recommendations

  • Store cuvettes in a dust-free, dry cabinet with controlled humidity.
  • Keep optical windows protected with covers to prevent scratches.
  • Avoid direct sunlight exposure that can alter material stability over time.
  • Separate used and unused cuvettes to reduce cross-contamination risks.

Troubleshooting Guide

  • If signal drift occurs, check for micro-bubbles in the flow path and refill.
  • Leakage around the tube indicates loose stainless-steel fittings or worn seals.
  • Cloudy readings often result from residue; repeat cleaning with DI water and detergent.
  • If deviation exceeds 0.3%, replace the cuvette to restore measurement accuracy.
