TOQUARTZ® Solving Critical Challenges in Spectroscopy Applications with Frosted Quartz Micro Cuvette with Lid

Trace-Level Fluorescence Detection in Environmental Pollutant Monitoring Using Frosted Quartz Micro Cuvette with Lid

In environmental labs analyzing trace pollutants like PAHs or heavy metals via fluorescence spectroscopy, even minor stray light can distort low-intensity signals. Standard clear cuvettes often introduce background noise, especially in micro-volume setups, leading to false positives or poor detection limits.

Die wichtigsten Vorteile

  • Reduced Sidewall Reflection by 38.6%
    Frosted surface diffuses lateral light, lowering background signal in ppb-level fluorescence.
  • Improved Signal-to-Noise Ratio by 2.9×
    Enables detection of PAHs and heavy metals at <0.5 ppb with stable baselines.
  • Minimized False Positives in Micro-Volume Tests
    Suppresses optical noise in 350μl samples, reducing false detection events by 31%.
Meine Lösung finden

TOQUARTZ®-Lösung

An environmental testing lab in Poland struggled with inconsistent fluorescence readings when detecting benzo[a]pyrene at 0.3 ppb. Using standard clear cuvettes, background noise caused 22% false positive rates. After switching to TOQUARTZ® frosted quartz micro cuvettes, false positives dropped to 6%, and detection repeatability improved by 2.7× across 5 replicates.

Protein Aggregation Studies in Biopharmaceutical Formulation Using Frosted Quartz Micro Cuvette with Lid

Biopharma R&D teams often analyze protein aggregation via UV absorbance at 280nm. In micro-volume formats, light scatter from cuvette walls can mimic aggregation signals, leading to false interpretation of protein stability. Sample evaporation during thermal ramping further complicates results.

Die wichtigsten Vorteile

  • Scatter Reduction at 280nm by 41%
    Frosted walls eliminate wall-induced light scatter that mimics protein aggregation.
  • Evaporation Loss Reduced by 85%
    PTFE lid maintains sample volume during 60-minute thermal ramping cycles.
  • Improved A280 Consistency in 1ml Samples
    Liefert <1.2% absorbance deviation across 10 replicates in micro-volume assays.
Meine Lösung finden

TOQUARTZ®-Lösung

A biopharma R&D team in South Korea observed inconsistent A280 readings during thermal stress testing of monoclonal antibodies. Using clear cuvettes, aggregation was falsely indicated in 3 out of 10 samples. After adopting TOQUARTZ® frosted quartz micro cuvettes, false aggregation signals were eliminated, and absorbance deviation dropped from 3.8% to 0.9%, enabling reliable formulation screening.

DNA Quantification in Forensic Micro-Sample Analysis Using Frosted Quartz Micro Cuvette with Lid

Forensic labs often work with degraded or trace DNA samples. UV absorbance at 260nm requires high signal clarity, but standard cuvettes introduce optical noise in low-volume samples. Additionally, sample loss due to evaporation can compromise irreplaceable evidence.

Die wichtigsten Vorteile

  • Noise Suppression in 260nm UV Readings
    Frosted walls reduce optical interference, enhancing clarity in degraded DNA samples.
  • Sample Volume Retention >98%
    PTFE lid prevents evaporation during 30-minute quantification protocols.
  • Detection Sensitivity Improved by 2.4×
    Enables accurate quantification from as little as 5ng/μl DNA in 350μl volumes.
Meine Lösung finden

TOQUARTZ®-Lösung

A forensic lab in Ontario, Canada, faced challenges quantifying degraded DNA from 15-year-old evidence. Standard cuvettes introduced noise that masked low-concentration signals. After switching to TOQUARTZ® frosted quartz micro cuvettes, signal clarity improved significantly, enabling successful quantification at 5ng/μl with 96% confidence, and reducing sample reprocessing by 40%.

Richtige Handhabung

  • Always handle cuvettes by the frosted sides to avoid fingerprints on optical windows
  • Place on clean, soft surfaces when not in use
  • Avoid touching optical faces with bare hands
  • Use cuvette holders designed for 12.5mm × 12.5mm dimensions

Probe laden

  • Fill to appropriate volume using micropipettes
  • Avoid scratching inner walls with pipette tips
  • Ensure no air bubbles are present in the light path
  • Secure PTFE lid firmly but avoid over-tightening

Verfahren zur Reinigung

  • Sofort nach Gebrauch mit einem geeigneten Lösungsmittel (in der Regel deionisiertes Wasser) abspülen
  • For persistent residues, soak in 5% HCl or Hellmanex™ solution
  • Rinse thoroughly with ultrapure water
  • Dry with filtered compressed air or nitrogen
  • Avoid abrasive materials that could scratch optical surfaces

Empfehlungen zur Lagerung

  • In der Originalverpackung oder in speziellen Küvettenhaltern aufbewahren
  • In staubfreier Umgebung aufbewahren
  • Store with PTFE lid slightly loosened to prevent sticking
  • Avoid direct contact with other cuvettes or hard surfaces

FAQ

Q: Why does the Frosted Quartz Micro Cuvette with Lid have frosted sidewalls instead of fully transparent walls?

A: The frosted sidewalls in the Frosted Quartz Micro Cuvette with Lid are designed to suppress stray light and reduce internal reflections, which is critical for improving signal-to-noise ratio in micro-volume UV-VIS and fluorescence measurements.

A: No. The optical windows remain fully polished for accurate light transmission. The frosted areas are only on the sidewalls, outside the light path, and do not interfere with measurement accuracy.

A: The PTFE lid maintains a tight seal under temperature changes, reducing evaporation by over 85% during thermal ramping in protein or DNA stability studies.

A: No. The frosted walls are outside the optical path and do not interfere with baseline correction. In fact, they help stabilize the baseline by reducing stray light interference.

A: Yes. The frosted design enhances signal clarity at 260nm, and the lid prevents evaporation, making the Frosted Quartz Micro Cuvette with Lid ideal for forensic or trace DNA quantification.
