TOQUARTZ® Solving Challenges in Fluorescence Spectroscopy Analysis with Quartz fluorescence cuvette with lids

Quartz Fluorescence Cuvette with Lid for DNA/RNA Analysis

Molecular biology laboratories require precise fluorescence measurements for DNA and RNA quantification. Variations in measurements can lead to experimental errors and inconsistent results, especially when working with small sample volumes.

Key Advantages

  • Ultra-tight path length tolerance (±0.05mm)
    Ensures consistent excitation volume across replicates, reducing CV to <2% in qPCR assays.
  • Low-volume compatibility down to 100μL
    Minimizes reagent use while maintaining fluorescence signal integrity in micro-assays.
  • Four-side optical window alignment
    Enables dual-axis excitation/emission for high-sensitivity nucleic acid quantification.
Find My Solution

TOQUARTZ® solution

A genomics lab in Boston reported 8–12% signal deviation using generic cuvettes in DNA quantification. After switching to TOQUARTZ® cuvettes with ±0.05mm tolerance and 100μL compatibility, their inter-replicate CV dropped to 1.6%, improving qPCR reproducibility and reducing reagent waste by 35%. The lab now uses TOQUARTZ cuvettes as standard for all nucleic acid fluorescence workflows.

Quartz Fluorescence Cuvette with Lid for Protein Analysis

Protein analysis using fluorescence spectroscopy demands high sensitivity and stable measurement conditions. Many laboratories struggle with sample evaporation and concentration changes during longer experiments.

Key Advantages

  • PTFE-sealed lid with <0.5% evaporation rate over 24h
    Maintains protein concentration stability during long-term kinetic fluorescence assays.
  • Black masking option for stray light suppression
    Reduces background noise by 18%, enhancing signal-to-noise ratio in low-abundance protein detection.
  • Custom 20mm path length for low-concentration proteins
    Improves detection sensitivity by 2.3× compared to standard 10mm cuvettes.
Find My Solution

TOQUARTZ® solution

A German biotech firm faced 6% protein concentration drift in 12-hour fluorescence kinetics using open-top cuvettes. TOQUARTZ® sealed cuvettes reduced evaporation to <0.5%, maintaining sample integrity throughout the assay. With black-masked sides, background noise dropped by 18%, enabling detection of 0.2μg/mL BSA with 98% accuracy. This allowed the firm to validate protein stability protocols previously deemed unreliable.

Quartz Fluorescence Cuvette with Lid for Environmental Analysis

Environmental laboratories analyzing trace contaminants face challenges with sample contamination and maintaining detection limits. Traditional open cuvettes can compromise sample integrity and increase analysis variability.

Key Advantages

  • Sealed lid prevents airborne particulate contamination
    Reduces false positives in PAH detection by 22% in urban air quality monitoring.
  • Low-autofluorescence quartz (<0.002 AU at 300nm)
    Enables detection of trace-level contaminants down to 0.05 ppb with minimal background interference.
  • Anti-leaching PTFE cap certified for VOC testing
    Ensures no organic interference in volatile compound analysis over 48h storage.
Find My Solution

TOQUARTZ® solution

A Tokyo-based environmental lab struggled with inconsistent PAH readings due to sample contamination. Switching to TOQUARTZ® sealed cuvettes reduced airborne particle interference, improving detection repeatability by 27%. Low-autofluorescence quartz enabled reliable quantification of benzo[a]pyrene at 0.04 ppb. The lab now uses TOQUARTZ cuvettes for all trace organic pollutant fluorescence assays.

Usage and Care Guidelines

Proper handling and maintenance of your quartz fluorescence cuvettes will ensure optimal performance and extend their service life.

Handling Instructions

  • Always handle with gloves:
    Fingerprints can affect optical performance and measurement accuracy.
  • Hold by non-optical surfaces:
    Avoid touching the clear optical windows to prevent contamination.
  • Secure lid properly:
    Ensure the PTFE lid is securely in place to prevent evaporation and contamination.
  • Avoid rapid temperature changes:
    Gradual temperature transitions prevent thermal stress and potential damage.

Cleaning and Maintenance

  • Clean immediately after use:
    Prevents sample residue from drying and becoming difficult to remove.
  • Use appropriate solvents:
    Start with mild detergents, followed by distilled water. Use acetone or ethanol for stubborn residues.
  • Air dry or use lint-free cloth:
    Never use abrasive materials or paper towels, which can scratch the optical surfaces.
  • Store in protective case:
    When not in use, store cuvettes in their original packaging or a dedicated dust-free container.

Tips for Optimal Measurements

  • Ensure cuvette is properly oriented in the instrument with optical windows facing the light path.
  • Allow samples to reach room temperature before measurement to prevent condensation.
  • Use the same cuvette for all measurements in a series to maintain consistency.
  • Avoid air bubbles by gently tapping the cuvette before measurement.
  • Fill to the appropriate volume - usually 80-90% of capacity is optimal.
  • Establish a baseline with the same buffer or solvent used in your samples.
