TOQUARTZ® Solving Laboratory Challenges with Black Wall Quartz Micro Cuvettes

Quartz Micro Cuvette with Black Walls for DNA/RNA Quantification

Life science laboratories frequently work with precious nucleic acid samples where volume conservation is critical. Traditional cuvettes require substantial sample volumes (1-3ml), leading to waste of valuable material. Additionally, fluorescence-based quantification methods are hampered by stray light and background interference.

Principais vantagens

  • Minimized Sample Volume Loss
    Only 50μl sample required vs. 1–3ml in standard cuvettes, reducing nucleic acid waste by over 95%.
  • Stray Light Suppression Efficiency
    Black walls reduce background interference by 87%, improving fluorescence signal-to-noise ratio.
  • Precisão consistente do caminho óptico
    10.00mm ±0.05mm path length ensures <2% deviation in nucleic acid concentration readings.

Solução TOQUARTZ

A molecular biology lab in Heidelberg, Germany, reported inconsistent DNA quantification using standard 1ml cuvettes due to sample scarcity and high background noise. After switching to TOQUARTZ® 50μl black wall micro cuvettes, they achieved a 92% reduction in sample usage and a 1.8× improvement in fluorescence signal clarity. This enabled accurate quantification of DNA at concentrations as low as 0.3ng/μl, critical for their low-yield extraction workflows.

Quartz Micro Cuvette with Black Walls for Trace Analysis in Environmental Samples

Environmental testing laboratories must detect trace contaminants in water and soil extracts with high sensitivity. Conventional spectrophotometric methods struggle with sample-limited analyses and suffer from optical interference when measuring fluorescent compounds at parts-per-billion levels.

Principais vantagens

  • Enhanced Detection at ppb Levels
    Black wall design improves fluorescence detection sensitivity by 1.6× for analytes below 10ppb.
  • Reduced Optical Interference
    Stray light suppression exceeds 90%, critical for detecting PAHs and heavy metals in complex matrices.
  • Low Volume Compatibility
    Supports 50–300μl sample volumes, ideal for limited-volume soil and water extracts.

Solução TOQUARTZ

An environmental testing lab in Ontario, Canada, faced challenges detecting trace polycyclic aromatic hydrocarbons (PAHs) in river water due to high background fluorescence. Using TOQUARTZ® 100μl black wall cuvettes, they reduced optical noise by 21% and achieved consistent detection of benzo pyrene at 4.7ppb. This allowed them to meet regulatory reporting thresholds without increasing sample volume or processing time.

Quartz Micro Cuvette with Black Walls for Pharmaceutical Formulation Analysis

Pharmaceutical research requires precise analysis of API (Active Pharmaceutical Ingredient) concentrations in various formulations. Limited sample availability during early-stage development and interference from excipients create significant analytical challenges. Accurate spectroscopic measurements are essential for quality control and formulation optimization.

Principais vantagens

  • API Conservation in Early R&D
    Requires only 100μl per test, reducing API consumption by up to 80% during formulation screening.
  • Excipient Interference Mitigation
    Black walls block lateral light scatter, improving accuracy in complex excipient matrices.
  • Precision Path Length Control
    ±0.05mm tolerance ensures <1.5% deviation in absorbance-based API concentration assays.

Solução TOQUARTZ

A pharmaceutical R&D center in Osaka, Japan, struggled with accurate UV absorbance readings of early-stage API formulations due to excipient interference and limited sample availability. After adopting TOQUARTZ® 100μl black wall cuvettes, they reduced API usage per test from 500μl to 100μl and improved measurement repeatability by 93%. This enabled faster iteration of formulation batches while maintaining QC compliance.

Usage Guide of Quartz Micro Cuvette with Black Walls and Black Caps

Proper handling and maintenance of quartz micro cuvettes with black walls ensures optimal performance and extends their service life. Follow these guidelines to maximize measurement accuracy and product longevity.

Proper Handling Procedures

  • Always handle cuvettes by the top or opaque surfaces to avoid fingerprints on optical windows.
  • Fill cuvettes using micropipettes, taking care not to scratch the interior surfaces.
  • For most accurate results, ensure sample fills to the recommended volume mark without air bubbles.
  • Always use the provided caps to prevent sample evaporation during measurement.

Instruções de limpeza

  • Enxágue imediatamente após o uso com o solvente apropriado compatível com sua amostra.
  • For thorough cleaning, use 2% Hellmanex III solution, followed by thorough rinsing with ultrapure water.
  • For stubborn residues, soak in 5% HCl solution for 30 minutes (avoid using HF, which can etch quartz).
  • Dry with clean, compressed air or nitrogen gas. Never use paper towels on optical surfaces.

Práticas recomendadas de medição

  • Always use the same orientation in the instrument for consistency between measurements.
  • For fluorescence measurements, ensure the excitation beam passes through the clear windows, not the black walls.
  • Allow temperature-sensitive samples to equilibrate to room temperature before measurement.
  • Regularly check for scratches or damage that could affect optical performance.

Recomendações de armazenamento

  • Store clean, dry cuvettes in their original protective case or in a dust-free container.
  • Keep cuvettes away from abrasive surfaces that could scratch the optical windows.
  • Avoid prolonged exposure to strong UV light when not in use.

PERGUNTAS FREQUENTES

Q: Will the black walls of the Quartz Micro Cuvette with Black Walls and Black Caps affect UV-Vis transmission?

A: No, the optical windows remain transparent quartz; only the side walls are black-coated, ensuring full UV-Vis transmission (200–2500nm) through the measurement path.

A: The black coating is chemically bonded and resistant to most solvents, but abrasive cleaning or exposure to HF can damage it. Use non-abrasive cleaning methods only.

A: The black cap prevents ambient light from entering the cuvette from the top, reducing background noise and improving signal-to-noise ratio in fluorescence detection.

A: Yes, they follow the standard 12.5mm × 12.5mm × 45mm external dimensions and fit most commercial instruments with 10mm path length holders.

A: Variations may result from improper orientation, cap misalignment, or inconsistent sample volume. Always align the optical windows correctly and fill to the recommended volume.
