TOQUARTZ® Solutions for Precision Spectroscopy Challenges with Quartz Cuvette with Funnel Top

Quartz Cuvette with Funnel Top in High-Throughput Drug Screening Labs

In pharmaceutical R&D, high-throughput screening (HTS) platforms process thousands of compounds daily using fluorescence-based assays. Manual or robotic pipetting into standard cuvettes often leads to sample spillage, cross-contamination, and inconsistent volumes—especially when using viscous or volatile solvents. These issues compromise assay reproducibility and increase false-positive rates.

Ключевые преимущества

  • Minimized Loading Time in HTS Pipetting
    Funnel top reduces robotic pipetting alignment time by 1.2 seconds per well, saving ~20 minutes per 1,000 samples.
  • Reduced Sample Loss with Viscous Compounds
    Funnel geometry decreases overflow incidents by 87% when dispensing DMSO-based solutions.
  • Improved Volume Consistency Across Wells
    Standard deviation in loaded volume reduced from ±4.3μL to ±1.1μL in 96-well fluorescence assays.

раствор TOQUARTZ®

A US-based pharmaceutical CRO using a Tecan Fluent HTS system faced 11% assay variability due to pipetting misalignment and overflow with viscous solvents. After switching to TOQUARTZ® funnel cuvettes, sample loading errors dropped by 89%, and daily throughput increased by 16%, enabling 1,200+ compounds/day with consistent fluorescence readouts.

Quartz Cuvette with Funnel Top for Micro-Volume Fluorescence in Genetic Diagnostics

Genetic testing labs often work with precious biological samples such as DNA/RNA extracts or PCR products in volumes as low as 50μL. Standard cuvettes with narrow openings make it difficult to load such small volumes without loss or bubble formation, which can distort fluorescence readings and waste irreplaceable samples.

Ключевые преимущества

  • Precision Loading of ≤50μL Samples
    Funnel inlet diameter of 9mm enables accurate pipetting of 20–50μL DNA/RNA samples with <2% loss.
  • Bubble-Free Pipetting for PCR Fluids
    Tapered inner wall reduces bubble formation by 92% compared to flat-top cuvettes.
  • Preservation of Rare Genetic Material
    Sample recovery rate improved from 94.5% to 98.8% in low-volume fluorescence assays.

раствор TOQUARTZ®

A German molecular diagnostics lab performing qPCR-based fluorescence detection on 30μL DNA eluates reported 14% sample loss due to bubble formation and misloading. After adopting TOQUARTZ® funnel cuvettes, sample loss dropped to under 2%, and retest rates fell by 78%, saving €6,400/month in reagents and technician time.

Quartz Cuvette with Funnel Top in Biohazardous Fluorescence Assays

In biosafety level 2/3 labs, fluorescence assays are used to detect pathogens like SARS-CoV-2 or E. coli. Operators must minimize exposure and avoid spills when handling infectious samples. Traditional cuvettes with narrow necks increase the risk of splash-back or misloading, posing safety hazards and requiring frequent decontamination.

Ключевые преимущества

  • Splash-Free Loading in BSL-2/3 Cabinets
    Funnel design reduced splash-back incidents by 93% during manual pipetting of infectious samples.
  • Glove-Compatible Handling for PPE Users
    Wide opening allows accurate pipetting even with 2-layer nitrile gloves under biosafety hoods.
  • Герметичное уплотнение для летучих следов
    Предотвращает испарение остатков красителя на основе этанола в течение 4 часов при 25°C.

Рекомендации по использованию и уходу

Proper handling and maintenance of TOQUARTZ® Quartz Cuvettes with Funnel Top will ensure optimal performance and extended service life. Follow these recommendations for best results in your spectroscopic applications.

Handling and Loading Samples

  • Always wear powder-free gloves when handling cuvettes to prevent fingerprints and contamination.
  • Use the funnel top to carefully introduce samples, avoiding rapid pouring that might create bubbles.
  • Fill to approximately 3/4 of the cuvette height for optimal measurement results.
  • Ensure the optical windows (clear sides) are clean and free from fingerprints before measurement.

Процедуры очистки

  • Rinse immediately after use with appropriate solvents (typically distilled water followed by acetone or ethanol).
  • For persistent residues, soak in 10% laboratory-grade detergent solution for 30 minutes.
  • Avoid abrasive materials that could scratch optical surfaces.
  • For biological samples, a solution of 2% sodium hypochlorite may be used, followed by thorough rinsing.
  • Final rinse should always be with high-purity solvent and allowed to air dry in a dust-free environment.

Рекомендации по хранению

  • Store clean, dry cuvettes in their original protective packaging or dedicated cuvette holders.
  • Keep in a dust-free cabinet away from potential physical damage.
  • Avoid contact with HF (hydrofluoric acid), which can etch quartz surfaces.
  • Periodically inspect for chips, cracks, or surface contamination before use.

Температурные соображения

  • Allow cuvettes to gradually reach thermal equilibrium when transitioning between temperature extremes.
  • For high-temperature applications, heat and cool at rates not exceeding 5°C per minute to prevent thermal shock.
  • When using at elevated temperatures, ensure uniform heating to prevent localized stress.

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

Q: How does the funnel top improve pipetting accuracy in fluorescence workflows?

A: The funnel top of the Quartz Cuvette with Funnel Top guides the pipette tip into the center of the cuvette, reducing misalignment. This minimizes sample spillage and ensures consistent volume delivery. It is particularly beneficial when working with viscous or volatile solvents. Accurate pipetting improves reproducibility in fluorescence intensity measurements.

A: Yes, the Quartz Cuvette with Funnel Top is designed with automation in mind. Its consistent dimensions and wide funnel opening support robotic pipetting systems. The cuvette can be integrated into fluorescence plate readers or custom holders. This reduces manual handling and increases throughput in high-volume labs.

A: The tapered funnel design of the Quartz Cuvette with Funnel Top directs liquid smoothly into the chamber. This reduces turbulence and prevents air entrapment during pipetting. Air bubbles can distort fluorescence readings by scattering light or blocking the optical path. The funnel minimizes this risk, especially in micro-volume applications.

A: The Quartz Cuvette with Funnel Top offers four-sided optical transparency, allowing flexible excitation and emission configurations. Its high-purity quartz ensures minimal background fluorescence and excellent UV transmission. The funnel top design enables precise sample loading without introducing bubbles. This is especially useful in sensitive fluorescence-based quantification.

A: The funnel top of the Quartz Cuvette with Funnel Top can be tailored in diameter, angle, and lip design. This ensures compatibility with specific pipette tips or robotic arms. Anti-splash and anti-bubble features can also be integrated. Customization improves workflow efficiency and reduces sample handling errors in fluorescence labs.
