Usage Guide of Fused Quartz UV Cuvette with PTFE Stopper
Правильное обращение
- Всегда берите кюветы за неоптические стороны (обычно за матовые или ребристые поверхности).
- Avoid touching the optical windows as fingerprints affect light transmission
- When inserting the PTFE stopper, apply gentle pressure with a slight twisting motion
- Store in protective cases when not in use to prevent scratches
- Never drop or apply excessive force to the cuvette
Clean Method
- Empty the cuvette immediately after use
- Rinse with an appropriate solvent compatible with your sample (often distilled water, ethanol, or acetone)
- For stubborn residues, soak in a suitable cleaning solution (2% Hellmanex III or similar laboratory detergent)
- Rinse thoroughly with distilled water
- For final cleaning, rinse with spectroscopic grade solvent
- Air dry or use filtered compressed air (never use paper towels on optical surfaces)
- Inspect optical surfaces against light to ensure they are clean and free of streaks
Загрузка образцов
- Fill to the recommended volume (typically 2/3 of the cuvette height)
- Ensure the liquid level is above the light path
- Avoid bubbles by gently tapping the cuvette or using a micropipette
- Secure the PTFE stopper to prevent evaporation during measurement
- For viscous samples, allow time for the sample to settle before measurement
Storage and Maintenance
- Store clean, dry cuvettes in their original protective case
- Keep PTFE stoppers with their matching cuvettes
- Periodically inspect for scratches or damage to optical surfaces
- For long-term storage, ensure cuvettes are completely dry
- Avoid storing near corrosive chemicals or in areas with temperature extremes
· Special holders may be required for non-standard path lengths
· PTFE stoppers are resistant to most laboratory chemicals
· Not recommended for use with hydrofluoric acid (HF)
· Maximum operating temperature: 1100°C for quartz, 260°C for PTFE stopper

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
Q: What is the temperature range for Fused Quartz UV Cuvette with PTFE stopper?
A: The quartz material can withstand temperatures up to 1100°C, but the PTFE stopper limits the practical temperature range to approximately 260°C (the maximum continuous use temperature for PTFE). For high-temperature applications, alternative sealing options can be discussed.
Q: Why use a Fused Quartz UV Cuvette with PTFE stopper instead of glass cuvettes?
A: Fused quartz provides superior UV light transmission down to 200nm, while standard glass absorbs UV light below 320nm. This makes quartz cuvettes essential for UV spectroscopy applications. The PTFE stopper offers better chemical resistance than plastic or glass stoppers, particularly with organic solvents and corrosive solutions.
Q: What is the wavelength range for Fused Quartz UV Cuvette with PTFE stopper?
A: TOQUARTZ® fused quartz UV cuvettes offer excellent transmission across a wide spectral range from 200nm (deep UV) to 2500nm (near infrared), making them versatile for various spectroscopic techniques including UV-Vis absorption, fluorescence, and some NIR applications.
Q: How do I clean a Fused Quartz UV Cuvette with PTFE stopper?
A: Clean immediately after use by rinsing with an appropriate solvent (water, ethanol, or acetone). For stubborn residues, soak in 2% laboratory detergent solution. Rinse thoroughly with distilled water followed by spectroscopic grade solvent. Air dry or use filtered compressed air. Never use paper towels on optical surfaces as they can cause scratches.
Q: What is the absorbance range of a Fused Quartz UV Cuvette with PTFE stopper?
A: TOQUARTZ® cuvettes provide accurate measurements across an absorbance range of approximately 0-3 AU (absorbance units), depending on your instrument specifications. The quartz material itself contributes minimal background absorbance in the UV-Visible range.
