Usage Guide of Standard Quartz UV Cuvette with Lid
Cleaning and Maintenance
-
Rinse immediately after use
- Prevent sample residue buildup with appropriate solvent. -
Clean with compatible solvents
- For organic samples, use acetone, ethanol, or methanol. For aqueous solutions, use deionized water followed by ethanol. -
Avoid abrasive materials
- Never use paper towels or abrasive cleaners on optical surfaces. -
Dry properly
- Air dry in clean environment or use compressed air (oil-free). -
Store in protective case
- Keep in original packaging or dedicated cuvette holders.
Handling and Operation
-
Clean before first use
- Remove any manufacturing residues with spectroscopic-grade solvent. -
Hold by non-optical surfaces
- Avoid touching polished sides to prevent fingerprints and contamination. -
Fill properly
- For standard 10mm cuvettes, 3ml sample volume is optimal (approximately 3/4 full). -
Orient correctly
- Align polished sides perpendicular to the light path in your spectrophotometer. -
Secure lid properly
- Tighten gently to prevent sample evaporation and contamination.

FAQ
Q: Why use a Standard Quartz UV Cuvette with Lid instead of glass cuvettes?
A: Quartz cuvettes transmit light in the UV range (below 350nm) where glass cuvettes absorb radiation. This makes quartz essential for UV spectroscopy applications. The addition of a lid prevents sample evaporation, contamination, and provides safer handling of hazardous materials.
Q: What is the Standard Quartz UV Cuvette with Lid path length and why does it matter?
A: The path length is the distance light travels through the sample (typically 10mm in standard cuvettes). According to Beer-Lambert law, absorbance is directly proportional to path length, so different path lengths allow measurement of samples with varying concentrations. Shorter path lengths (0.5-5mm) are ideal for concentrated samples, while 10mm is standard for most applications.
Q: What is the wavelength range of Standard Quartz UV Cuvettes with Lid?
A: TOQUARTZ® Standard Quartz UV Cuvettes have a transmission range of 200-2500nm, covering ultraviolet, visible, and near-infrared regions. This makes them suitable for a wide range of spectroscopic applications from UV protein analysis (280nm) to visible colorimetric assays and near-IR applications.
Q: What is the correct Standard Quartz UV Cuvette with Lid direction in a spectrophotometer?
A: Insert the cuvette so that the light beam passes through the transparent (polished) sides. The polished sides should be perpendicular to the light path. Many cuvettes have arrow markings or orientation guides to indicate correct placement. The opaque sides should be parallel to the light path to prevent light scattering.
Q: What is the Standard Quartz UV Cuvette with Lid absorbance range?
A: For accurate measurements, the recommended absorbance range is 0.1-1.0 AU (absorbance units). Values below 0.1 may have high relative error due to instrument noise, while readings above 1.0 may show deviation from linearity. For concentrated samples exceeding this range, dilution or shorter path length cuvettes are recommended.
Q: How to clean Standard Quartz UV Cuvettes with Lid properly?
A: For routine cleaning, rinse with the solvent used in your analysis, followed by deionized water and a final rinse with spectroscopic-grade acetone or ethanol. For stubborn residues, soak in dilute HCl (0.1M) or specialized cuvette cleaning solution. Never use abrasive materials on optical surfaces. Air dry or use oil-free compressed air. Store in original packaging to prevent scratches.
