Usage Guide of Standard Quartz Glass Round Bottom UV Cuvette
Cleaning and Maintenance
-
Immediate Rinsing
Rinse with deionized water immediately after use to prevent sample residue from drying on surfaces. -
Cleaning Solutions
For stubborn residues, use dilute laboratory detergent solutions, followed by thorough rinsing with deionized water. For organic residues, ethanol or methanol can be effective. -
Avoid Abrasives
Never use abrasive cleaners or brushes that could scratch the optical surfaces. -
Drying
Air dry in a dust-free environment or use pure compressed air/nitrogen to blow-dry. Avoid paper towels which can leave fibers. -
Storage
Store clean, dry cuvettes in their original containers or dedicated storage racks to protect optical windows from scratches and contamination.
Handling and Measurement Procedures
-
Sample Preparation
Filter samples when possible to remove particulates that might scatter light and affect readings. -
Filling the Cuvette
Fill to approximately 2/3 capacity (about 2.5ml) to ensure the light path passes through the sample without interference from the meniscus. -
Bubble Removal
Gently tap the round bottom of the cuvette to dislodge any air bubbles that might interfere with readings. -
Cuvette Orientation
Place the cuvette in the spectrophotometer with the transparent optical windows facing the light path. The opaque sides should be perpendicular to the light path. -
Handling Optical Surfaces
Never touch the optical windows with bare fingers. Always handle the cuvette by the top or opaque sides.

FAQ
Q: What is the wavelength range of Standard Quartz UV Cuvettes Round Bottom with Lid?
A: TOQUARTZ® Standard Quartz UV Cuvettes Round Bottom with Lid have an effective transmission range from 200nm to 2500nm, covering the entire UV and visible spectrum plus portions of the near-infrared range. This broad spectral coverage makes them versatile for multiple analytical applications. The transmittance is >80% across this range, with special attention to performance in the critical UV range (200-350nm) where many biomolecules have characteristic absorption peaks.
Q: What is the path length of Standard Quartz UV Cuvettes Round Bottom with Lid?
A: The standard path length for our model AT-BSM-010 Quartz UV Cuvette is 10mm (1cm), which is the most commonly used dimension in laboratory spectrophotometers. This path length is the distance light travels through the sample, and is critical for concentration calculations using Beer-Lambert law. We also offer custom path lengths ranging from 1mm (for highly concentrated samples) to 100mm (for very dilute solutions) upon request.
Q: How to clean Standard Quartz UV Cuvette Round Bottom with Lid?
A: For optimal performance, clean Standard Quartz UV Cuvettes immediately after use by rinsing with deionized water. For stubborn residues, use dilute laboratory detergent or appropriate solvents (ethanol, methanol, or acetone for organic residues), followed by thorough rinsing with deionized water. Never use abrasive cleaners or brushes that could scratch the optical surfaces. Air dry in a dust-free environment or use pure compressed air/nitrogen. Store clean, dry cuvettes in their original containers to protect optical windows from scratches and contamination.
Q: What solvents are compatible with Standard Quartz UV Cuvettes Round Bottom with Lid?
A: Standard Quartz UV Cuvettes are compatible with most laboratory solvents including water, aqueous buffers, alcohols (methanol, ethanol), acetone, acetonitrile, DMSO, dilute acids and bases, hexane and other hydrocarbons, chloroform, and most organic solvents. The high chemical resistance of quartz makes these cuvettes suitable for diverse analytical applications. However, hydrofluoric acid (HF) and concentrated hot alkaline solutions should be avoided as they can etch quartz surfaces.
Q: What is the Standard Quartz UV Cuvette Round Bottom with Lid direction for spectrophotometer placement?
A: When placing a Standard Quartz UV Cuvette Round Bottom with Lid in a spectrophotometer, the transparent optical windows should face the light path (typically the clear sides). The opaque sides (usually frosted or ribbed) should be perpendicular to the light path. Most cuvettes have a small arrow or mark indicating the correct orientation. Always handle the cuvette by the top or opaque sides to avoid fingerprints on the optical windows, which can interfere with measurements.
Q: What is the absorbance range of Standard Quartz UV Cuvettes Round Bottom with Lid?
A: Standard Quartz UV Cuvettes Round Bottom with Lid from TOQUARTZ® have minimal intrinsic absorbance in the UV-VIS range, typically less than 0.01 AU (absorbance units) across the 200-2500nm range. This low background absorbance allows for accurate measurement of sample absorbance without significant blank correction. The practical measurement range depends on your spectrophotometer sensitivity, but typically spans from 0.001 AU (for highly sensitive instruments) to 3.0 AU for most standard laboratory spectrophotometers.
