Usage Guide of Micro Quartz UV Cuvette Cell 2 Polished Sides with Lid
Proper Handling
- Always handle cuvettes by the non-optical sides to prevent fingerprints and contamination of optical surfaces.
- Use lint-free optical tissues or gloves when handling to minimize contamination.
- Avoid placing cuvettes on hard surfaces that could scratch the optical faces.
- Insert and remove from spectrophotometers carefully to prevent chipping or cracking.
Cleaning Procedures
- Rinse with ultrapure water or appropriate solvent immediately after use.
- For stubborn residues, soak in dilute (0.1M) HCl or non-abrasive laboratory detergent solution.
- Clean optical surfaces with spectroscopic-grade solvents (methanol, acetone) and optical wipes.
- Air dry in a dust-free environment or use filtered compressed air for drying.
Sample Loading
- Fill to approximately 80% capacity (440-480μl) to allow for thermal expansion.
- Use precision micropipettes for accurate volume dispensing.
- Ensure no air bubbles are present in the light path as they can distort readings.
- Secure lid properly to prevent evaporation and contamination.
Storage Recommendations
- Store in original packaging or dedicated cuvette storage containers.
- Keep in dust-free, dry environment at room temperature.
- Avoid storage near corrosive chemicals or sources of contamination.
- For long-term storage, ensure cuvettes are completely clean and dry.
Important Usage Notes
- Avoid rapid temperature changes that may cause thermal shock and cracking.
- Do not use abrasive cleaning materials that could scratch optical surfaces.

FAQ
Q: Why use a Micro Quartz UV Cuvette with 2 polished sides and lid?
A: The 2 polished sides configuration is optimal for standard spectrophotometric analysis where light passes through the sample in a single axis. This design provides a defined path length (4mm in our standard model) for accurate absorption measurements while minimizing material costs. The lid serves three critical purposes: preventing sample evaporation during analysis (especially important for volatile solvents), reducing contamination risk, and eliminating meniscus formation that can interfere with readings. For applications requiring fluorescence or 90° detection, we offer 4-sided polished versions as a custom option.
Q: What is the wavelength range of Micro Quartz UV Cuvette Cells?
A: TOQUARTZ® Micro Quartz UV Cuvette Cells offer an exceptionally wide wavelength range of 200-2500nm, covering the UV, visible, and near-infrared regions of the spectrum. This makes them versatile for numerous analytical techniques. The high-purity fused quartz material (max. up to 99.995% SiO₂) provides superior transmission in the deep UV range, with ≥85% transmission at 200nm, ≥88% at 220nm, and ≥90% at 260nm. This performance is critical for applications like DNA/RNA quantification, protein analysis, and other UV-dependent analytical methods that require detection in the 200-400nm range where glass cuvettes are unsuitable.
Q: What is the path length of the Micro Quartz UV Cuvette and why is it important?
A: TOQUARTZ® standard Micro Quartz UV Cuvette Cell (AT-BSM-009) features a 4mm path length with a precision tolerance of ±0.01mm. The path length is the distance light travels through the sample and is critical for quantitative analysis using Beer-Lambert law calculations. The 4mm path length offers an optimal balance between sensitivity and sample volume requirements. For samples with higher concentration, the shorter path length (compared to standard 10mm cuvettes) allows direct measurement without dilution, while still requiring only 560μl of sample. Custom path lengths from 0.5mm to 10mm are available upon request for specific application requirements.
Q: What is the solvent compatibility of Micro Quartz UV Cuvette Cells?
A: TOQUARTZ® Micro Quartz UV Cuvette Cells exhibit excellent chemical resistance and are compatible with most laboratory solvents and solutions. They can withstand acids (except hydrofluoric acid), bases, alcohols, ketones, aliphatic and aromatic hydrocarbons, and aqueous solutions. The fused quartz material is highly resistant to chemical attack, making it suitable for a wide range of analytical applications. However, avoid prolonged exposure to hydrofluoric acid (HF) and hot concentrated phosphoric acid, which can etch quartz surfaces. Note that the lid material (standard PTFE/PE) may have different chemical compatibility than the quartz body; custom lid materials are available for specific solvent requirements.
Q: What is the correct orientation for a Micro Quartz UV Cuvette with 2 polished sides?
A: Proper orientation of a Micro Quartz UV Cuvette with 2 polished sides is essential for accurate measurements. The polished sides (optical windows) should align with the light path of your spectrophotometer. In most instruments, this means positioning the cuvette so that the clear, polished sides face the light source and detector, while the frosted or non-polished sides are perpendicular to the light path. Our cuvettes typically have small orientation marks or frosted sides to help identify the optical path direction. For Z-dimension spectrophotometers, ensure the appropriate height alignment using adapters if necessary. If using for fluorescence measurements, position the cuvette so that the excitation beam enters through a polished face and fluorescence detection occurs at 90° through a non-polished side (or use our 4-sided polished cuvettes for this application).
