Usage Guide of Malvern Quartz UV Cuvette
Proper Handling & Cleaning
- Always handle cuvettes by the non-optical sides (frosted or ribbed sides) to prevent fingerprints on optical windows.
- Clean immediately after use with an appropriate solvent compatible with your sample, followed by ultrapure water and ethanol rinse.
- For persistent contaminants, soak in diluted laboratory detergent (2-5%) for 30 minutes, then rinse thoroughly.
- Avoid abrasive materials that can scratch optical surfaces—use only lint-free optical tissues or microfiber cloths.
- For final drying, use filtered compressed air or nitrogen, or allow to air dry in a dust-free environment.
Measurement Best Practices
- Align cuvette in the spectrometer with optical windows perpendicular to the light beam path.
- Fill to appropriate volume (typically 2/3 of height) to ensure beam passes through sample.
- Check for air bubbles by gently tapping cuvette before measurement—bubbles can interfere with readings.
- Use matched pairs of cuvettes for reference and sample measurements to minimize baseline variations.
- For temperature-sensitive applications, allow cuvette and sample to equilibrate before measurement.
Storage Recommendations
- Store clean, dry cuvettes in original protective case or dedicated cuvette storage rack.
- Maintain dust-free environment to prevent optical surface contamination.
- Avoid storage near corrosive chemicals or environments with high humidity.
- If not using for extended periods, verify cleanliness before next use.

FAQ
Q: What is a Malvern Quartz UV Cuvette and how does it differ from standard cuvettes?
A: A Malvern Quartz UV Cuvette is a high-precision optical cell designed specifically for UV-Visible spectroscopy applications. It features standardized dimensions (typically 12x12x45mm) compatible with Malvern instruments and most standard spectrophotometers. Unlike standard glass cuvettes, quartz UV cuvettes offer superior transmittance in the UV range (down to 190nm) and greater chemical resistance, making them ideal for a wider range of analytical applications.
Q: Why use a Malvern Quartz UV Cuvette instead of glass or plastic? Cuvette with stopper?
A: Quartz cuvettes are essential when analyzing samples in the UV spectrum below 320nm, where glass absorbs light and produces inaccurate readings. They offer superior chemical resistance compared to plastic cuvettes, withstanding organic solvents that would damage or cloud plastic. Additionally, quartz provides better thermal stability, allowing analysis at higher temperatures, and delivers more consistent results over time due to its durability and resistance to scratching or chemical etching.
Q: What wavelength range can Malvern Quartz UV Cuvettes accommodate?
A: TOQUARTZ® Transparent Malvern Quartz UV Cuvettes provide excellent transmittance across the 190-2500nm wavelength range. This spans from deep UV through visible and into the near-infrared spectrum, making them versatile for various analytical applications. The material offers minimal absorption or fluorescence across this range, ensuring accurate spectroscopic measurements without interference from the cuvette material itself.
Q: Are TOQUARTZ Malvern Quartz UV Cuvettes compatible with all spectrophotometers?
A: TOQUARTZ® standard 12x12x45mm Transparent Malvern Quartz UV Cuvettes are compatible with most modern spectrophotometers from major manufacturers including Agilent, Thermo Scientific, Shimadzu, PerkinElmer, Beckman Coulter, and of course, Malvern instruments. For specialized instruments or older models with non-standard holders, we offer custom sizing options. We recommend verifying your instrument’s cuvette holder specifications before ordering if you’re uncertain about compatibility.
Q: Can you provide custom dimensions for Malvern Quartz UV Cuvettes?
A: Yes, TOQUARTZ® specializes in custom quartz cuvette manufacturing. We can produce Transparent Malvern Quartz UV Cuvettes with custom dimensions, including non-standard path lengths (1-100mm), altered external dimensions to fit specialized instruments, custom chamber volumes, and specialized optical window configurations. Our engineering team works directly with customers to design cuvettes for specific applications, providing technical drawings for approval before production. Custom orders typically require 2-3 weeks lead time, with no minimum order quantity for most customizations.
