Usage Guide of Fused Quartz Micro UV Cuvette with Lid
Cleaning Protocol
- Immediately after use, rinse with deionized water or appropriate solvent compatible with your samples.
- For routine cleaning, use mild laboratory detergent (1-2% solution) and rinse thoroughly.
- For persistent residues, soak in 0.1M HCl or ethanol for 30 minutes, then rinse.
- Avoid abrasive materials that might scratch the optical surfaces.
- Dry using compressed oil-free air or nitrogen, or allow to air dry in a dust-free environment.
- For sterilization, rinse with 70% ethanol followed by sterile water, or use UV irradiation.
Proper Handling and Sample Loading
- Always handle cuvettes by the frosted or ribbed sides, never touching the optical windows.
- When filling, use a micropipette to carefully introduce sample along the inside wall to avoid bubbles.
- Fill to the recommended volume for your model (350μl-1750μl depending on model).
- Secure the lid by gentle pressure or twisting motion (depending on lid type) until firmly seated.
- Before measurement, check for air bubbles by holding the cuvette at eye level against a light source.
- Always orient the cuvette in the spectrophotometer with the transparent windows facing the light path.
Storage Recommendations
- Store clean, dry cuvettes in the original protective case or dedicated cuvette rack.
- Keep in a dust-free environment at room temperature.
- Avoid direct contact between optical windows and any surfaces.
- For long-term storage, consider using desiccant to prevent moisture accumulation.
Extending Cuvette Lifespan
- Equilibrate samples to room temperature before measurement to prevent thermal stress.
- Avoid rapid temperature changes that could create thermal shock.
- Use compatible solvents - while fused quartz is highly resistant, prolonged exposure to strong bases at high temperatures should be avoided.
- Periodically check for scratches or etching that might affect optical performance.
- Follow manufacturer guidelines for compatible pH range (TOQUARTZ cuvettes: pH 1-14).

FAQ
Q: What types of lids are available for TOQUARTZ Fused Quartz Micro UV Cuvettes?
A: We offer several lid options for our Micro UV Cuvettes: 1) Standard PTFE lids for general applications; 2) Screw-cap lids for secure sealing of volatile samples; 3) Septum lids for applications requiring sample injection or withdrawal; 4) Flow-through lids with tubing connections for continuous monitoring applications. Custom lid designs are also available upon request.
Q: How do TOQUARTZ Fused Quartz Micro UV Cuvettes compare to plastic disposable cuvettes?
A: While plastic disposable cuvettes offer convenience, they have significant limitations compared to fused quartz: 1) Most plastics cannot be used below 340nm in the UV range; 2) Plastic cuvettes have lower chemical resistance and can be damaged by many solvents; 3) Dimensional stability and optical clarity are typically inferior; 4) Fused quartz cuvettes provide long-term durability and higher accuracy, making them more cost-effective for routine laboratory use despite the higher initial investment.
Q: What is the wavelength range of TOQUARTZ Fused Quartz Micro UV Cuvettes?
A: TOQUARTZ Fused Quartz Micro UV Cuvettes offer excellent optical transmission across the 200-2500nm wavelength range, making them suitable for both UV and visible spectroscopy applications. They provide particularly high transmission in the UV range (200-380nm) where many biological and chemical compounds exhibit characteristic absorption.
Q: How do I clean Fused Quartz Micro UV Cuvettes with Lid?
A: For routine cleaning, rinse the cuvette immediately after use with deionized water or an appropriate solvent. For more thorough cleaning, use a mild laboratory detergent solution (1-2%), followed by thorough rinsing with deionized water. For persistent residues, soak in 0.1M HCl or ethanol for 30 minutes. Always avoid abrasive materials that could scratch the optical surfaces, and dry using compressed oil-free air/nitrogen or in a dust-free environment.
Q: What is the path length of TOQUARTZ Fused Quartz Micro UV Cuvettes?
A: TOQUARTZ® standard Fused Quartz Micro UV Cuvettes feature a 10mm path length, which is the industry standard for most spectrophotometric applications. This allows for direct concentration calculations using the Beer-Lambert Law without additional conversion factors. We also offer custom path lengths ranging from 1mm to 100mm for specialized applications upon request.
Q: What solvent compatibility do Fused Quartz Micro UV Cuvettes offer?
A: Fused quartz offers exceptional chemical resistance and is compatible with most laboratory solvents and reagents. This includes water, alcohols, acetone, most acids (except hydrofluoric acid), bases, organic solvents, and salt solutions. The material is stable across the pH range of 1-14 at room temperature, making it suitable for a wide variety of analytical applications.
