Usage Guide of Quartz UV Cuvette with Tube
Handling & Measurement Procedures
- Wear gloves when handling cuvettes to prevent fingerprints and contamination on optical surfaces.
- Connect tubing to the inlet/outlet tubes using appropriate fittings. For standard tubes (6-8mm OD), silicon or PTFE tubing with corresponding inner diameter provides a tight seal.
- Prime the system by slowly introducing liquid to eliminate air bubbles. For best results, introduce liquid from the bottom tube while allowing air to escape from the top.
- Position the cuvette in the spectrophotometer with optical windows aligned with the light path. The tube should be oriented vertically for best results.
- For flow measurements, maintain a steady flow rate below 10 ml/min to ensure laminar flow and avoid pressure buildups.
Cleaning & Maintenance
- After each use, flush the cuvette with an appropriate solvent compatible with your sample. For water-soluble samples, distilled water is sufficient; for organic compounds, use acetone or ethanol.
- For thorough cleaning, a solution of 5% laboratory-grade detergent in warm water can be used, followed by thorough rinsing with distilled water and finally with spectroscopic-grade solvent.
- For stubborn residues, a 10% nitric acid solution can be used (wear appropriate protection), but limit exposure to less than 10 minutes to prevent etching of the quartz surface.
- Dry thoroughly using filtered compressed air or nitrogen to prevent water spots and contamination. Never use paper towels on optical surfaces.
- Store in a clean, dust-free container with optical surfaces protected. Original packaging or dedicated cuvette storage containers are recommended.
Important Precautions
- Avoid rapid temperature changes that can cause thermal shock and cracking.
- Never apply excessive force to the tube connections; use gentle, even pressure when attaching tubing.
- Hydrofluoric acid (HF) is the only common chemical that will attack quartz and should never be used for cleaning.
- Do not exceed 20 psi (1.4 bar) of internal pressure during flow operations to prevent tube separation or cuvette damage.

FAQ
Q: What type of tubing can be connected to the cuvette tubes?
A: TOQUARTZ® standard cuvettes with tube feature tube diameters of 6-8mm OD, compatible with flexible tubing such as silicone, PTFE, or PVC with corresponding inner diameters. Custom tube diameters and specialized connection fittings are available upon request.
Q: What is the maximum pressure these cuvettes can withstand?
A: TOQUARTZ® Standard models are designed for low-pressure applications up to 20 psi (1.4 bar). For high-pressure applications, we offer reinforced designs that can withstand up to 100 psi (6.9 bar) with specialized tube connections and thicker walls.
Q: Can the cuvettes with tube be used for high-temperature applications?
A: Yes, TOQUARTZ® quartz cuvettes can handle temperatures up to 1100°C. However, when using with tubes, the practical temperature limit depends on the connection materials. Standard configurations are suitable for applications from -40°C to 200°C. For higher temperatures, special high-temperature sealing methods can be implemented.
Q: Can you produce cuvettes with specific tube angles or orientations?
A: Yes, we can customize the tube angle, orientation, and position according to your requirements. This is particularly useful for integration with specific equipment or to optimize flow dynamics within the cuvette. Our engineering team can work with your specifications or help design an optimal configuration.
Q: Are these cuvettes compatible with standard spectrophotometers?
A: Yes, our standard models are designed to fit most commercial spectrophotometers with 12.5×12.5mm cuvette holders. The tube extends vertically from the top of the cuvette, allowing proper placement in standard instruments while providing connection access.
