Usage Guide of Micro Quartz Glass UV Cuvette Cell with Stopper
Sample Preparation and Loading
- Ensure cuvette is clean and dry before use. Handle by the frosted or ribbed sides only, never touch the optical windows.
- Fill the cuvette to approximately 80% capacity (approximately 550-600μl) to prevent overflow when inserting the stopper.
- Insert stopper gently with a slight twisting motion to ensure a secure seal without putting pressure on the cuvette walls.
- Check for air bubbles in the light path and gently tap the cuvette to remove them if present.
Cleaning Procedure
- Immediately after use, rinse with deionized water or appropriate solvent to remove sample residue.
- For persistent residues, soak in mild laboratory detergent solution for 1-2 hours, then rinse thoroughly.
- For organic residues, clean with acetone or ethanol followed by thorough rinsing with deionized water.
- Air dry or use filtered compressed air. Avoid using paper tissues on optical surfaces to prevent scratches.
Storage Recommendations
- Store clean, dry cuvettes in their original container or dedicated cuvette storage box.
- Keep in dust-free environment at room temperature away from direct sunlight.
- Avoid storage near corrosive chemicals or environments with high humidity.
- For long-term storage, leave stopper slightly loose to prevent potential sticking.
Important Precautions
- Avoid rapid temperature changes that may cause thermal shock and crack the quartz material.
- Never use ultrasonic cleaners as they may damage the cuvette structure or optical surfaces.
- Avoid exposing cuvettes to hydrofluoric acid (HF) which can etch and damage quartz surfaces.
- Do not exceed the maximum temperature rating of 100°C to prevent thermal stress and potential damage.

FAQ
Q: Why use a Micro Quartz UV Cuvette with stopper instead of standard cuvettes?
A: Micro quartz UV cuvettes with stoppers offer several advantages over standard cuvettes: (1) They require smaller sample volumes (700μl vs. 2-3ml for standard cuvettes), conserving precious or limited samples; (2) The stopper prevents evaporation and contamination during measurements or storage; (3) Their quartz construction allows for UV range measurements below 320nm where glass or plastic cuvettes cannot be used; (4) They provide greater stability for kinetic measurements that may require extended analysis times. These features make them particularly valuable for applications with limited sample availability or when working with volatile or sensitive materials.
Q: What is the wavelength range of your Micro Quartz UV Cuvette with stopper?
A: TOQUARTZ® Micro Quartz UV Cuvette Cell with Stopper operates effectively across a wavelength range of 200-2500nm. This broad range covers the ultraviolet (UV), visible, and near-infrared regions of the electromagnetic spectrum. The high-purity quartz material (≥99.995% SiO₂) ensures excellent transmission characteristics throughout this range, with transmission rates exceeding 85% at wavelengths as low as 190nm. Unlike glass or plastic alternatives, these cuvettes have no significant absorption peaks within their operating range, making them ideal for comprehensive spectroscopic analysis without material interference.
Q: What is the path length of your standard Micro Quartz UV Cuvette with stopper?
A: TOQUARTZ® standard Micro Quartz UV Cuvette Cell with Stopper (model AT-BSM-042) features a 10mm path length with a tolerance of ±0.1mm. This path length is the industry standard for most spectrophotometric analyses and aligns with the Beer-Lambert law calculations commonly used in analytical chemistry. The precision of this path length is critical for accurate concentration measurements, as variations would directly affect absorbance readings. For specialized applications, we also offer custom path lengths ranging from 1mm (for highly concentrated samples) to 100mm (for trace analysis), all manufactured to the same exacting tolerance standards.
Q: What is the absorbance range for the Micro Quartz UV Cuvette with stopper?
A: TOQUARTZ® Micro Quartz UV Cuvette Cell with Stopper can effectively measure absorbance values from 0 to approximately 3.0 Absorbance Units (AU). However, the practical upper limit typically depends on the spectrophotometer being used rather than the cuvette itself. Most modern spectrophotometers deliver linear responses up to 2.0 AU, with decreasing accuracy above this level. The high optical clarity of our quartz material ensures that the cuvette itself contributes minimal background absorbance, allowing for accurate measurement of very low concentrations when paired with an appropriate instrument.
Q: Why are UV Quartz Micro Cuvettes with stopper used in UV spectroscopy?
A: UV Quartz Micro Cuvettes with stoppers are essential for UV spectroscopy because: (1) Quartz is transparent to ultraviolet light, unlike glass or plastic which absorb in the UV range; (2) Many biomolecules and compounds have characteristic absorption peaks in the UV region (190-380nm) that require quartz cuvettes for detection; (3) The stopper prevents evaporation or contamination of small sample volumes during analysis; (4) The micro format conserves valuable or limited samples while maintaining measurement accuracy; (5) High-purity quartz provides consistent optical properties with no interfering absorption peaks. These features make them indispensable for applications like DNA/RNA quantification, protein analysis, and pharmaceutical compound characterization.
