Usage Guide of Quartz Micro Fluorescence Cuvettes
Handling & Storage
- Always handle cuvettes with gloves to prevent fingerprints and contamination of optical surfaces.
- Store cuvettes in their original containers or dedicated storage boxes when not in use.
- Avoid direct contact between cuvettes to prevent scratches on optical surfaces.
- Store in a clean, dust-free environment away from chemical vapors.
- For cuvettes with lids, ensure lids are properly seated when storing to prevent contamination.
Cleaning & Maintenance
- Clean immediately after use to prevent sample residue buildup and contamination.
- For routine cleaning, rinse with distilled water followed by spectroscopic-grade solvent (ethanol, methanol, or acetone).
- For stubborn residues, soak in dilute acid solution (0.1M HCl or HNO₃) followed by thorough rinsing.
- Air dry or use oil-free compressed air. Avoid wiping optical surfaces with paper or cloth.
- For black wall cuvettes, take extra care to avoid abrasive cleaning methods that could damage the coating.
Measurement Best Practices
- Before measurements, inspect cuvettes for cleanliness and scratches that could affect readings.
- Always handle cuvettes by the non-optical sides (typically the frosted or ribbed surfaces).
- Ensure proper orientation in your instrument – optical path windows should align with the light beam.
- Avoid rapid temperature changes that could cause thermal stress to the quartz material.
- For micro-volume cuvettes, ensure samples are properly loaded to avoid air bubbles and achieve correct path length.
- When using with fluorescent samples, minimize exposure to excitation light when not measuring to prevent photobleaching.
