Quartz 10mm Micro Fluorescence Cuvette, 0.7 ml, Standard 80, Four-Way Light, PTFE Cap, 1pc/ea, C104CS53

Not every fluorescence assay calls for the highest-grade fabrication. The C104CS53 gives budget-conscious laboratories a practical, four-window micro cuvette at a fraction of the cost of fused alternatives — without sacrificing the core geometry required for 90° fluorescence detection. With a 2 mm interior width carved by internal masking walls, the cell holds just 0.7 ml while maintaining a full 10 mm optical path. Standard 80 construction uses precision-applied optical adhesive to deliver transmittance above 80 % across 190–2 500 nm, making it well suited to aqueous-phase screening where solvent compatibility is not a concern.

In fluorescence spectroscopy, geometry is everything: the excitation beam enters one face, and the detector sits at 90° to capture emission through an adjacent face. The C104CS53 preserves that four-window layout in a micro-volume format, so you get the same angular relationships and path-length accuracy that higher-tier cuvettes provide — just at a lower price point. Standard 80’s precision-glued joints are fully compatible with aqueous buffers, dilute acids, and most biological media, covering the vast majority of routine fluorescence workflows. Reserve fused cuvettes for organic solvents or ultra-low-background work; for everything else, this cell keeps the cost per measurement low.

A full-size 10 mm fluorescence cuvette requires 3.5 ml of sample. The C104CS53 uses internal masking walls to shrink the active chamber to 2 mm wide, bringing the fill volume down to 0.7 ml — an 80 % savings. When you are working through dozens of aqueous samples per session, that reduction adds up quickly in both reagent cost and preparation time.

Usage Tips

• Use aqueous and mildly acidic or basic solutions only — avoid organic solvents that may soften the adhesive.
• Pipette slowly into the narrow 2 mm channel to minimise air-bubble entrapment.
• Clean promptly after use with deionised water; soak in dilute detergent if protein residue is present.
• Dry with filtered air or nitrogen rather than lab tissue to prevent lint on the optical faces.
