Description

For aqueous-phase fluorescence experiments that would benefit from a longer path but do not require solvent resistance or the tightest tolerances, the C204WS2 is the most cost-effective entry point. Standard 80 fabrication uses precision-applied optical adhesive to bond the quartz panels, delivering transmittance above 80 % from 190 to 2 500 nm at a lower price than fused alternatives. The 20 mm path doubles the excitation volume relative to a 10 mm cell, improving signal-to-noise on dilute aqueous fluorophores, and the four polished faces maintain the 90° geometry used by all conventional fluorimeters.

Applications

🔬 Aqueous Fluorescence Screening — Improve detection limits for water-soluble fluorophores at minimal cost

🧬 Biological Buffer Assays — Measure GFP, fluorescein, or DAPI fluorescence in PBS or Tris at higher sensitivity

🧪 Water-Quality Monitoring — Detect chlorophyll-a or humic-substance fluorescence in filtered environmental samples

💊 Teaching Fluorimetry — Affordable four-window cell for undergraduate fluorescence labs

🌡️ Pre-Screening Before Premium Cells — Triage samples in a budget cell before committing to fused cuvettes

🔭 Fluorescence Method Development — Validate new assay protocols with a wider detection window at low cost

Standard 80 — Maximum Value for Aqueous Work

Not every fluorescence experiment needs solvent-resistant joints or sub-micron tolerances. When the sample matrix is aqueous — buffers, dilute acid, growth media — the precision-glued construction of Standard 80 performs reliably and costs significantly less than fused alternatives. The C204WS2 lets budget-conscious labs access the sensitivity benefits of a 20 mm path length without the price premium of Sintered or Molded fabrication. Reserve fused cells for organic solvents and ultra-low-background work; for routine aqueous fluorescence, this cell delivers the geometry and clarity you need at the lowest cost per measurement.

Usage Tips

Use aqueous and mildly acidic or basic solutions only — avoid organic solvents that may soften the adhesive.
Fill at a slight tilt to prevent air bubbles along the 20 mm light path.
Clean promptly with deionised water; soak briefly in dilute detergent for stubborn protein residues.
Dry with filtered air rather than lab tissue to prevent lint on the optical faces.
