Description

The C104SS is a quartz fluorescence cuvette with 10mm path length and four-way light optical configuration — all four vertical faces are polished to optical grade, enabling both standard UV-Vis absorbance and 90° fluorescence detection. With a 1.8ml internal volume (10 × 10 × 18 mm chamber), the cell is compatible with most commercial spectrophotometers. Fabricated using Sintered 83 (>83% transmittance) — high-temperature sintered to fuse quartz panels without adhesive. The PTFE stopper provides an airtight friction-fit seal that prevents evaporation and protects air-sensitive analytes. Showcases a short-body fluorescence cuvette (35mm height) with a large white PTFE cylindrical stopper that sits deeply into the opening, featuring notched alignment guides and a 20mm sample chamber height.

Spectroscopy Applications

◆ UV-Vis Absorbance Spectroscopy — quantitative concentration, kinetics, Beer–Lambert studies

◆ Fluorescence Spectroscopy — 90° excitation/emission for fluorescent probes, dyes, and quantum dots

◆ DNA / RNA Quantification — nucleic-acid purity checks at 260/280 nm

◆ Protein Assays — Bradford, BCA, Lowry, and direct A280 measurements

◆ Enzyme Kinetics — real-time substrate conversion and inhibition studies

◆ Water Quality & Environmental — COD, nitrate, phosphate, heavy-metal colorimetric tests

◆ Pharmaceutical QC — dissolution testing, drug concentration, stability monitoring

◆ Chemical Reaction Monitoring — reaction progress tracking via absorbance changes

Why Four-Way Light?

Four-way light cuvettes have all four vertical faces polished to optical grade, enabling both standard absorbance measurements and 90° fluorescence detection geometry. The excitation beam enters through one face while emission is collected at right angles through an adjacent face — the standard configuration required by fluorimeters and spectrofluorometers.

Why a PTFE Stopper?

The PTFE stopper provides an airtight friction-fit seal that prevents evaporation of volatile samples and protects air-sensitive analytes from atmospheric exposure. PTFE is chemically inert to virtually all laboratory solvents and reagents, making it the preferred closure material for demanding analytical work. The stopper can be easily inserted and removed for sample loading while maintaining a reliable seal during measurements.

Why Sintered 83?

Sintered 83 uses high-temperature sintering to fuse quartz panels without adhesive, delivering >83% UV transmittance from 200–2500 nm. The sintered joints are chemically inert and compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone). This fabrication is ideal for analytical workflows involving harsh chemical matrices where standard glued cells would degrade.

Usage Tips

Rinse with a compatible solvent (e.g., ethanol or the measurement solvent) before first use to remove any residual particles.
Do not use abrasive materials or brushes on the polished optical faces — wipe gently with lens tissue.
Compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone).
Store in the original protective case to prevent scratches on the optical windows.
For baseline correction, fill with your reference solvent, cap the cuvette, and run a blank before sample measurements.
