Quartz 10mm Fluorescence Stopper Cuvette, 700ul, Sintered 83, Four-Way Light, Stopper, 1pc/ea, C104SR11
Description
The C104SR11 is a premium quartz fluorescence cuvette with 10 mm path length and four-way light optical configuration — all four vertical faces are polished to optical grade, providing the standard 90° fluorescence geometry plus additional optical access. With a micro 700 µl internal volume (10 × 10 × 43 mm chamber), the cell is compatible with most commercial fluorimeters and UV-Vis spectrophotometers. Fabricated using Sintered 83 (>83% transmittance) — assembled by sintering quartz panels at approximately 600 °C, producing fused joints with no adhesive. Includes a PTFE stopper for gas-tight sealing, suitable for volatile solvents and air-sensitive samples.

Fluorescence Applications
Why Four-Way Light?
The four-way configuration polishes all four vertical faces plus the bottom to optical grade, providing maximum geometric flexibility for excitation and emission collection. This enables front-face fluorescence on opaque or highly concentrated samples, polarization anisotropy measurements requiring precise alignment, and bottom-read configurations used in plate-reader-adapted instruments. If your experiment only requires standard 90° fluorescence geometry, a four-way cuvette is sufficient; choose four-way when you need bottom optical access or plan to rotate the cuvette for multi-angle studies.
PTFE Stopper Closure
The precision-ground PTFE stopper provides a gas-tight seal, preventing solvent evaporation and protecting air-sensitive samples during extended fluorescence measurements. PTFE is chemically inert and contributes no background fluorescence, ensuring clean emission spectra. The stopper can be quickly removed for sample addition or replacement between measurements.
Why Sintered 83 Construction?
Sintered 83 cuvettes are assembled by fusing quartz panels at approximately 600 °C, producing joints that are integral to the quartz body with no adhesive. This thermal fusion process yields transmittance >83% and eliminates adhesive-related degradation pathways. The fused joints are compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone). For fluorescence work, the absence of adhesive also removes a potential source of background fluorescence that can contaminate emission spectra.
