Description

The C054TR1 is a quartz threaded fluorescence micro cuvette with 5mm 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 875ul internal volume (5 × 5 × 39 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-lined screw cap threads securely onto the cuvette, providing a leak-proof seal that prevents evaporation of volatile solvents and protects air-sensitive samples. Showcases a matched pair of identical threaded fluorescence cuvettes, each with precision screw threads and white PTFE caps, presented side by side to highlight manufacturing consistency for paired-measurement applications.

◆ 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-Lined Screw Cap?

The internal-thread screw cap design provides the most secure closure available for standard cuvettes. Unlike friction-fit caps or stoppers, the threaded connection resists accidental opening during sample handling, vortex mixing, or transport. The PTFE liner ensures chemical inertness and a tight seal against vapour loss — critical when working with volatile organic solvents, concentrated acids, or extended kinetic measurements. The screw cap can be repeatedly removed and replaced without degradation.

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.
