IR Quartz (JGS3) 10mm Screw-Cap Cuvette, 3.5ml, Molded 83, Four-Way Light, Screw Cap, 1pc/ea, C104TE4
Description
The C104TE4 is a premium IR quartz (JGS3) 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 standard 3.5 ml internal volume (10 × 10 × 53 mm chamber), the cell is compatible with UV-Vis, NIR, and FTIR spectrophotometers as well as commercial fluorimeters. Fabricated using Molded 83 (>83% transmittance) — the cuvette body is integrally fused as a single piece with no adhesive joints. Made from JGS3 infrared quartz glass, the cell transmits across 260–3500 nm — extending well into the near-infrared and mid-infrared region where standard UV quartz (JGS1) is opaque. Features a PTFE-lined screw cap for secure, leak-resistant closure during mixing, inversion, or transport.

IR & Fluorescence Applications
Why Four-Way Light?
The four-way configuration polishes all four vertical faces to optical grade — the standard geometry for fluorescence spectroscopy. The excitation beam enters through one face and emission is collected at 90° through an adjacent face, minimizing excitation light contamination in the emission signal. The additional two polished faces allow the cuvette to be rotated for alternative measurement geometries or simultaneous absorbance monitoring during fluorescence experiments.
Screw Cap Closure
The PTFE-lined screw cap provides secure, leak-resistant closure that allows the cuvette to be inverted for mixing, transported between workstations, or used in automated sample changers without risk of leakage. The PTFE liner is chemically inert and contributes no background fluorescence. The threaded design allows one-handed operation and consistent sealing pressure.
Why JGS3 Infrared Quartz?
JGS3 (also known as IR quartz or infrared quartz glass) is a specialty optical-grade quartz with an extended transmission window from 260 to 3500 nm. Unlike standard UV quartz (JGS1, transparent 185–2500 nm), JGS3 maintains high transmittance in the near-infrared and mid-infrared region, making it essential for NIR spectroscopy, FTIR liquid analysis, and measurements in the O–H / N–H / C–H stretch absorption bands (2500–3500 nm). If your application requires only UV-Vis range (190–2500 nm), a standard quartz cuvette will suffice at lower cost. Choose JGS3 when you need IR transmission beyond 2500 nm.
Why Molded 83 Construction?
Molded 83 is the premium fabrication method: the cuvette is integrally fused as a single piece with no adhesive or joints. This eliminates solvent attack points and enables operation up to 1200 °C — far exceeding sintered (600 °C) or glue-assembled (200 °C) alternatives. Dimensional tolerance is ±0.02 mm. The monolithic construction withstands all common laboratory solvents, concentrated acids, and bases; avoid HF (hydrofluoric acid). Critically for fluorescence work, the absence of adhesive removes a common source of background fluorescence that can contaminate emission spectra. With transmittance >83%, Molded 83 is the gold standard for demanding fluorescence research.
