Description

The C052CR2 is an IR quartz (JGS3 fused silica) standard cuvette with 5 mm path length and two-way light optical windows, designed for Vis-NIR and mid-IR spectrophotometry across a broad 260–3500 nm wavelength range. The two-way light configuration transmits the beam through two opposing polished optical faces while the frosted sides minimize stray light interference, delivering clean baseline performance for absorbance measurements in the near- and mid-infrared regions. Fabricated using Sintered 83 — a high-temperature sintering process at 600 °C that fuses quartz components without adhesive — this cuvette achieves >83% transmittance and excellent chemical resistance to acids, bases, and organic solvents. The 1.75 ml volume accommodates standard sample volumes, and the PTFE cap provides an inert, chemical-resistant seal. Supplied as a pack of two for cost-effective parallel or comparative experiments.

Applications

◆ Near-infrared (NIR) absorbance spectroscopy for organic compound analysis

◆ Mid-infrared (MIR) measurements of O–H, C–H, and N–H overtone bands

◆ FTIR liquid transmission cells for aqueous and non-aqueous solutions

◆ Pharmaceutical QC of active ingredients via NIR/MIR absorption

◆ Petrochemical and fuel analysis (hydrocarbon fingerprinting)

◆ Environmental monitoring of water contaminants in the IR region

Why This Cuvette?

The 5 mm path length reduces absorbance by 2× compared to a standard 10 mm cuvette (Beer-Lambert law: A = εlc), making it well-suited for moderately concentrated samples that would saturate a longer-path cell in the IR region. IR quartz (JGS3) extends the useful wavelength range to 3500 nm — far beyond standard quartz (JGS1, which cuts off at ~2500 nm) — enabling measurements of fundamental molecular vibrations and overtone bands that are invisible in the UV-Vis range. The Sintered 83 fabrication provides a jointless, high-transmittance optical path that withstands repeated thermal cycling and aggressive cleaning protocols without degradation.

Usage Tips: Handle the cuvette by its frosted (non-optical) sides to avoid fingerprints on the polished windows — even trace skin oils absorb strongly in the mid-IR and will distort your spectra. Fill to at least 15 mm above the beam center height. For IR measurements, ensure your reference (blank) uses the same cuvette type to cancel out any residual JGS3 absorption features. Clean with spectroscopic-grade solvent and lint-free tissue; avoid water residue for MIR work as the broad O–H absorption band will interfere. Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Bruker FTIR, and most commercial spectrophotometers with standard 12.5 mm cuvette holders.
