4.5mL Polystyrene Spectrophotometer Cuvette, 10mm Path, 2 Clear Sides — 1000/Case
The Globe Scientific 4.5mL Polystyrene Spectrophotometer Cuvette (111117) is the standard disposable cuvette for clinical chemistry, pharmaceutical QC, and research labs running colorimetric and absorbance-based assays in the visible spectrum. Optical-grade polystyrene provides transmittance across the 340–800nm range with ±1% absorption variation between cuvettes — the reproducibility tolerance required for batch analysis where inter-cuvette consistency directly affects assay accuracy. Dust-free PE foam tray packaging in 100-cuvette trays maintains optical surface integrity through the point of use.
Key features
- Optical polystyrene construction delivers consistent transmittance across the 340–800nm visible spectrum with ±1% inter-cuvette absorption variation — the precision threshold required for batch colorimetric analysis where small absorbance differences between standards and unknowns drive quantitative results
- Standard 10mm path length and 4.5mL capacity fit the most common spectrophotometer cell holder configurations, making this cuvette compatible with instruments from Thermo Scientific, Shimadzu, Agilent, Hach, and virtually all major spectrophotometer manufacturers
- Two clear optical windows with two frosted sides orient correctly in any spectrophotometer beam path — frosted sides prevent light scatter from non-optical surfaces, improving signal-to-noise ratio compared to four-sided clear cuvettes in single-beam instruments
- Dust-free PE foam tray packaging holds 100 cuvettes per tray in protected individual positions — prevents optical surface scratching and contamination between trays during storage and handling that compromises absorbance readings

Applications
Used in clinical chemistry labs, pharmaceutical QC, environmental testing, food and beverage analysis, and university research labs for colorimetric quantification, enzyme kinetics, protein determination, and any visible-spectrum absorbance assay requiring disposable single-use cuvettes at standard 10mm path length. The 1000/case volume provides significant per-unit cost reduction over smaller quantity purchases from major distributors for labs running high daily cuvette volumes.
