Cuvette KJ135 (CAT#: STEM-BC-1311-ZJF)

The KJ135 cuvette is a precision optical cell designed for photometric and spectrophotometric measurements in clinical chemistry analyzers and laboratory spectrophotometers. It is manufactured from optical-grade polystyrene (PS) or optical glass with tight dimensional tolerances to ensure consistent path length and minimal stray-light interference. The cuvette geometry is matched to the optical path and holder dimensions of specific instrument platforms to ensure correct positioning, seating, and optical alignment. Available configurations include single-use polystyrene cuvettes for clinical analyzer integration and reusable glass cuvettes for research-grade spectrophotometers. The inner walls are optically polished to minimize surface scattering and ensure accurate absorbance readings at clinically relevant wavelengths. The cuvette is chemically resistant to the reagent matrices used in standard clinical chemistry assays including aqueous buffers, mild acids, and enzyme substrates. Single-use designs eliminate the carryover risk associated with inadequate cleaning of reusable cuvettes, improving result reliability in high-volume clinical workflows. Matched cuvette sets are available for applications where identical path-length performance is required across reference and sample measurements. The product is validated for compatibility with the stated analyzer platforms and meets the photometric performance requirements specified by the instrument manufacturer. It is suitable for clinical chemistry panels, immunoturbidimetric assays, enzyme kinetic assays, and colorimetric diagnostic applications.
