A quartz cuvette (also known as a quartz sample cell or fused silica cuvette) is a high-precision optical container designed to hold liquid samples for absorbance, transmission, and fluorescence measurements across a broad UV-Vis-NIR spectral range (190–2500 nm).
These spectrophotometer cuvettes provide exceptional transparency in the ultraviolet and near-infrared regions, ensuring accurate and reproducible analytical results in advanced research and quality control laboratories. Unlike standard glass cuvettes, quartz cells do not absorb in the critical UV spectrum, making them the gold standard for nucleic acid and protein quantification.
Key Applications & Scenarios
Ideal for demanding spectroscopic and fluorometric applications, our cuvettes are widely used across various scientific disciplines:
-
Life Sciences & Biochemistry: Essential for DNA quantification, RNA concentration analysis, protein assays, and enzyme kinetics studies.
-
Pharmaceutical Analysis: Used in drug dissolution testing, quality control, and method validation compliant with global pharmacopeia standards.
-
Environmental Science: Reliable for water quality monitoring, heavy metal analysis, and Chemical Oxygen Demand (COD) testing.
-
Clinical Chemistry & Food Safety: Suitable for routine diagnostic testing and food composition analysis.
-
Materials Science: Compatible with NIR spectroscopy and advanced optical material characterization.
Material Specifications & Design Features
-
Premium Material: Fabricated from high-purity UV-grade fused quartz (Synthetic Quartz Glass), ensuring maximum homogeneity and minimal optical interference.
-
Optical Precision: Features a standard 10 mm optical path length and 12.5 x 12.5 x 45 mm exterior dimensions to fit universal spectrophotometer holders.
-
Enhanced Durability: Constructed using a thermal-bonding process rather than adhesives. This provides superior resistance to aggressive solvents, strong acids, and bases, ensuring long-term reliability without leakage.
-
Clear Window Options: Available with either two polished optical windows (standard) or four polished windows (for fluorescence analysis).
