Semi-Micro Synthetic Quartz Cuvette 1.4mL (LAQ-264)

Premium 1.4 mL Fused Silica Cells for Low-Volume UV-Vis Spectroscopy

The LARK LAQ-264 is a high-precision, semi-micro spectrophotometer cell engineered for demanding quantitative analysis when liquid sample volumes are heavily restricted. Precision-crafted from premium synthetic fused quartz by LARK (France), this cell reduces the required sample size down to just 1.4 mL while retaining a standard 10 mm optical path length. It is the ideal configuration for molecular biology research, trace DNA/RNA profiling, protein quantification, and sensitive chemical assays where conserving expensive reagents or rare biological extracts is paramount.

Key Features

• Sample-Conserving 1.4 mL Volume: Features a narrowed internal sample chamber that slashes fluid volume requirements by over 60% compared to traditional 3.5 mL macro cuvettes, preventing sample waste without reducing absorbance sensitivity.
• Full-Spectrum Ultraviolet Clarity: Optimized for a broad transmission range from 190 nm to 2,500 nm. It delivers excellent transparency (>80% at 200 nm), allowing for highly accurate, artifact-free baselines in the deep UV spectrum.
• Universal Equipment Footprint: Built to universal standard outer dimensions (12.5 x 12.5 x 45 mm). This design seamlessly fits standard multi-cell holders, cell changers, and spectrophotometer compartments without needing extra adapters.
• No-Adhesive Thermal Fusion: Assembled using advanced thermal bonding technology with zero glues, resins, or chemical adhesives. This guarantees permanent structural integrity and completely eliminates the risk of adhesive leaching.
• Exceptional Chemical & Thermal Resilience: Fully inert to concentrated acids, strong bases, and aggressive organic solvents (such as chloroform, acetone, or DMSO). It is completely autoclavable and safe for use with temperature-controlled peltier systems.
