Engineered from synthetic fused silica (JGS1) and electric-melt quartz (JGS2/JGS3) with molecular-level direct bonding and helium leak-integrity certification.
From conventional static cuvettes to sub-nanoliter continuous dynamic detection channels: How ultra-pure fused silica is driving quantum leaps in analytical sensitivity.
Unlike borosilicate or optical plastics that suffer solarization and severe absorption below 340 nm, synthetic high-purity quartz flow cells deliver flat spectral transmission exceeding 92% across the deep ultraviolet spectrum, essential for peptide bond absorption at 214 nm and nucleic acid quantification at 260 nm.
Epoxy and solvent-based bonding methods degrade under harsh organic HPLC mobile phases like acetonitrile and tetrahydrofuran. Next-generation flow cells utilize high-temperature thermal molecular fusion, bonding quartz components at >1,150°C to create monolithic bodies that eliminate leak risks and chemical background noise.
Modern analytical systems require laminar fluid profiles without turbulence or boundary-layer stagnation. Precision CNC-milled microchannels maintain edge radii under 10 µm and interior surface roughness Ra < 0.5 nm, preserving fluid integrity for single-cell sorting, cytometers, and high-resolution capillary electrophoresis.
