Brand: DAIHAN
Origin: HÀN QUỐC
Overview & Features
Quality Tier Positioning: Belongs to the Professional line, featuring exceptionally small geometric tolerances and a straightness that far surpasses the Economic line. This minimizes spin errors and sideband artifacts, ensuring high-resolution spectra on 400 MHz spectrometer systems.
Premium Non-Magnetic Glass: Fabricated from pure Borosilicate 3.3 glass (complying with Class I Type A standards). The material is completely free of magnetic impurities to prevent any distortion of the spectrometer's magnetic field.
100% Laser Inspection: Each individual tube undergoes a rigorous automated laser scanning measurement system at the factory to verify outer diameter, wall thickness, and geometric uniformity before being approved for release.
Traceability: Printed with a permanent Retrace Code on the body, enabling users to quickly look up and download the Certificate of Quality online.
Laboratory-Standard Packaging: The products are completely pre-cleaned prior to packaging and come supplied with flexible EVA plastic caps to securely and safely seal the samples.
