Overview & Features
Top-Tier Quality Positioning: Part of the Scientific line, this product range meets the manufacturer's most stringent geometric tolerance standards. This design virtually eliminates spin errors, peak distortions, and sideband artifacts, ensuring complex molecular structures are resolved with absolute clarity and precision.
Ultra-Pure Borosilicate 3.3 Glass: The tubes are fabricated entirely from DURAN Borosilicate 3.3 thermal glass. The material is completely free of magnetic impurities to prevent any interference with the magnetic fields of high-intensity superconducting magnets.
Excellent Straightness and Uniformity: Camber is tightly controlled to an extreme limit. This ensures the tubes operate with maximum safety and smoothness on automated sample changers (Autosamplers) or during high-throughput screening procedures without risk of jamming or breakage.
Rigorous Quality Management: Each individual tube undergoes automated laser inspection scanning at the German factory. The tube body features an integrated Retrace Code, allowing users to download the Certificate of Quality for that specific production batch online.
Premium Standard Packaging: Comes supplied complete with specialized plastic caps to securely seal the samples and prevent the evaporation of expensive deuterated solvents.
