KONTES* NMR Tubes

Used extensively in high resolution NMR spectroscopy. Manufactured from ASTM Type 1 borosilicate glass. These precision tubes are used with 60 to 200 MHz NMR spectrometers. Their low tolerances held in wall variation chamber make them especially suitable for use in instruments at higher field strengths (200 - 500 MHz). Each tube is supplied with a cap and a sandblasted marking spot for sample identification. T.I.R. is the total indicator reagent in inches.
