Description 3mm Economy NMR Tubes With the steady increase of SNR on modern NMR spectrometers, the trend of small volume testing fits in high-throughput NMR to save on solvent costs. Wilmad presents a 3mm OD Economy Sample Tube with the same outstanding quality and performance as our legendary 5mm line. The new 4″ version is designed for Bruker®’s SampleJet™ system and possesses a tighter tolerance for use with the SampleJet™ cap which is sold separately. All are shipped in our reusable polyethylene Twist-Pack which provides contamination-free, chemically resistant and mechanically robust protection. Details 50 tube pack now comes with caps.
