3 mm NMR Economy Sample Tube w/o Cap, 4" L, PK100, High-Throughput
Product No. Price Each Quantity Action
WG-3000-4 $127.55  

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-LabGlass 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.
