Wilmad-LabGlass Highthroughput NMR Tubes are manufactured from borosilicate glass that meets the ASTM Type 1 Class B standard and recognized as N51A. Due to its nature, this glass has much less thermal-shock resistance than Class A glass used for our Precision Tubes. It may contain Fe₂O₃ which is paramagnetic around 1200 ppm and has certain impact on shimming quality at high field over 600 MHz.

High Throughput NMR tubes have an averaged camber of 60 micron to gurantee the spectrum reolution for small melecules (MW<250) samples up to 600 MHz. Item is sold in plastic twist pack of 50 or paper pack of 100. Caps are not included and are purchased separately. The twist pack is made of polypropylene and resistant to common organic solvents. The packing materials are 100% recyclable.

Some of our competitors altered our MHz rating standard by advertising inferior tubes for higher magnetic field experiments. Please visit our NMR Economy Tube Cross Reference Guide to make a head-to-head comparison including pricing. The products listed on the same row will have the same performance at the same magnetic field IF the specifications of our competitors' product are guaranteed as advertised. From this guide we will prove our 60 year philosophy again as "committed to providing customers with cost-effective NMR consumables of the highest quality".

Note 1: Impact on shimming quality varies upon magnetic field strength. Economy tube is recommended for 1D low field experiments.

Note 2: Sample volume reproducibility refers to the maximum volume fluctuation when filling different NMR tubes to the same sample height. This number correlates to the reproducibility of time domain signal amplitude between different runs.
