With a 5 mm diameter and 7" length, these borosilicate glass tubes are manufactured in an ISO 9001:2008 certified facility, ensuring the highest quality standards. Each tube undergoes rigorous inspection to guarantee durability and compliance with ASTM E438 Type 1 Class B standards. This pack of 5 is perfect for any laboratory setting. ## Description Wilmad-LabGlass Economy 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 (1200 ppm) and has certain impact on shimming quality depending on the magnetic field strength. Economy tubes are recommended only for experiments with small organic molecule (Molecular Weight ~500) at ambient temperature only. The camber and concentricy listed in the product specification table is the upper limit value. Wilmad does not require a minimum purchase quanity. The unit price is one single tube. Each tube comes with a disposable cap.Cooling/heating of these tubes may lead to breakage. For NMR experiments that involve cooling, heating, biological sample, multi-dimension, multi-nuclei or DNP techniques; please refer to our Precision brand NMR Tubes. 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". ## Features - Best od tolerance in the industry and a 30 percent thicker wall than any competitors' product - Manufactured in an iso 9001:2008 usa facility - Camber and concentricity values listed are the total indicator reading (tir) - 100 percent visual and physical inspection ensures quality, including physical dimensions and surface defects - Made from borosilicate glass; meets astm E438 type 1 class b standard, recognized as n51a ## Images ![Wilmad WG-1242-7 Economy 5 mm NMR Sample Tube, 700 MHz, 7" L (Pack of 5) - Image 1](https://m.media-amazon.com/images/I/31Xp46MnvDL.jpg) ![Wilmad WG-1242-7 Economy 5 mm NMR Sample Tube, 700 MHz, 7" L (Pack of 5) - Image 2](https://m.media-amazon.com/images/I/61PP0CNOtpL.jpg) ![Wilmad WG-1242-7 Economy 5 mm NMR Sample Tube, 700 MHz, 7" L (Pack of 5) - Image 3](https://m.media-amazon.com/images/I/81N8tJdGHeL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Value NMR tubes *by R***R on Reviewed in the United States on November 29, 2020* Great NMR tubes at a great price.
